Keeping up with Cloud Native (Ep 17)

If you work in Kubernetes, cloud native, or any other fast-moving ecosystem, you might have found that keeping up to date with new developments can be incredibly challenging. We think this as well, and so we decided to make today’s episode a tribute to that challenge, as well as a space for sharing the best resources and practices we can think of to help manage it. Of course, there are audiences in this space who require information at various levels of depth, and fortunately the resources to suit each one exist. We get into the many different places we go in order to receive information at each part of the spectrum, such as SIG meetings on YouTube, our favorite Twitter authorities, the KubeWeekly blog, and the most helpful books out there. Another big talking point is the idea of habits or practices that can be helpful in consuming all this information, whether it be waiting for the release notes of a new version, tapping into different TLDR summaries of a topic, streaming videos, or actively writing posts as a way of clarifying and integrating newly learned concepts. In the end, there is no easy way, and passionate as you may be about staying in tune, burnout is a real possibility. So whether you’re just scratching the cloud native surface or up to your eyeballs in base code, join us for today’s conversation because you’re bound to find some use in the resources we share. Follow us: https://twitter.com/thepodlets Website: https://thepodlets.io Feeback: info@thepodlets.io https://github.com/vmware-tanzu/thepodlets/issues Hosts: Carlisia Campos Josh Rosso Duffie Cooley Olive Power Michael Gasch Key Points From This Episode: Audiences and different levels of depth that our guests/hosts follow Kubernetes at. What ‘keeping up’ means: merely following news, or actually grasping every new concept? The impossibility of truly keeping up with Kubernetes as it becomes ever more complex. Patterns used to keep up with new developments: the TWKD website, release notes, etc. Twitter’s helpful provision of information, from opinions to tech content, all in one place. How helpful Cindy Sridharan is on Twitter in her orientation toward distributed systems. The active side of keeping up such as writing posts and helping newcomers. More helpful Twitter accounts such as InfoSec. How books provide one source of deep information as opposed to the noise on Twitter. Books: Programming Kubernetes; Managing Kubernetes; Kubernetes Best Practices. Another great resource for seeing Kubernetes in action: the KubeWeeky blog. A call to watch the SIG playlists on the Kubernetes YouTube channel. Tooling: tab management and Michael’s self-built Twitter searcher. Live streaming and CTF live code demonstrations as another resource. How to keep a team updated using platforms like Slack and Zoom. The importance of organizing shared content on Slack. Challenges around not knowing the most important thing to focus on. Cognitive divergence and the temptation of escaping the isolation of coding by socializing. The idea that not seeing keeping up to date as being a personal sacrifice is dangerous. Using multiple different TLDR summaries to cement a concept in one’s brain. Incentives for users rather than developers of projects to share their experiences. The importance of showing appreciation for free resources in keeping motivation up. Quotes: “An audience I haven’t mentioned is the audience that basically just throws up their hands and walks away because there’s just too much to keep track of, right?” — @mauilion [0:05:15] “Maybe it’s because I’m lazy, I don’t know? But I wait until 1.17 drops, then I go to the release notes and really kind of ingest it because I’ve just struggled so much to kind of keep up with the day to day, ‘We merged this, we didn’t merge this,’ and so on.” — @joshrosso [0:10:18] “If you find value in being up to date with these things, just figure out – there are so many resources out there that address these different audiences and figure out what the right measure for you is. You don’t have to go deep on the code on everything.” — @mauilion [0:27:57] “Actually putting the right content in the right channel, at least from a higher level, helps me decide whether I want to like look at that channel today, and stuff that should be in the channel is not kind of in a conversation channel.” — @opowero [0:32:21] “When I see something that is going to give me the fundamentals, like I have other priorities now, I sort of always want to consume that to learn the fundamentals, because I think in the long term phase of, but then I neglect physically what I need to know to do in the moment.” — @carlisia [0:33:39] “Just do nothing, because our brain needs that. We need to not be listening, not be reading, just nothing. Just sit and look at the ceiling. Our brain needs that. Ideally, look at nature, like look outside, look at the air, go for a walk. We need that, because that recharges the brain.” — @carlisia [0:42:38] “Just consuming and keeping up, that doesn’t necessarily mean you don’t give back.” — @embano1 [0:49:32] Links Mentioned in Today’s Episode: Chris Short — https://chrisshort.net/ Last Week in Kubernetes Development — http://lwkd.info/ 1.17 Release Notes — https://kubernetes.io/docs/setup/release/notes/ Release Notes Filter Page — https://relnotes.k8s.io/ Cindy Sridharan on Twitter — https://twitter.com/copyconstruct InfoSec on Twitter — https://twitter.com/infosec?lang=en Programming Kubernetes on Amazon —https://www.amazon.com/Programming-Kubernetes-Developing-Cloud-Native-Applications/dp/1492047104 Managing Kubernetes on Amazon — https://www.amazon.com/Managing-Kubernetes-Operating-Clusters-World/dp/149203391X Brendan Burns on Twitter — https://twitter.com/brendandburns Kubernetes Best Practices on Amazon — https://www.amazon.com/Kubernetes-Best-Practices-Blueprints-Applications-ebook/dp/B081J62KLW/ KubeWeekly — https://kubeweekly.io/ Kubernetes SIG playlists on YouTube — https://www.youtube.com/channel/UCZ2bu0qutTOM0tHYa_jkIwg/playlists Twitch — https://www.twitch.tv/ Honeycomb — https://www.honeycomb.io/ KubeKon EU 2019 — https://events19.linuxfoundation.org/events/kubecon-cloudnativecon-europe-2019/ Aaron Crickenberger on LinkedIn — https://www.linkedin.com/in/spiffxp/ Stephen Augustus on LinkedIn — https://www.linkedin.com/in/stephenaugustus Office Hours — https://github.com/kubernetes/community/blob/master/events/office-hours.md Transcript: EPISODE 17[INTRODUCTION][0:00:08.7] ANNOUNCER: Welcome to The Podlets Podcast, a weekly show that explores Cloud Native one buzzword at a time. Each week, experts in the field will discuss and contrast distributed systems concepts, practices, tradeoffs and lessons learned to help you on your cloud native journey. This space moves fast and we shouldn’t reinvent the wheel. If you’re an engineer, operator or technically minded decision maker, this podcast is for you.[EPISODE][0:00:41.5] DC: Good afternoon everybody and welcome to The Podlets. In this episode, we’re going to talk about, you know, one of the more challenging things that we all have to do, just kind of keep up with cloud native and how we each approach that and what we do. Today, I have a number of cohosts with me, I have Olive Power.[0:00:56.6] OP: Hi.[0:00:57.4] DC: Carlisia Campos.[0:00:58.6] CC: Hi everybody.[0:00:59.9] DC: Josh Rosso.[0:01:01.3] JR: Hey all.[0:01:02.8] DC: And Michael.[0:01:01.1] MICHAEL: Hey, hello.[0:01:04.8] DC: This episode, we’re going to do something a little different than we normally do. In most of our episodes, we try to remain somewhat objective around the problem and the potential solutions for it, rather than prescribing a particular solution. In this episode, however, since we’re talking about how we keep up with all of the crazy things that happen in such a fast ecosystem, we’re going to probably provide quite a number of examples or resources that you yourself could use to drive and to try and keep up to date with what’s happening out there.Be sure to check out the notes after the episode is over at thepodlets.io and you will find a link to the episodes up at the top part, click down to this episode, and check out the notes. There will be tons of resources. Let’s get started.One of the things I think about that’s interesting about keeping up with something like, you know, a Kubernetes or a fast-moving project, regardless of what that project is, whether it’s Kubernetes or, you know, for a while, it was the Mesos that I was following or OpenStack or a number have been big infrastructure projects that have been very fast moving over time and I think what’s interesting is I find that there’s multiple audiences that we kind of address when we think about what it means to ‘keep up,’ right?Keeping up with something like a project is interesting because I feel like there’s an audience that it’s actually very interested in what’s happening with the design goals or the code base of the project, and there’s an audience that is very specific to wanting to understand at a high level – like, “Give me the State of the World report like every month or so just so I can understand generally what’s happening with the project, like is it thriving? Is it starting to kind of wane? Are there big projects that it’s taking on?”And then there’s like, then I feel like there’s an audience somewhere in the middle there where they really want to see people using the project and understand, and know how to learn from those people who are using it so that they can elevate their own use of that project. They’re not particularly interested in the codebase per se but they do want to understand, are they exploring this project at a depth that makes sense for themselves? What do you all think about that?[0:03:02.0] CC: I think one thing that I want to mention is that this episode, it’s not so much about on-boarding people onto Kubernetes and the Kubernetes ecosystem. We are going to have an episode soon to talk specifically about that. How you get going, like get started. I think Duffy mentioned this so we’re going to be talking about how we all keep up with things. Definitely, there are different audiences, even when we’re talking about keeping up.[0:03:32.6] JR: Yeah, I think what’s funny about your audience descriptions, Duffy, is I feel like I’ve actually slid between those audiences a bit, right? It’s funny, back in the day, Kubernetes like one-four, one-five days, I feel like I was much more like, “What’s going on in the code?” Like trying to keep track of like how things are progressing.Now my role is a lot more focused with working with customers and standing up cube and like making a production ready. I feel like I’m a lot more, kind of reactive and more interested to see like, what features have become stable and impact me, you know what I mean? I’m far less in the weeds than I used to be. It’s a super interesting thing.[0:04:08.3] OP: Yeah, I tend to – for my role, I tend to definitely fall into the number three first which is the kind of general keeping an eye on things. Like when you see like interesting articles pop up that maybe have been linked internally because somebody said, “Oh, check out this article. It’s really interesting.”Then you find that you kind of click through five or six articles similar but then you can kind of flip to that kind of like, “Oh, I’m kind of learning lots of good stuff generally about things that folks are doing.” To actually kind of having to figure out some particular solution for one of my customers and so having to go quite deep into that particular feature.You kind of go – I kind of found myself going right in and then back out, right in, going back out depending on kind of where I am on a particular day of the week. It’s kind of a bit tricky. My brain sometimes doesn’t kind of deal with that sort of deep concentration into one particular topic and then back out again. It’s not easy.I find it quite tough actually some of the time.[0:05:05.0] DC: Yeah, I think we can all agree on that. Keeping track of everything is – it’s why the episode, right? How do we even approach it? It seems – I feel like, an audience I haven’t mentioned is the audience that basically just throws up their hands and walks away because there’s just too much to keep track of, right? I feel like we are all that at some point, you know?I get that.[0:05:26.4] OP: That’s why we have Christmas holidays, right? To kind of refresh the brain.[0:05:31.4] CC: Yeah, I maybe purposefully or maybe not even – not trying to keep up because it is too much, it is a lot, and what I’m trying to do is, go deeper on the things that I already, like sort of know. And things that I am working with on a day to day basis. I only really need to know, I feel like, I really only need to know – because I’m not working directly with customers.My scope is very well defined and I feel that I really only need to know whenever there’s a new Kubernetes release. I need to know what the release is. We usually – every once in a while, we update our project to the – we bump up the Kubernetes release that we are working against and in general, yeah, it’s like if things come my way, if it’s interesting, I’ll take a look, but mostly, I feel like I work in a spiral.If I’m doing codes related to controllers and there’s a conference talk about controllers then okay, let me take a look at this to maybe learn how to design this thing better, implement in a better way if I know more about it. If I’m doing, looking at CRDs, same thing. I really like conference talks for education but that’s not so much keeping up with what’s new. Are we talking about educating ourselves with things that we don’t know about?Things that we don’t know about. Or are we talking about just news?[0:07:15.6] JR: I think it’s everything. That’s a great question. One of my other questions when we were starting to talk about this was like, what is keeping up even mean, right? I mean, does it mean, where do you find resources that are interesting that keep you interested in the project or are you looking for resources that just kind of keep you up to date with what’s changing? It’s a great question.[0:07:36.2] MICHAEL: Actually, there was some problem that I faced when I edit the links that I wanted to share in the show. I started writing the links and then I realized, “Well, most of the stuff is not keeping up with news, it’s actually understanding the technology,” because I cannot keep up.What does help me in understanding specific areas, when I need to dig into them and I think back five or four years into early days of Kubernetes, it was easy to catch up by the time because it was just about Kubernetes. Later right, it became this platform. We realized that it actually this platform thing. Then we extended Kubernetes and then we realized there are CICD-related stuff and operations and monitoring and so the whole ecosystem grew. The landscape grew so much that today, it’s impossible to keep up, right?I think I’m interested in all those patterns that you have developed over the years that help you to manage this, let’s say complexity or stream of information.[0:08:33.9] DC: Yeah, I agree. This year, I was thinking about putting up a talk with Chris Short, it was actually last year. That was about kind of on the same topic of keeping up with it. In that, I kind of did a little research into how that happens and I feel like some of the interesting stuff that came out of that was that there are certain patterns that a project might take on that make it easier or more approachable to, you know, stay in contact with what’s happening.If we take Kubernetes as an example, there are a number of websites I think that pretty much everybody here kind of follows to some degree, that helps, sort of, kind of, address those different audiences that we were talking about.One of the ones that I’ve actually been really impressed with is LWKD which stands for Last Week in Kubernetes Development, and as you can imagine, this is really kind of focused on, kind of – I wouldn’t say it’s like super deep on the development but it is watching for things that are changing, that are interesting to the people who are curating that particular blog post, right?They’ll have things in there like, you know, code freezes coming up on this date, IPV6, IPV4, duel stack is merging, they’ll have like some of the big mile markers that are happening in a particular release and where they are in time as it relates to that release. I think if that’s a great pattern and I think that – it’s a very narrow audience, right? It would really only be interesting to people who are interested in, or who are caught up in the code base, or just trying to understand like, maybe I want a preview of what the release notes might look like, so I might just like look for like a weekly kind of thing.[0:10:03.4] JR: Yeah, speaking of the release notes, right? It’s funny. I do get to look at Last Week in Kubernetes development every now and then. It’s an awesome resource but I’ve gotten to the point where the release notes are probably my most important thing for staying up to date.Maybe it’s because I’m lazy, I don’t know, but I wait till 1.17 drops, then I go to the release notes and really kind of ingest it because I’ve just struggled so much to kind of keep up with the day to day, “We merged this, we didn’t merge this,” and so on. That has been a huge help for me, you know, day to day, week to week, month to month.[0:10:37.0] MICHAEL: Well, what was also helpful just on the release notes that the new filter webpage that they put out in 1.15, starting 1.15. Have you all seen that?[0:10:44.4] JR: I’ve never heard of it.[0:10:45.4] DC: Rel dot, whatever it is. Rel dot –[0:10:47.7] MICHAEL: Yeah, if you can share it Duffy, that’s super useful. Especially like if you want to compare releases and features added and –[0:10:55.2] DC: I’ll have to dig it up as well. I don’t remember exactly what –[0:10:56.7] CC: I’m sorry, say? Which one is that again?[0:10:59.1] MICHAEL: The real notes. I’ll put it in the hackMD.[0:11:02.8] DC: Yeah relnotes.k8s.io which is an interesting one because it’s sort of like a comparison engine that allows you to kind of compare what it would have featured like how to feature relates to different versions of stuff.[0:11:14.4] CC: That’s great. I cannot encourage enough for the listeners to look at the show notes because we have a little document here that we – can I? The resources are amazing. There are so many things that I have never even heard about and sound great – is – I want to go to this whole entire list. Definitely check it out. We might not have time to mention every single thing. I don’t want people to miss on all the goodness that’s been put together.[0:11:48.7] DC: Agreed, and again, if you’re looking for those notes, you just go to the podlets.io. Click on ‘episodes’ at the right? And then look for this episode and you’ll find that it’s there.[0:11:58.0] CC: I can see that a lot of the content in those notes are like Twitter feeds. Speaking personally, I’m not sure I’m at the stage yet where I learn a lot about Twitter feeds in terms of technical content. Do you guys find that it’s more around people’s thoughts around certain things so thought-provoking things around Kubernetes and the ecosystem rather than actual technical content. I mean, that’s my experience so far.But looking at those Twitter feeds, maybe I guess I might need to follow some of those feeds. What do you all think?[0:12:30.0] MICHAEL: Do you mean the tweets are from those like learn [inaudible 0:12:32] or the person to be tweets?[0:12:35.3] OP: You’ve listed some of there, Michael, and some sort of.[0:12:37.6] MICHAEL: I just wanted to get some clarity. The reason I listed so many Twitter accounts there is because Twitter is my only kind of newsfeed if you will. I used Feedly and RSS and others before and emails and threads. But then I just got overwhelmed and I had this feeling of missing out on all of those times.That’s why I said, “Okay, let’s just use Twitter.” To your question, most of these accounts are people who have been in the Kubernetes space for very long, either running Kubernetes, developing on Kubernetes, having opinions about Kubernetes.Opinions in general on topics related to cloud native because we didn’t want to make the search just about Kubernetes. Most of these people, I really appreciate their thoughts and some of them also just a retweet things that they see which I missed somewhere else and not necessarily just opinions. I think It’s a good mix of these accounts, providing options, some guidance, and also just news that I miss out on because not being on the other channels.[0:13:35.6] OP: Yeah, I agree because sometimes you can kind of read – I tend to require a lot of sort of blog posts and sort of web posts which, you know, without realizing it can be kind of opinionated and then, you know, it’s nice to then see some Twitter feeds that kind of actually just kind of give like a couple of words, a kind of a different view which sometimes makes me think “Okay, I understand that topic from a certain article that I’ve read, it’s just really nice to hear a kind of a different take on it through Twitter.”[0:14:03.0] CC: I think some of the accounts, like fewer of the accounts – and there are a bunch of things that – there are listed accounts here that I didn’t know before so I’ll check them out. I think fewer of the accounts are providing technical content, for example, Cindy Sridharan, not pronouncing it correctly but Cindy is great, she puts out a lot of technical content and a lot of technical opinion and observations that is really good to consume. I wish I had time to just read her blog posts and Twitter alone.She’s very oriented towards distributed systems in general, so she’s not even specific just Kubernetes. Most of the accounts are very opinionated and the benefit for me is that sometimes I catch people talking about something that I didn’t even know was a thing. It’s like, “Oh, this is a thing I should know about for the work that I do,” and like Michael was saying, you know, sometimes I catch retweets that I didn’t catch before and I just – I’m not checking out places, I’m not checking – hash tagging Reddit.I rely on Twitter and the people who I follow to – if there is a blog post that sounds important, I just trust that somebody would, that I’m going to see it multiple times until like, “Okay, this is content that is related to something and I’m working on, that I want to get better at.” Then I’ll go and look at it. My sources are mainly Twitter and YouTube and it’s funny because I love blog posts but it’s like I haven’t been reading them because it takes a long time to read a blogpost.I give preference to video because I can just listen while I’m doing stuff. I sort of stopped reading blog post which is sad. I also want to start writing posts because it’s so helpful for me to engrain the things that I’m learning and hopefully it will be helpful to other people too. But in any case, go Duffy.[0:16:02.8] DC: A number of people that I follow – I have been cultivating my feed pretty carefully, trying to get a broad perspective of technical stuff that’s happening. But also I’ve been trying to develop my persona on Twitter a bit more, right? I’m actually trying to build my audience there. What’s interesting there is I’ve been trying to – to that end, what I’ve been doing is like trying to amplify voices that I think aren’t heard enough out there, right?If I see an article by somebody who is just coming into Kubernetes. or just coming into distributed systems and they’ve taken an effort to really lay out something that they found really interesting about pretty much anything, right? I’m like, “Okay, that’s pretty awesome,” and I’ll try to amplify that, right? Sometimes I even get involved or I’ll, not directly in public on Twitter but I’ll offer to help edit or help provide whatever our guidance I can provide around that sort of stuff.If I see people like having a difficult time with a particular project or something like that, I’ll reach out privately and say, “Hey, can I help you with it so you can go out there and do a great job,” you know? That is something I love to do. I think your point about like not necessarily going at Twitter for the deep knowledge stuff but more just like making sure that you have a broad enough awareness of what’s happening in different ecosystems that you’re not surprised by the things when the things change, right?A couple of other people that I follow are Akira Asuta, I can’t say enough about that person. They are amazing, they have been doing like, incredibly deep security stuff as it relates to containerization and stuff like that for quite a while. I’m always like, learning brand new things to me when following folks like that. I’ve been kind of getting more interested in InfoSec Twitter lately, learning how people kind of approach that problem.Also some of the bias arounds that which has been pretty interesting. Both the bias against people who are in InfoSec which seems weird to me. Also, how InfoSec approaches a problem, like do they put it like a learning experience or they approach it like an attack experience.It’s been kind of fascinating to get in there.[0:18:08.1] OP: You know, I kind of use Twitter as well for some of this stuff but you know, books are kind of a resource as well but in my head, kind of like at the opposite scale. You know, I obviously don’t read as many books as I read twitter feeds, right? It’s just kind of like, with Twitter, you can kind of digest the whole of the stuff and with books, it’s kind of like – I tend to be trying – because I know, I’m only going to read – like I’m only going to read maybe one/two books a year.I’ve kind of like – as I said before, blog posts seem to take up my reading time and books kind of tend to be for like on airplanes and stuff. So if – they’re just kind of two opposite resources for me but I find actually, the content of books are probably stuff that I digest a bit more because you know, it’s kind of like, I don’t know, back to the old days. It’s kind of a physical thing on hand and I can kind of read it and digest it a bit more than the kind of throwaway stuff that kind of keeps on Twitter.Because to be honest, I don’t know what’s on Twitter. Who is kind of a person to listen to or who is not or who is – I just try and form my own opinions and then, again, it kind of gets a bit overwhelming, because it’s a lot of content just streaming through continuously, whereas a book, it’s kind of like just one source of information that is kind of like a bit more personal that I can digest a bit more.[0:19:18.1] JR: Any particular book recommendation in 2019, Olive, that you found particularly interesting?[0:19:23.5] OP: I’m still reading, and it’s on the list for the episode notes actually, Programming Kubernetes. I just want to kind of get into that sort of CRD sort of mindset a bit. I think that’s kind of an area that’s interesting and an area that a lot of people will want to use in their organizations, right, because it’s going to do some of the extensibility to Kubernetes that’s just not there out of the box and everybody wants something that’s not out of the box or always in my experience.[0:19:47.4] MICHAEL: I found the Managing Kubernetes, I think was it, by – from Brendan Burns and some other folks which was just released I think in the end of last year. Super deep and that is kind of the opposite to the Programming Kubernetes, because I like that as well. That is more geared towards understanding architecture and operations.Operational concepts –[0:20:05.0] OP: They’re probably the two books I’ve read.[0:20:08.4] MICHAEL: Okay.[0:20:08.9] OP: One a year, remember?[0:20:11.4] MICHAEL: Yeah.[0:20:14.6] OP: Prolific reading.[0:20:19.6] CC: I think if you know what you need to learn about cloud native or Kubernetes, there’s amazing books out there, and if you are still exploring Kubernetes and trying to learn, I cannot recommend this book enough. If you are watching this on YouTube, you’ll see the cover. It’s called Kubernetes Best Practices because it’s about Kubernetes best practices but what they did simultaneously and maybe they didn’t even realize is just they gave a map for the entire thing.You go, “Oh, these are all the elements in Kubernetes.” Of course, it’s saying, “Okay, this is the best way to go about setting the stuff up,” and this is relatively thin but I just think that going through this book, you get really fast overview of the elements in Kubernetes. Then you can go to other books like Managing Kubernetes to go deep and understand all of the knobs and switches.[0:21:24.6] DC: I want to bring it back to the patterns that we see successful projects. Projects that you think are approachable but, you know, projects that are out there that make it easy for you to kind of stay – or easier at least to stay up to date with them, what some of those patterns are that you think are useful for projects.We’re talking about like having a couple of different entry points from kind of a weekly report mechanism, we’ve talked about the one that LWKD is, I don’t think we got to talk about KubeWeekly which is actually a weekly blog that is actually curated by a lot of the CNCF ambassadors. KubeWeekly is also broken up in different sections, so like sometimes they’ll just talk about – but they’re actually going out actively and trying to find articles of people using Kubernetes and then trying to post those.If you’re interested in understanding how people are actually out there using it, then that’s a great place to go find articles that are kind of related to that. What are some other patterns that we see that are out there that are useful for books?[0:22:27.6] DC: One that I really like. Kubernetes, for everyone listening has this notion of special interest groups, SIGs oftentimes. They’re focused on certain areas of the project. There’s some for networking and storage and life cycles of clusters and what’s amazing, I try to watch them somewhat weekly, I don’t always succeed.They’re all on YouTube and if you go to the Kubernetes project YouTube, there’s playlists for every SIG. A lot of times I’m doing work relating to life cycles of clusters. I’ll open up the cluster life cycle playlist and I’ll just watch the weekly meetings. While it doesn’t always pertain to completely to me, it lets me understand kind of where the developers and contributor’s heads are at and where they’re kind of headed with a lot of different things.There’s a link to that as well if anyone wants to check it out.[0:23:15.9] MICHAEL: Exactly, to add to that. If you don’t have the time to watch the videos, the meeting notes that these gentlemen and women put together are amazing. Usually, I just scroll through and if it’s something to triggers, I go into the episode and watch it.[0:23:28.7] OP: I almost feel like we should talk about tooling to handle all of this stuff, for example, right now, I think I have 200 tabs opened. I just started learning about some chrome extensions to manage tabs. I haven’t started really using them but I need. I don’t have a good system. My system is open a video that I’m pretty sure I want to watch and just get to that tab eventually until something happens in my chrome goes bust and I lose everything.I wanted to mention that when we say watch YouTube, some things you don’t need to sit there and actually watch, you can just listen to it and if you pay for the five bucks for YouTube premium – I don’t get a commission you people, but I’m just saying, for me, it’s so helpful. I can just turn off you know, put my phone on my pocket and keep listening to it without having to have the phone open and on the whole time. It’s very handy.It’s just like listening to a podcast. I also listen to podcasts lots of days.[0:24:35.1] MICHAEL: For tooling, since I’m just mostly on Twitter and by the time I was using or starting to use Twitter, they didn’t have this bookmark function, so I was basically abusing likes or favorites at the time, I think, to bookmark. What I realized later, my bookmarks grew, well, my likes grew.I wanted to go back and find something but that through the Twitter search was just impossible. I blew the tiny little go tool, kind of my first exercise there to just parse my likes and then use JQ because it’s all JSON to query and manipulate the stuff. I almost use it every day because I was like, that was a talk or blog post about scheduling and just correct for scheduling and the likes.I’m sure there’s a better tool or way of doing that but for me, that’s mine too. Because that’s my workflow.[0:25:27.6] DC: Both of the two blogs that you mentioned both KubeWeekly and LWKD, they both have the ability to take – you can submit stories to them. If you come across things that are interesting and you’d like to put that up on an aggregator somewhere, this is one of the ways to kind of solve that problem because at least if it gets cleared up on an aggregator, you know that you go back to the aggregator to see it, so that helps.Some other ones I’ve seen out there, I’ve seen people, I’ve seen a number of interesting startups now, starting to kind of like put out a podcast or – and I have started to see a number of people like you know, engaging with Twitch and also doing things like what we do with TJK.io which is like have sort of some kind of a weekly thing where you are just hacking on stuff live and just exploring it whether that is related to – if you think of about TJK is we’re going to do without being related necessarily to anything that we are doing at VMware just anything to do with the community but obviously if you are working for one of the small companies like Honeycomb or some other company.A smaller kind of startup, you can really just get people more aware of that because for some reason people love to watch others code. They love to understand how people go through that, what are their thought process is and I find it awesome as well. I think it is amazing to me how big a draw that is, you know?[0:26:41.1] OP: And is there lots of them out there Duffy? Is that kind of an easy searchable thing or is it like how do you know those things are going on?[0:26:48.4] DC: Oddly enough Twitter, most of the time, yeah. I mean, most of the time I see that kind of stuff happening on Twitter, like somebody will like – I will scope with this or a number of other people will say, “Hey, I am going to do a live stream during this period of time on this,” and I have actually seen a number of people doing live streams on CTFs, which are capture the flags. That one’s really been fascinating to me because it has been how do people think about approaching the security of an application.Like where do they look for weak spots and how do you determine, how do you approach that kind of a problem, which is fascinating. So yeah, I think it is important to remember that like you know, you are not the only one trying to keep up to date with all of this stuff, right? The one thing we all have said pretty consistently here is that it is a lot, and it is not just Kubernetes, right? Like any fast moving project. It could be your favorite Ruby module that has 200 contributors, right?It doesn’t matter what it is, it is a lot to keep a track of, and it represents some of that cognitive overheads that you have to think about. That is a lot to take on. Even if it is overwhelming, if you find value in being up to date with these things, just figure out – there are so many resources out there that address these different audiences and figure out what the right measure for you is. You don’t have to go deep on the code on everything.Sometimes it might be better to just try and find a source of information that gives you a high enough of a view. Maybe you are looking at the blog posts that come out on Kubernetes.io every release and you are just looking at the release notes and if you just read the release notes every release, that is already miles ahead of what I have seen a lot of folks out there when they are starting to ask me questions about how do you keep up to date.[0:28:35.9] JR: I’m curious, we have been talking a lot about keeping up as an individual. Do you all have strategies for how you help, let’s say your overall team, keep up with all the things that are going on? To give an example, Duffy, Olive and myself, at least at one point, were on the same team and we’d go out to disparate customers and see all of these different new things that they are trying to do or new projects that they are using.So we’d have to think about how do we get together and share that internally to make sure we are bringing the whole team along with what is going on in the ecosystem especially from a customer perspective. I know one of the ways that we do that is having demos and things of that nature that we share weekly. Are there other strategies that you all use with your teams to kind of share interesting information and news?[0:29:25.5] M: So what we do is mostly the way we share in our team, and we are a small team. We use Slack. We pre-filter in terms of like if there is stuff that I think is valuable for me and probably not for the whole team – obviously we are not going to share, but I think if it is related to something that the team has or to come grant and then I will share on Slack but we don’t have any formal way. I know people use some reports, weekly reports, or other platforms to distribute but we just use Slack.[0:29:53.0] DC: I think one of the things – one of the patters that we had at [inaudible 0:29:54] that I thought was actually super helpful was that we would engage a conversation. “I learned a cool new thing about whatever today,” and so we would say, “I am going to – ” and then we would start a Zoom call around that and then people could join if they wanted to, to be a part of the live discussion or not, and if they didn’t, they would still be able to see a recorded Zoom pop up in the channel later on.So even if your time zones don’t line up, like I know it is 2 AM or 3 AM or something like that for Olive right now, you can still go back to those recorded sessions and you’ll just see it on your daily Slack stuff. You would be able to see, “Oh there was a conversation about whether you should deploy Kubernetes crossed availibility zones or not. I would like to go see that,” and see what the inputs were, and so that can be helpful.[0:30:42.5] JR: Yeah, that is a super interesting observation. It is almost like remote-first teams that are used to these processes of recording everything and putting it in a Google doc. They are more equipped for that information sharing perhaps than like the water cooler conversations you’d have in the office.[0:30:58.5] OP: And on the Slack or any of the communication tool, we have different channels because we are all in lots of channels and to have channels dedicated to a particular subject is absolutely the way to go because otherwise in my previous company that seem to be kind of one main channel that all the architect used to discussed everything on and you know sometimes you join and you’re like, “What is everybody talking about?”There would be literally about a hundred messages on some sort of theme that I have never heard of. So you come away from that thinking that, “That is the main channel. Where is the bit – is there messages in the middle that I missed that were just normal discussions as opposed to in around the technical stuff,” and so it made me a bit sad, right? I would be like, “I haven’t understood something and there is a whole load of stuff on this channel that I don’t understand.”But it is the kind of central channel for everyone. So I think you end up then start looking up things that they are discussing and then realizing actually that is not really anything related to what I need to know about today or next week. It might be something for the future but I’ve got other stuff to focus on. So my point is that those communication channels for me sometimes can make me feel a little bit behind the curve or very much sort of reactive in trying to jump on things that are actually not really anything to do with me for me now and wasting my time slightly and kind of messing with my head a little bit in that like, “I really need to try and focus out stuff,” and actually putting the right content in the right channel, at least from a higher level, helps me decide whether I want to like look at that channel today, and stuff that should be in the channel is not kind of in a conversation channel. So organization of where that content is, is important to me.[0:32:37.6] CC: I am so in the same page with you Olive. That is the way my brain works as well. I want to have multiple channels, like if we are talking about Slack or any chat tool, but some people have such aversion to multiple channels. They really have a hard time dealing with too many – like testing their threshold of what they think is too many channels. So I am always mindful too, like it has to work for everybody but if it was up to me, there will be one channel per topic. So I know where to focus on.But you said something that is so interesting. How do we even just – like you were saying in the context of channel, multiple channels, and I go, if I need to pay attention to this this week as oppose to like, I don’t need to look at this until some time in the future. How do we even decide what we focus on that is useful for us in the moment versus it would be good for me to know but I don’t need to know right now.I am super bad at this. When I see something that is going to give me the fundamentals, like I have other priorities now, I sort of always want to consume that to learn the fundamentals because I think in the long term phase of, but then I neglect physically what I need to know to do in the moment and I am trying to sort of fish there and get focused on in the moment things. Anybody else have a hard time?[0:34:04.5] DC: You are not alone on that, yeah.[0:34:06.7] CC: It is terrible.[0:34:08.3] MICHAEL: Something that I wish I would do more often as like being a good citizen is like when you read a lot, probably 90% of my time is not writing but reading, maybe even more and then I share and then on Twitter, the tweet for them the most successful ones in terms of retweets or likes are the ones where I do like TLDR’s or some screen captures like too long to read. Where people don’t have the time, they might want to read the article but they don’t have the time.But if you put in like a TLDR like either a tweet or a thread on it, a lot of people would jump onto it because they can just easily capture it and they can still read the full article if they want but that is something that I learned and it is pretty – what is the right word? Helpful to my followers and the community but I just don’t do it that often unfortunately. If I am writing, summarizing, writing, I kind of remember. That is how the brain works. It is a nice side effect.[0:35:04.9] DC: I was saying, this is definitely one of those things where you can be the change you want to see if you, you know?[0:35:08.6] M: Yeah, I know.[0:35:10.0] DC: This is awesome. I would also say that what you just raised Carlisia is like a super valid point. I mean like not everybody’s brain works the same way, right? There are people who are neuro-divergent. There are people who think very linearly and they are very comfortable with that and there are people who don’t. So it is a struggle I think regardless of how your brain is wired to understand to how to prioritize the attention you will give any given subject.In some cases, your brain is not wired – your brain is almost wired against that whole idea, like you are just not set up for success when it comes to figuring out how to prioritize your attention.[0:35:49.0] CC: You hit the nail on the head. We are so set up for failure in that department because there are so many interesting conversations and you want to hop in and you want to be a part of the conversation and part of the group and socialize. Our work is so isolating to really put our heads down and just work, it can be so isolating. So it is great to participate in conversations out there even if it is for only via Twitter. I mean, obviously we are very biased towards Twitter here in this group.But I am not even this on Twitter so just keep that in mind that we are cognizant of that but in any case, I don’t know what the answer is but what I am trying always to cut down on that, those social activities that seem so appealing. I don’t know how to do that from working out.[0:36:43.9] JR: I am in the same boat. 2020, I am hoping to let more of that go and to your point, it is not that there is no value in it. It is just, I don’t know, I am not deriving the same amount of quality out of it because I am so just multiplexed all over the place, right? So we’ll see how it goes.[0:36:59.9] CC: Oh if any listener has opinions and obviously it seems that all of us are helpless in that department. Share with us, please.[0:37:12.5] DC: It is a tricky one. I think it is also interesting because I find that when we talk about things like work-life balance, we think of the idea of maybe work-life balance is that when you come at the end of the day and you go home and you don’t think about work, right? Sometimes we think that work-life balance means that you have a certain amount of time off that you can actually spend with your family and your friends or your community, what have you, and not be engaging on multiple fronts.Just be that – have that be your focus, but when it comes to things like keeping up, when it comes to things like learning or elevating your education and stuff, it seems like, for the most part, and this is just my own assumption, I am curious how you all feel about this, that we don’t – that that doesn’t enter into it, right? Your personal time is totally on the table when it comes to how do you keep up with these things. We don’t even think about it that way, right?I know I personally don’t. I definitely have to do more and cut back on the amount of time that I spend reading. I am right there with Michael on 90% of my time when my eyes are open, they are either reading or staring up on the sky while I try to think about what I am going to write next. You know one way or the other it is like that is what I am doing.[0:38:24.0] CC: Yeah.[0:38:25.1] MICHAEL: I noticed last year on my Twitter feed, more people than the years before will complain about like personal burn out. I saw a pattern, like reading those people’s tweets, I saw a pattern there. It wasn’t really like a spiral and then they realized and they shot down like deleted Twitter from their phones or any messaging and other stuff, and I think I am at the point where I also need to do that when it comes to vacation PDO, or whatever.Because I am just like, as you said Duffy, my free time is on the table when it comes to Twitter and catching up and keeping up because work-life balance in my mind is not work but what is not work for like – Kubernetes is exciting, adding in all the space, like what is not work there? I need to really get better at that because I think I might end in the same spiral of just soaking in more until I just –[0:39:17.7] CC: Yeah and like Josh said, it is not that there isn’t a value. Obviously we derive a huge value, that is why we’re on it, but you have to weigh things and what are your goals and is that the best way to your goals from where you are right now, and maybe you know, Twitter you use for a while, ramp up your knowledge, ramp up the connections because it is great for making connections, and then you step back and focus on something else, then to go on a cycle.This is how I am thinking now. It is just like what Olive was saying, you know, books are great, blog posts are great, and I absolutely agree with that. It is just that I don’t have even the time and when I have the time, I would be reading code and I would be reading things all day long, it is just really tiring for me at the end of the day to sit down and read more. I want to invest in learning how to speed read to solve that problem because I read a lot of books and blog posts. So something on my list.[0:40:22.8] DC: One of the biggest tips on speed reading I ever learned is that frequently when you read you think of saying the word and if you can get out of that habit, if you get out of the habit of saying the word even with your mouth or you just get out of that habit that will already increase the quickness of what you read.[0:40:39.5] CC: That is so interesting.[0:40:41.4] DC: Yeah, that is a trippy one.[0:40:43.1] CC: Because I think being bilingual, I totally like – that really helps me understand things, by saying the words.[0:40:52.9] DC: I think the point that we are all working around here is, there is a great panel that came out at KubeCon EU in 2019 was put on by Aaron Crickenberger, Esther McNaMara, Steven Augustus, these folks are all very high output people. I mean, they do a lot of stuff especially with regard to community and so they put on a panel that was talking about burn out and self-care and I think that it is definitely worth checking that one out.And actually also thinking about what keeping up means to you and making sure that you are measuring that against your ability to sustain, is incredibly important, right? I feel like keeping up is one of those subjects where we end up – it is almost insidious in its way to – it is a thing that we can just do all the time. We can just spend all of our time, any free moment that you have, you are sitting on the bus, you are trying to keep up with things.And because that happens so much, I feel like that is sort of one of the ways that we can feel burnt out as you are seeing today. We can feel like we did a lot of things but there was no real result to it and keep in mind that that’s part of it, right? Like when you are thinking about how we are keeping up with it, make sure that the value to your time is still something that you have some cognizance about, that you have some thought about, like is it worth it to me to just spend this six hours reading everything, right?Or would it be better for me to spend some amount of time just not reading, you know? Like doing something else, you know? Like bake a cake for crying out loud, you know?[0:42:29.5] CC: Something that a lot of times we don’t allow ourselves to do and I decided to speak for everybody I am sorry, I just do nothing, because our brain needs that. We need to not be listening, not be reading, just nothing. Just sit and look at the ceiling, our brain needs that. Ideally, look at nature, like look outside, look at the air, go for a walk. We need that, because that recharges the brain. Anyway, one thing also that I want to bring up, maybe we can mention real quick because we are coming up at the top of the hour.How do people, projects, how do we really help the users of those projects to be up to date with what they are doing?[0:43:18.4] DC: Well yeah I mean this is the different patterns that we are talking about. So I think the blog posts help. I like the idea of having blogs that are targeted towards different audiences. I like the idea of having an aggregate here for putting up a big project. I mean obviously Kubernetes is such a huge ecosystem that if you have things like KubeWeekly and I know that there are actually quite a number of things out there that try and do this.But if we can kind of agree on one like KubeWeekly I think is a pretty good one because it is actually run by the CNCF. So it kind of falls within that sort of governance as a model but having an aggregator where you can actually produce content or curate content as it relates to your project that’s helpful, and then office-hours I think is also helpful to Josh’s point. I mean office-hours and SIG hours are very similar things. I mean like office-hours there like how to developers think about what’s happening with the space.This is an opportunity for you as an end user to show up and ask questions, those sorts of patterns I think all are incredibly helpful as a project to figure out there to those things.[0:44:17.8] OP: Yeah, I know summary articles or the sort of TLDRs that Michael mentioned earlier, I think I need more of those things in my life because I do a lot of reading, because I think my brain is a bit weird in that I need to read something about five or six different times from five or six different articles for it to sort of frame in my head.So what I am trying to – like for 2020, I have almost tried to do this, is like if I think somebody knows all about this and it would save me reading those five, six, seven articles and if that person has the time, I try and sort of reach out to them and say, “Listen, have you got 20 minutes or so to explain this topic to me? Can I ask you questions about it?” It just saves me, saves my eyes reading the screen, and it just saves me time. I just need a TLDR summary of a project or a feature or something just so I can know what it is all about in my head and talk fairly sort of confidently about it.If I need to get in front and down under the weeds then there is more reading to kind of do for me maybe the coding on the technical side, but sometimes I can’t figure out what this feature sort of means and what is its use case in the real world and I have to read through lots of articles and sometimes kind of vendor specific ones and they’ve got a different slant than maybe an independent one and trying to marry those bits up my head is a bit hard for me and there is sort of wealth of information.So if you are interested in a topic and there is hundreds of articles and you start reading four or five and they are all slightly different, eventually you figure out that – you are confident and I understand what that product is about but it has taken a long time to get there and it is taken a lot of reading time. So TLDRs is like really work and I think as Josh mentioned before, we have this thing internally where we do bench demos.And that is like a TLDR and a show and tell really quickly, like, “This is what this does and this is why we need to know about it and this is why our customers needs to know about it, the end,” you know? And that’s really, really useful because that just saves a whole bunch of people a whole bunch of time figuring out A, whether they need to know about it and B, actually now understanding that product or feature at the end of the five, 10 minutes which is what they typically are. So they are very useful short snippets of information. Maybe we are back to Twitter.[0:46:37.8] JR: Similar to the idea of giving a demo Olive, you made me think of something and that is that I think one of the ways that I keep up with the space is actually through writing along with reading and I think the notion of like – and this admittedly takes up time and the whole quality of life conversation comes in but using writing to help develop your thoughts and kind of aggregate all of these crazy inputs and try to be somewhat concise, which I know I struggle with, around something I’ve learned.It’s helped me a ton and then that asset kind of becomes reusable to share with other people the thing that you wrote. So for people listening to this I guess maybe a call to action for 2020 if that is your style as well, consider starting to write yourself and becoming a resource, right? Because even if you are new to this space, you’d be amazed at just how writing from your perspective can help other people.[0:47:26.3] DC: I think another one that I actually have been impressed with lately is that a number of consumer companies like people out there like Lyft and companies like that have actually started to surface engineering blogs around how they are using technology and how they are using technology to solve things, which I think, as a service provider, as somebody who is involved in the community of Kubernetes, I find those to be incredibly valuable because I get to actually see how those things are doing.I mean at the same time, I see things like – we talked about KubeCon, which is a convention that they have every year. Obviously the project is large enough to support it but there is actually an incentive if you are a consumer of that project to go and talk about how you are using it, right? It is incentivized in that it is more likely your talk will be accepted if you are a consumer of the product than somebody building it, right? We hear from people building it all the time.I love that idea of incentivizing people who are using this thing get out there and talk about it or share their ideas about it or how they are using it, what problems did it solve for them. That is critical I think.[0:48:31.0] CC: Can I also make a suggestion – is to not so much following on the thread that we are talking about just now but kind of on the general thread of this episode. If you have resources that you do use to keep up with things, stop this recording right now and go and give them a like, give them a follow, give them a thumbs up, show somehow appreciation because what Duffy said just now, he was saying, “Oh it is so helpful when I read a blog post.”But people who are writing, they want to know that. So give them some indication, it counts a lot. It takes a lot of effort to sit down and write something or produce a podcast and if you take any, derive any benefit from it, show appreciation. It motivates people to keep doing it.[0:49:26.4] DC: Yeah, agreed.[0:49:27.9] M: I think that is a great bind maybe to close off this episode because it reiterates that just consuming and keeping up that doesn’t necessarily mean you don’t give back, right? So this is a way of giving back, which is really important to keep that flow and creativeness.[0:49:41.8] CC: I go through a lot of YouTube videos and sometimes I just play one after the other but sometimes, you know, I have been making a point of going back and liking it. Liking the ones that I like – obviously I don’t like everything. I mean things that I don’t like I don’t listen in but you know what I mean? It takes no effort but just so people know, “OK, you did a good job here.” By the way, go to iTunes and rate us. So we will know that you liked it and it will help people find our show, our podcast, and if you are watching us on YouTube, give us a like.[0:50:16.1] DC: All right, well unless anybody has any final thoughts, that is what we wanted to cover this session. So thank you all very, very much and I look forward to seeing you next week.[0:50:25.3] M: Bye-bye.[0:50:26.3] CC: Thank you so much.[0:50:27.4] OP: Bye.[0:50:28.1] JR: Bye.[END OF EPISODE][0:50:28.7] ANNOUNCER: Thank you for listening to The Podlets Cloud Native Podcast.

The Past, Present and Future of Kubernetes with Craig McLuckie (Ep 13)

Play Episode Listen Later Jan 20, 2020 46:56

Today on The Podlets Podcast, we are joined by VMware's Vice President of Research and Development, Craig McLuckie! Craig is also a founder of Heptio, who were acquired by VMware and during his time at Google he was part of bringing Kubernetes into being. Craig has loads of expertise and shareable experience in the cloud native space and we have a fascinating chat with him, asking about his work, Heptio and of course, Kubernetes! Craig shares some insider perspective on the space, the rise of Kubernetes and how the increase in Kubernetes' popularity can be managed. We talk a lot about who can use Kubernetes and the prerequisites for implementation; Craig insists it is not a one-size-fits-all scenario. We also get into the lack of significantly qualified minds and how this is impacting competition in the hiring pool. Craig comments on taking part in the open source community and the buy-in that is required to meaningfully contribute as well as sharing his thoughts on the need to ship new products and services regularly. We finish off the episode with some of Craig's perspectives on the future of Kubernetes, dangers it poses to code if neglected and the next phase of its lifespan.

Each week, experts in the field will discuss and contrast distributed systems concepts, practices, tradeoffs and lessons learned to help you on your cloud native journey. This space moves fast and we shouldn’t reinvent the wheel. If you’re an engineer, operator or technically-minded decision maker, this podcast is for you. [INTERVIEW] [00:00:41] CC: Hi, everybody. Welcome back to The Podlets podcast, and today we have a special guest, Craig McLuckie. Craig, I have the hardest time pronouncing your last name. You will correct me, but let me just quickly say, well, I’m Carlisia Campos and today we also have Duffy Colley and Josh Rosso on the show. Say that three times fast, Craig McLuckie. Please help us say your last name and give us a brief introduction. You are super well-known in the Kubernetes community and inside VMware, but I’m sure there are not enough people that should know about you that didn’t know about you. [00:01:20] CM: All right. I’ll do a very quick intro. Hi, I’m Craig McLuckie. I’m a Vice President of Research and Development here at VMware. Prior of VMware, I spent a fair amount of time at Google where my friend Joe and I were responsible for building and shipping Google Compute Engine, which was an interesting exercise in bringing traditional enterprise virtualized workloads into the very sophisticated Google data center. We then went ahead and as our next project with Brendan Burns, started Kubernetes, and that obviously worked out okay, and I was also responsible for the ideation and formation of the Cloud Native Computing Foundation. I then wanted to work with Joe again. So we started Heptio, a little startup in the Kubernetes ecosystem. Almost precisely a year ago, we were acquired by VMware. So I’m now part of the VMware company and I’m working on our broader strategy around cloud native apps under the brand [inaudible 00:02:10]. [00:02:11] CC: Let me start off with a question. I think it is going to be my go-to first question for every guest that we have in the show. Some people are really well-versed in the cloud native technologies and Kubernetes and some people are completely not. Some people are asking really good questions out there, and I try to too as I’m one of those people who are still learning. So my question for you is what do you think people are asking that they are not asking the right frame, that you wish they would be asking that question in a different way. [00:02:45] CM: It’s a very interesting question. I don’t think there’s any bad questions in the world, but one question I encountered a fair bit is, “Hey, I’ve heard about this Kubernetes thing and I want one.” I’m not sure it’s actually the right question, right? Kubernetes is a powerful technology. I definitely think we’re in this sort of peak hype phase of the project. There are a set of opportunities that Kubernetes really brings a much more robust ability to manage, it abstracts a way infrastructure — there are some very powerful things. But to be able to be really successful with Kubernetes project, there’re a number of additional ingredients that really need to be thought through. The questions that ought to be asked are, "I understand the utility of Kubernetes and I believe that it would bring value to my organization, but do I have the skills and capabilities necessary to stand up and run a successful Kubernetes program?" That’s something to really think about. It’s not just about the nature of the technology, but it really brings in a lot of new concepts that challenge organizations. If we think about applications that exist in Kubernetes, there’s challenges with observability. When you think the mechanics of delivering into a containerized sort of environment, there are a lot of dos and don’ts that make a ton of sense there. A lot of organizations I’ve worked with are excited about the technology, but they don’t necessarily have the depth of understanding of where it's best used and then how to operate it. The second addendum to that is, “Okay, I’m able to deploy Kubernetes, but what happens the next day? What happens if I need to update it? When I need to maintain it? What happens when I discover that I need not one Kubernetes cluster or even 10 Kubernetes clusters, but a hundred or a thousand or 10,000.” Which is what we are starting to see out there in the industry. “Have I taken the right first step on that journey to set me up for success in the long-term?” I do think there’s just a tremendous amount of opportunity and excitement around the technology, but also think it’s something that organizations really need to look at as not just about deploying a platform technology, but introducing the necessary skills that are necessary to operate and maintain it and the supporting technologies that are necessary to get the workloads on to it in a sustainable way. [00:04:42] JR: You’ve raised a number of assumptions around how people think about it I think, which are interesting. Even just starting with the idea of the packaging problem that represents containerization is a reasonable start. So infrequently, do we describe like the context of the problems that — all of the problems that Kubernetes solve that frequently I think people just get way ahead of themselves. It’s a pretty good description. [00:05:04] DC: So maybe in a similar vein, Craig, we had mentioned all the pieces that go into running Kubernetes successfully. You have to bolt some things on maybe for security or do some things to ensure observability as adequate, and it seems like the ecosystem has taken notice of all those needs and has built a million projects and products around that space. I’m curious of your thoughts on that because it’s like in one way it’s great because it shows it’s really healthy and thriving. In another way, it causes a lot of fragmentation and confusion for people who are thinking whether they can or cannot run Ku, because there are so many options out there to accomplish those kinds of things. So I was just curious of your general thoughts on that and where it’s headed. [00:05:43] CM: It’s fascinating to see the sort of burgeoning ecosystem around Kubernetes, and I think it’s heartening, because if you think at the very highest level, the world is going to go one of two ways with the introduction of the hyper-scale public cloud. It’s either going to lead us into a world which feels like mainframe era again, where no one ever got [inaudible 00:06:01] Amazon in this case, or by Microsoft, whatever the case. Whoever sort of merges over time as the dominant force. But it also represents some challenges where you have these vertically integrated closed systems, innovation becomes prohibitively difficult. It’s hard to innovate in a closed system, because you’re innovating only for organizations that have already taken that dependancy. I think Kubernetes has opened it up, not just in terms of the world of applications that can run Kubernetes, but also this burgeoning ecosystem of supporting technologies that can create value. There’s a reason why startups are building around Kubernetes. There’s a reason they’re looking to solve these problems. I do think we’ll see a continued period of consolidation. You're not a cool mainstream enterprise software provider if you don’t have a Kubernetes story today. I think we’ll start to see continued focus and consolidation around a set of the larger organizations that are operating in this space. It’s not accidental that Heptio is a part of VMware at this point. When I looked at the ecosystem, it was pretty clear we need to take a boat to fully materialize the value of Kubernetes and I am pleased to be part of this organization. So I do think you’ll start to see a variety of different vendors emerging with a pretty clear, well-defined opinions and relatively turnkey solutions that address the gamut of capabilities. One organization needs to get into Kubernetes. One of the things that delights me about Kubernetes is that if you are a sophisticated organization that is self-identifying as a software company, and this is sort of manifest in the internet space if you’re running a sort of hyper-scale internet service, you are kind of by definition a software company. You probably have the skills on hand to make great choices around what projects, follow the communities, identify when things are reaching point of critical mass. You’re running in a space where your system is relatively homogenous. You don’t have just the sort of massive gamut of workloads, a lot of dimension enterprise organizations have. There’s going to be different approaches to the ecosystem depending on which organization is looking at the problem space. I do think this is prohibitively challenging for a lot of organizations that are not resourced at the level of a hyper-scale internet company from a technology perspective, where their day job isn’t running a production service for millions or billions of users. I do think situations like that, it makes a tremendous amount of sense to identify and work with someone you trust in the ecosystem, that can help you just navigate the wild map that is the Kubernetes landscape, that can participate in a number of these emerging communities that has the ability to put their thumb on the scale where necessary to make sure that things converge. I think it’s situational. I think the lovely thing about Kubernetes is that it does give organizations a chance to cut their teeth without having to dig into like a deep procurement cyclewith a major vendor. We see a lot of self-service Kubernetes projects getting initiated. But at some point, almost inevitably, people need a little bit more help, and that’s the role of a lot of these vendors. I think that I truly hope that I’m personally committed to, is that as we start to see the convergence of this ecosystem, as we start to see the pieces falling into place, that we retain an emphasis on the value of community that we also sort of avoid the balkanization and fragmentation, which sometimes comes out of these types of systems. We are so much better served as a software company if we can preserve consistency from environment to environment. The reality is as we start looking at large organizations, enterprises that are consuming Kubernetes, it’s almost inevitable that they’re going to be consuming Kubernetes from a number of different sources. Whether the sources are cloud provider delivering Kubernetes services or whether they handle Kubernetes clusters that are dedicated centralized IT team is delivering or whether it’s vendor provided Kubernetes. There’s going to be a lot of different flavors and variants on it. I think working within the community not as king makers, but as concerned citizens that are looking to make sure that there are very high-levels of consistency from offering to offering, means that our customers are going to be better served. We’re right now in a time where this technology is burgeoning. It’s highly scrutinized, but it’s not necessarily very widely deployed. So I think it’s important to just keep an eye on that sort of community centricity. Stay as true to our stream as possible. Avoid balkanization, and I think everyone will benefit from that. [00:10:16] DC: Makes sense. One of the things I took away from my year, I was just looking kind of back at my year and learning, consolidating my thoughts on what had happened. One of the big takeaways for me in my customer engagements this year was that a number of customers outright came out explicitly and said, “Our success as a company is not going to be measured by our ability to operate Kubernetes, which is true and obvious.” But at the same time, I think that that’s a really interesting moment of awareness for a lot of the people that I work with out there in the field, where they realized, you know what, Kubernetes may be the next best thing. It may be an incredible technology, but fundamentally, it’s not going to be the measure by which we are graded success. It’s going to be what we do on top of that that is more interesting. So I think that your point about that ecosystem is large enough that people will be consuming Kubernetes for multiple searches is sort of amplified by that, because people are going to look for that easy button as inroad. They’re going to look for some way to get the Kubernetes thing so that they can actually start exploring what will happen on top of it as their primary goal rather than how to get Kubernetes from an operational perspective or even understand the care and feeding of it because they don’t see that as the primary measure of success. [00:11:33] CM: That is entirely true. When I think about enterprise software, there’s sort of these three pieces of it. The first piece is the sort of crystaline core of enterprise software. That’s consistent from enterprise to enterprise to enterprise. It’s purchased from primary vendors or it’s built by open source communities. It represents a significant basis for everything. There’s the sort of peripheral, the sort of sea of applications that exist around that enterprises built that are entirely unique to their environment, and they’re relatively fluid. Then there’s this weird sort of interstitial layer, which is the integration glue that exists between their crystalline core and those applications and operating practices that enterprises create. So I think from my side, we benefit if that crystalline core is as large as possible so that enterprises don’t have to rely on bespoke integration practices as much possible. We also need to make allowances for the idea that that interstitial layer between the sort of core of a technology like Kubernetes and the applications may be modular or sort of extended by a variety of different vendors. If you’re operating in this space, like the telco space, your problems are going to be unique to telco, but they’re going to be shared by every other telco provider. One of the beautiful things about Kubernetes is it is sufficiently modular, it is a pretty well-thought resistant. So I think we will start to see a lot of specialization in terms of those integration pieces. A lot of specialization in terms of how Kubernetes is fit to a specific area, and I think that represents an awful opportunity for the community to continue to evolve. But I also think it means that we as contributors to the project need to make allowances for that. We can’t hold opinion to the point where it precludes massive significant value for organizations as they look at modularized and extending the platform. [00:13:19] CC: What is your opinion on people making specialized Kubernetes operating systems? For example, we’re talking about telcos. I think there’s a Kubernetes OSS specifically for telcos that strip away things that kind of industry doesn’t need. What are the tradeoffs that you see? [00:13:39] CM: It’s almost inevitable that you’re going to start to see specialized operating system distributions that are tailored to container-based workloads. I think as we start looking at like the telco space with network function virtualization, Kubernetes promises to be something that we never really saw before. At the end of the day, telco is very broadly deployed open stack as this primary substrate for network function virtualization. But at the end of the day, they ended up not just deploying one rendition of open stack. But in many cases, three, four, five, depending on what functions they wanted to run, and there wasn’t a sufficient commonality in terms of the implementations. It became very sort of vendor-centric and balkanized in many ways. I think there’s an opportunity here to work hard as a community to drive convergence around a lot of those Kubernetes constructs so that, sure, the operating system is going to be different. If you’re running an NFV data plane implementation, doing a lot of bit slinging, it’s going to look fundamentally different to anything else in the industry, right? But that shouldn’t necessarily mean that you can’t use the same tools to organize, manage and reason about the workloads. A lot of the innovations that happen above that shouldn’t necessarily be tied to that. I think there’s promise there and it’s going to be an amazing test for Kubernetes itself to see how well it scales into those environments. By and large, I’m a fan of rendered down, container-optimized operating system distributions. There’s a lot of utility there, but I think we also need to be practical and recognize that enterprises have gotten comfortable with the OS landscape that they have. So we have to make allowances that as part of containerizing and distributing your application, maybe you don’t necessarily need to and hopefully re-qualify the underlying OS and challenge a lot of the assumptions. So I think we just need to pragmatic about it. [00:15:19] DC: I know that’s a dear topic to Josh and I. We’ve fought that battle in the past as well. I do think it’s another one of those things where it’s a set of assumptions. It’s fascinating to me how many different ecosystems are sort of collapsing, maybe not ecosystems. How many different audiences are brought together by a technology like container orchestration. That you are having that conversation with, “You know what? Let’s just change the paradigm for operating systems.” That you are having that conversation with, “Let’s change the paradigm for observability and lifecycle stuff. Let’s change the paradigm for packaging. We’ll call it containers.” You know what I mean? It’s so many big changes in one idea. It’s crazy. [00:15:54] CM: It’s a little daunting if you think about it, right? I always say, change is easiest across one dimension, right? If I’m going to change everything all at once across all the dimensions, life gets really hard. I think, again, it’s one of these things where Kubernetes represents a lot of value. I walk into a lot of customer accounts and I spend a lot of time with customers. I think based on their experiences, they sort of make one of two assumptions. There’s a set of vendors that will come into an environment and say, “Hey, just run this tool against your virtual machine images – and Kubernetes, right?” Then they have another set of vendors that will come in and say, “Yeah. Hey, you just need to go like turn this thing into 12 factor cloud native service mesh-linked applications driven through CICD, and your life is magic.” There are some cases where it makes sense, but there’re some cases where it just doesn’t. Hey, what uses a 24 gigabyte container? Is that really solving the problems that you have in some systematic way? At the other end of the spectrum, like there’s no world in which an enterprise organization is rewriting 3,000, 5,000 applications to be cloud native from the ground up. It just is not going to happen, right? So just understanding the return investment associated with the migration into Kubernetes. I’m not saying where it make sense and where it doesn’t. It’s such an important part of this story. [00:17:03] JR: On that front, and this is something Duffy and I talk to our customers about all the time. Say you’re sitting with someone and you’re talking about potentially using Kubernetes or they’re thinking about it, are there like some key indicators that you see, Craig, as like, “Okay. Maybe Kubernetes does have that return on investment pretty soon to justify it." Or maybe even in the reverse, like some things where you think, “Okay, these people are just going to implement Kubernetes and it’s going to become shelf weary.” How do you qualify as an org, “I might be ready to bring on something like Kubernetes.” [00:17:32] CM: It’s interesting. For me, it’s almost inevitably – as much about the human skills as anything else. I mean, the technology itself isn’t rocket science. I think the sort of critical success criteria, when I start looking at engagement, is there a cultural understanding of what Kubernetes represents? Kubernetes is not easy to use. That initial [inaudible 00:17:52] to the face is kind of painful for people that are used to different experiences. Making sure that the basic skills and expectations are met is really important. I think there’s definitely some sort of acid test around workloads fit as you start looking at Kubernetes. It’s an evolving ecosystem and it’s maturing pretty rapidly, but there are still areas that need a little bit more heavy lifting, right? So if you think about like, “Hey, I want to run a vertically-scaled OLTP database in Kubernetes today.” I don’t know. Maybe not the best choice. If the customer knows that, if they have enough familiarity or they’re willing to engage, I think it makes a tremendous amount of sense. By and large, the biggest challenge I see is not so much in the Kubernetes space. It’s easy enough to get to a basic cluster. There’re sort of two dimensions to this, there is day two operations. I see a lot of organizations that have worked to create scale up programs of platform technologies. Before Kubernetes there was Mesos and there’s obviously PCF that we’ll be coming more increasingly involved in. Organizations that have chewed on creating and deploying a standardized platform often have the operational skills, but you also need to look at like why did that previous technology really meet sort of criteria, and do you have the skills to operate it on a day two basis? Often there’s not – They’ve worked out the day two operational issues, but they still haven’t figured out like what it means to create a modern software supply chain that can deliver into the Kubernetes space. They haven’t figured out necessarily how to create the right incentive structures and experiences for the developers that are looking to build, package and deliver into that environment. That’s probably the biggest point of frustration I see with enterprises, is, “Okay. I got to Kubernetes. Now what?” That question just hasn’t been answered. They haven’t really thought through, “These are the CICD processes. This is how you engage your cyber team to qualify the platform for these classes of workloads. This is how you set up a container repo and run scans against it. This is how you assign TTL on images, so you don’t just get massive repo.” There’s so much in the application domain that just needs to exist that I think people often trivialize and it’s really taking the time and picking a couple of projects being measured in the investments. Making sure you have the right kind of cultural profile of teams that are engaged. Create that sort of celebratory moment of success. Make sure that the team is sort of metricking and communicating the productivity improvements, etc. That really drives the option and engagement with the whole customer base. [00:20:11] CC: It sounds to me like you have a book in the making. [00:20:13] CM: Oh! I will never write a book. It just seems like a lot of work. Brendan and a buch of my friends write books. Yeah, that seems like a whole lot of work. [00:20:22] DC: You had mentioned that you decided you wanted to work with Joe again. You formed Heptio. I was actually there for a year. I think I was around for a bit longer than that obviously. I’m curious what your thoughts about that were as an experiment win. If you just think about it as that part of the journey, do you think that was a success and what did you learn from that whole experiment that you wished everybody knew, just from a business perspective? It might have been business or it might have been running a company, any of that stuff. [00:20:45] CM: So I’m very happy with the way that Heptio went. There were a few things that sort of stood out for me as things that folks should think about if they’re going to start a startup or they want to join a startup. The first and foremost I would say is design the culture to the problem at hand. Culture isn’t accidental. I think that Heptio had a pretty distinct and nice culture, and I don’t want to sound self-congratulatory. I mean, as with anything, a certain amount of this is work, but a lot of it is luck as well. Making sure that the cultural identity of the company is well-suited to the problem at-hand. This is critical, right? When I think about what Heptio embodied, it was really tailored to the specific journey that we were setting ourselves up for. We were looking to be passionate advocates for Kubernetes. We were looking to walk the journey with our customers in an authentic way. We were looking to create a company that was built around sustainability. I think the culture is good and I encourage folks either the thing you’re starting is a startup or looking to join one, to think hard about that culture and how it’s going to map to the problems they’re trying to solve. The other thing that I think really motivated me to do Heptio, and I think this is something that I’m really excited to continue on with VMware, was the opportunity to walk the journey with customers. So many startups have this massive reticence to really engage deeply in professional services. In many ways, Google is fun. I had a blast there. It’s a great company to work for. We were able to build out some really cool tech and do good things. But I grew kind of tired of writing letters from the future. I was, “Okay, we are flying cars." When you're interacting with the customer. I can’t start my car and get to work. It’s great that you have flying cars, but right now I just need to get in my car, drive down the block and get out and get to work. So walking the journey with customers is probably the most important learning from Heptio and it’s one of the things I’m kind of most proud of. That opportunity to share the pain. Get involved from day one. Look at that as your most valuable apparatus to not just build your business, but also to learn what you need to build. Having a really smart set of people that are comfortable working directly with customers or invested in the success of those customers is so powerful. So if you’re in the business or in the startup game, investors may be leery of building out a significant professional service as a function, because that’s just how Silicon Valley works. But it is absolutely imperative in terms of your ability to engage with customers, particularly around nascent technologies, filled with gaps where the product doesn’t exist. Learn from those experiences and bring that back into the core product. It’s just a huge part of what we did. If I was ever in a situation where I had to advice a startup in the sort of open source space, I’d say lean into the professional service. Lean into field engineering. It’s a critical way to build your business. Learn what customers need. Walk the journey with them and just develop a deep empathy. [00:23:31] CC: With new technology, that was a concern about having enough professionals in the market who are knowledgeable in that new technology. There is always a gap for people to catch up with that. So I’m curious to know what customers or companies, prospective customers, how they are thinking in terms of finding professionals to help them? Are they’re concerned that there’s enough professionals in the market? Are they finding that the current people who are admins and operators are having an easy time because their skills are transferable, if they’re going to embark on the Kubernetes journey? What are they telling you? [00:24:13] CM: I mean, there’s a huge skills shortage. This is one of the kind of primary threats to the short term adoption of Kubernetes. I think Kubernetes will ultimately permeate enterprise organizations. I think it will become a standard for distributed systems development. Effectively emerging as an operating system for distributed systems, is people build more natively around Kubernetes. But right now it’s like the early days of Linux, where you deploy Linux, you’d have to kind of build it from scratch type of thing. It is definitely a challenge. For enterprise organizations, it’s interesting, because there’s a war for talent. There’s just this incredible appetite for Kubernetes talent. There’s always that old joke around the job description for like 10 years of Kubernetes experience on a five-year project. That certainly is something we see a lot. I’d take it from two sides. One is recognizing that as an enterprise organization, you are not going to be able to hire this talent. Just accept that sad truth. You can hire a seed crystal for it, but you really need to look at that as something that you’re going to build out as an enablement function for your own consumption. As you start assessing individuals that you’re going to bring on in that role, don’t just assess for Kubernetes talent. Assess for the ability to teach. Look for people that can come in and not just do, but teach and enable others to do it, right? Because at the end of the day, if you need like 50 Kubernauts at a certain level, so does your competitor and all of your other competitors. So does every other function out there. There’s just massive shortage of skills. So emphasizing your own – taking on the responsibility of building your own expertise. Educating your own organization. Finding ways to identify people that are motivated by this type of technology and creating space for them and recognizing and rewarding their work as they build this out. Because it’s far more practical to hire into existing skillset and then create space so that the people that have the appetite and capability to really absorb these types of disruptive technologies can do so within the parameters of your organization. Create the structures to support them and then make it their job to help permeate that knowledge and information into the organization. It’s just not something you can just bring in. The skills just don’t exist in the broader world. Then for professionals that are interested in Kubernetes, this is definitely a field that I think we’ll see a lot of job security for a very long-time. Taking on that effort, it’s just well worth the journey. Then I’d say the other piece of this is for vendors like VMware, our job can’t be just delivering skills and delivering technology. We need to think about our role as an enablers in the ecosystem as folks that are helping not just build up our own expertise of Kubernetes that we can represent to customers, but we’re well-served by our customers developing their own expertise. It’s not a threat to us. It actually enables them to consume the technologies that we provide. So focusing on that enablement through us as integration partners and [inaudible] community, focusing on enablement for our customers and education programs and the things that they need to start building out their capacity internally, is going to serve us all well. [00:27:22] JR: Something going back to maybe the Heptio conversation, I’m super interested in this. Being a very open source-oriented company, at VMware this is of course this true as well. We have to engage with large groups of humans from all different kinds of companies and we have to do that while building and shipping product to some degree. So where I’m going with this is like – I remember back in the Heptio days, there was something with dynamic audit logging that we were struggling with, and we needed it for some project we were working on. But we needed to get consensus in a designed approve at like a bigger community level. I do know to some degree that did limit our ability to ship quickly. So you probably know where I’m going with this. When you’re working on projects or products, how do you balance, making sure the whole community is coming along with you, but also making sure that you can actually ship something? [00:28:08] DM: That harkens back to that sort of catch phrase that Tim Sinclair always uses. If you want to go fast, go alone. If you want to go far, go together. I think as with almost everything in the world, these things are situational, right? There are situations where it is so critical that you bring the community along with you that you don’t find yourself carrying the load for something by yourself that you just have to accept and absorb that it’s going to be pushing string. Working with an engaged community necessitates consensus, necessitates buy-in not just from you, but from potentially your competitors. The people that you’re working with and recognizing that they’ll be doing their own sort of mental calculus around whether this advantages them or not and whatnot. But hopefully, I think certainly in the Kubernetes community, this is general recognition that making the underlying technology accessible. Making it ubiquitous, making it intrinsically supportable profits everyone. I think there’re a couple of things that I look at. Make the decision pretty early on as to whether this is something you want to kind of spark off and sort of stride off on your own an innovate around, whether it’s something that’s critical to bring the community along with you around. I’ll give you two examples of this, right? One example was the work we did around technologies like Valero, which is a backup restore product. It was an urgent and critical need to provide a sustainable way to back up and recover Kubernetes. So we didn’t have the time to do this through Kubernetes. But also it didn’t necessarily matter, because everything we’re doing was build this addendum to Kubernetes. That project created a lot of value and we’ve donated to open source project. Anyone can use it. But we took on the commitment to drive the development ourselves. It’s not just we need it to. Because we had to push very quickly in that space. Whereas if you look at the work that we’re doing around things like cluster API and the sort of broader provisioning of Kubernetes, it’s so important that the ecosystem avoids the tragedy of the commons around things like lifecycle management. It’s so important that we as a community converge on a consistent way to reason about the deployment upgrade and scaling of Kubernetes clusters. For any single vendor to try to do that by themselves, they’re going to take on the responsibility of dealing with not just one or two environments if you’re a hyperscale cloud provider [inaudible 00:30:27] many can do that. But we think about doing that for, in our case, “Hey, we only deploy into vSphere. Not just what’s coming next, but also earlier versions of vSphere. We need to be able to deploy into all of the hyper-scalers. We need to deploy into some of the emerging cloud providers. We need to start reasoning about edge. We need to start thinking about all of these. We’re a big company and we have a lot of engineers. But you’re going to get stretched very thin, very quickly if you try to chew that off by yourself. So I think a lot of it is situational. I think there are situations where it does pay for organizations to kind of innovate, charge off in a new direction. Run an experiment. See if it sticks. Over time, open that up to the community as it makes sense. The thing that I think is most important is that you just wear your heart on your sleeve. The worst thing you can do is to present a charter that, “Hey, we’re doing this as a community-centric, open project with open design, open community, open source,” and then change your mind later, because that just creates dramas. I think it’s situational. Pick the path that makes sense to the problem at-hand. Figure out how long your customer can wait for something. Sometimes you can bring things back to communities that are very open and accepting community. You can look at it as an experiment, and if it makes sense in that experiment perform factor, present it back to the Kubernetes communities and see if you can kind of get it back in. But in some case it just makes sense to work within the structure and constraints of the community and just accept that great things from a community angle take a lot of time. [00:31:51] CC: I think too, one additional thing that I don’t think was mentioned is that if a project grows too big, you can always break it off. I mean, Kubernetes is such a great example of that. Break it off into separate components. Break it off into separate governance groups, and then parts can move with different speeds. [00:32:09] CM: Yeah, and there’s all kinds of options. So the heart of it is no one rule, right? It’s entirely situational. What are you trying to accomplish on what arise and acknowledge and accept that the evolution of the core of Kubernetes is slowing as it should. That’s a signal that the project is maturing. You cannot deliver value at a longer timeline that your business or your customers can absorb then maybe it makes sense to do something on the outside. Just wear your heart on your sleeve and make sure your customers and your partners know what you’re doing. [00:32:36] DC: One of your earlier points about how do companies – I think Josh's question and was around how do companies attract talent. You’re basically pointing, and I think that there are some relation to this particular topic because, frequently, I’ve seen companies find some success by making room for open source or upstream engineers to focus on the Kubernetes piece and to help drive that adoption internally. So if you’re going to adopt something like a Kubernetes strategy as part of a larger company goal, if you can actually make room within your organization to bring people who are – or to support people who want to focus on that up stream, I think that you get a lot of ancillary benefits from that, including it makes it easier to adopt that technology and understand it and actually have some more skin in the game around where the open source project itself is going. [00:33:25] CM: Yeah, absolutely. I think one of the lovely things about the Kubernetes community is this idea of your position is earned, not granted, right? The way that you earn influence and leadership and basically the good will of everyone else in that community is by chopping wood, carrying water. Doing the things that are good for the community. Over time, any organization, any human being can become influential and lead based on their merits of their contributions. It’s important that vendors think about that. But at the same time, I have a hard time taking exception with practically any use of open source. At the end of the day, open source by its nature is a leap of faith. You’re making that technology accessible. If someone else can take it, operationalize it well and deliver value for organizations, that’s part of your contract. That’s what you absorb as a vendor when you start the thing. So people shouldn’t feel like they have to. But if you want to influence and lead, you do need to. Participate in these communities in an open way. [00:34:22] DC: When you were helping form the CNCF and some of those projects, did you foresee it being like a driving goal for people, not just vendors, but also like consumers of the technologies associated with those foundations? [00:34:34] CM: Yeah, it was interesting. Starting the CNCF, I can speak from the position of where I was inside Google. I was highly motivated by the success of Kubernetes. Not just personally motivated, because it was a project that I was working on. I was motivated to see it emerge as a standard for distributed systems development that attracts the way the infrastructure provider. I’m not ashamed of it. It was entirely self-serving. If you looked at Google’s market position at that time, if you looked at where we were as a hyper-scale cloud provider. Instituting something that enabled the intrinsic mobility of workloads and could shuffle around the cards on the deck so to speak [inaudible 00:35:09]. I also felt very privileged that that was our position, because we didn’t necessarily have to create artificial structures or constraints around the controls of the system, because that process of getting something to become ubiquitous, there’s a natural path if you approach it as a single provider. I’m not saying who couldn’t have succeeded with Kubernetes as a single provider. But if Red Hat and IBM and Microsoft and Amazon had all piled on to something else, it’s less obvious, right? It’s less obvious that Kubernetes would have gone as far as it did. So I was setting up CNCF, I was highly motivated by preserving the neutrality. Creating structures that separated the various sort of forms of governance. I always joke that at the time of creating CNCF, I was motivated by the way the U.S. Constitution is structured. Where you have these sort of different checks and balances. So I wanted to have something that would separate vendor interests from things that are maintaining taste on the discreet project. The sort of architecture integrity, and maintain separation from customer segments, so that you’d create the sort of natural self-balancing system. It was definitely in my thinking, and I think it worked out pretty well. Certainly not perfect, but it did lead down a path which I think has supported the success of the project a fair bit. [00:36:26] DC: So we talked a lot about Kubernetes. I’m curious, do you have some thoughts, Carlisia? [00:36:31] CC: Actually, I know you have a question about microliths. I was very interested in exploring that. [00:36:37] CM: There’s an interesting pattern that I see out there in the industry and this manifests in a lot of different ways, right? When you think about the process of bringing applications and workloads into Kubernetes, there’s this sort of pre-dispositional bias towards, “Hey, I’ve got this monolithic application. It’s vertically scaled. I’m having a hard time with the sort of team structure. So I’m going to start tuning it up into a set of microservices that I can then manage discretely and ideally evolve on a separate cadence. This is an example of a real customer situation where someone said, “Hey, I’ve just broken this monolith down into 27 microservices.” So I was sort of asking a couple of questions. The first one was when you have to update those 27 – if you want to update one of those, how many do you have to touch? The answer was 27. I was like, “Ha! You just created a microlith.” It’s like a monolith, except it’s just harder to live with. You’re taking a packaging problem and turn it into a massively complicated orchestration problem. I always use that jokingly, but there’s something real there, which is there’s a lot of secondary things you need to think through as you start progressing on this cloud native journey. In the case of microservice development, it’s one thing to have API separated microservices. That’s easy enough to institute. But instituting the organization controls around an API versioning strategy such you can start to establish stable API with consistent schema and being able to sort of manage the dependencies to consuming teams requires a level of sophistication that a lot of organizations haven’t necessarily thought through. So it’s very easy to just sort of get caught up in the hype without necessarily thinking through what happens downstream. It’s funny. I see the same thing in functions, right? I interact with organizations and they’re like, “Wow! We took this thing that was running in a container and we turned it into 15 different functions.” I’m like, “Ha! Okay.” You start asking questions like, “Well, do you have any challenges with state coherency?” They’re like, “Yeah! It’s funny you say that. Because these things are a little bit less transactionally coherent, we have to write state watches. So we try and sort of watermark state and watch this thing." I’m like, “You’re building a distributed transaction coordinator on your free time. Is this really the best use of your resources?" Right? So it really gets back to that idea that there’s a different tool for a different job. Sometimes the tool is a virtual machine. Sometimes it’s not. Sometimes the tool is a bare metal deployment. If you’re building a quantitative trading application that’s microsecond latency sensitive, you probably don’t want to hypervisor there. Sometimes a VM is the natural destination and there’s no reason to move from a VM. Sometimes it’s a container. Sometimes you want to start looking at that container and just modularizing it so you can run a set of things next to each other in the same process space. Sometimes you’re going to want to put APIs between those things and separate them out into separate containers. There’s an ROI. There’s a cause and there’s a benefit associated with each of those transitions. More importantly, there are a set of skills that you have to have as you start looking at their continuum and making sure that you’re making good choices and being wise about it. [00:39:36] CC: That is a very good observation. Design is such an important part of software development. I wonder if Kubernetes helps mask these design problems. For example, the ones you are mentioning, or does Kubernetes sort of surfaces them even more? [00:39:53] CM: It’s an interesting philosophical question. Kubernetes certainly masks some problems. I ran into an early – this is like years ago. I ran into an early customer, who confided in me, "I think we’re writing worse code now." I was like, ”What do you mean?” He was like, “Well, it used to be when we went out of memory on something, we get paged. Now we’ve set out that we go and it just restarts the container and everything continuous.” There’s no real incentive for the engineers to actually go back and deal with the underlying issues and recourse it, because the system is just more intrinsically robust and self-healing by nature. I think there's definitely some problems that Kubernetes will compound. If you’re very sloppy with your dependencies, if you create a really large, vertically scaled monolith that’s running at VM today, putting it in a container is probably strictly going to make your life worse. Just be respectful of that. But at the same time, I do think that the discipline associated with transition to Kubernetes, if you walk it a little bit further along. If you start thinking about the fact that you’re not running a lot of imperative processes during a production in a push, where deployment container is effectively a bin copy with some minimal post-deployment configuration changes that happen. It sort of leads you on to a much happier path naturally. I think it can mask some issues, but by and large, the types of systems you end up building are going to be more intrinsically operationally stable and scalable. But it is also worth recognizing that it’s — you are going to encounter corner cases. I’ve run into a lot of customers that will push the envelope in a direction that was unanticipated by the community or they accidentally find themselves on new ground that’s just unstable, because the technology is relatively nascent. So just recognizing that if you’re going to walk down a new path, I’m not saying don’t, just recognize that you’re probably going to encounter some stuff that’s going to take over to working through. [00:41:41] DC: We get an earlier episode about API contracts, which I think highlights some of these stuff as well, because it sort of gets into some of those sharp edges of like why some of those things are super important when you start thinking about microservices and stuff. We’re coming to the end of our time, but one of the last questions I want to ask you, we’ve talked a lot about Kubernetes in this episode, I’m curious what the future holds. We see a lot of really interesting things happening in the ecosystem around moving more towards serverless. There are a lot of people who are like — thinking that perhaps a better line would be to move away from like infrastructure offering and just basically allow cloud providers in this stuff to manage your nodes for you. We have a few shots on goal for that ourselves. It’s been really an interesting evolution over the last year in that space. I’m curious, what sort of lifetime would you ascribe to it today? What do you think that this is going to be the thing in 10 years? Do you think it will be a thing in 5 years? What do you see coming that might change it? [00:42:32] CM: It’s interesting. Well, first of all, I think 2018 was the largest year ever for mainframe sales. So we have these technologies, once they’re in enterprise, it tends to be pretty durable. The duty cycle of enterprise software technology is pretty long-lived. The real question is we’ve seen a lot of technologies in this space emerge, ascend, reach a point of critical mass and then fade and they’re disrupted by the technologies. Is Kubernetes going to be a Linux or is Kubernetes going to be a Mesos, right? I mean, I don’t claim to know the answer. My belief, and I think this is probably true, is that it’s more like a Linux. When you think about the heart of what Kubernetes is doing, is it’s just providing a better way to build and organized distributed systems. I’m sure that the code will evolve rapidly and I’m sure there will be a lot of continued innovation enhancement. But when you start thinking about the fact that what Kubernetes has really done is brought controller reconciler based management to distributed systems developed everywhere. When you think about the fact that pretty much every system these days is distributed by nature, it really needs something that supports that model. So I think we will see Kubernetes sticking. We’ll see it become richer. We’ll start to see it becoming more applicable for a lot of things that we’re starting to just running in VMs. It may well continue to run in VMs and just be managed by Kubernetes. I don’t have an opinion about how to reason about the underlying OS and virtualization structure. The thing I do have opinion about is it makes a ton of sense to be able to use a declarative framework. Use a set of well-structured controllers and reconcilers to drive your world into a non-desired state. I think that pattern will be – it’s been quite successful. It can be quite durable. I think we’ll start to see organizations embrace a lot of these technologies over time. It is possible that something brighter, shinier, newer, comes along. Anyone will tell you that we made enough mistakes during the journey and there is stuff that I think everyone regret some of the Kubernetes train. I do think it’s likely to be pretty durable. I don’t think it’s a silver bullet. Nothing is, right? It’s like any of these technologies, there’s always the cost and there’s a benefit associated with it. The benefits are relatively well-understood. But there’s going to be different tools to do different jobs. There’s going to be new patterns that emerge that simplify things. Is Kubernetes the best framework for running functions? I don’t know. Maybe. Kind of like what the [inaudible] people are doing. But are there more intrinsically optimal ways to do this, maybe. I don’t know. [00:45:02] JR: It has been interesting watching Kubernetes itself evolve in that moving target. Some of the other technologies I’ve seen kind of stagnate on their one solution and don’t grow further. But that’s definitely not what I see within this community. It’s like always coming up with something new. Anyway, thank you very much for your time. That was an incredible session. [00:45:22] CM: Yeah. Thank you. It’s always fun to chat. [00:45:24] CC: Yeah. We’ll definitely have you back, Craig. Yes, we are coming up at the end, but I do want to ask if you have any thoughts that you haven’t brought up or we haven’t brought up that you’d like to share with the audience of this podcast. [00:45:39] CM: I guess the one thing that was going through my head earlier I didn’t say which is as you look at these technologies, there’s sort of these two duty cycles. There’s the hype duty cycle, where technology ascends in awareness and everyone looks at it as an answer to all the everythings. Then there’s the readiness duty cycle, which is sometimes offset. I do think we’re certainly peak hype right now in Kubernetes if you attended KubeCon. I do think there’s perhaps a gap between the promise and the reality for a lot of organizations. It's always just council caution and just be judicious about how you approach this. It’s a very powerful technology and I see a very bright future for it. Thanks for your time. [00:46:17] CC: Really, thank you so much. It’s so refreshing to hear from you. You have great thoughts. With that, thank you very much. We will see you next week. [00:46:28] JR: Thanks, everybody.

Welcome back. This is Episode 12, and we are going to talk about distributed systems without a degree or even with a degree, because who knows how much we learn in university. I am Carlisia Campos, one of your hosts. Today, I also have Duffie Cooley. Say hi, Duffie. [00:01:02] DC: Hey, everybody. [00:01:03] CC: And a new host for you, and this is such a treat. Michael Gasch, please tell us a little bit of your background. [00:01:11] MG: Hey! Hey, everyone! Thanks, Carlisia. Yes. So I’m new to the show. I just want to keep it brief because I think over the show we’ll discuss our backgrounds a little bit further. So right now, I’m with VMware. So I’ve been with VMware almost for five years. Currently, I'm in the office of the CTO. I’m a platform architect in the office of the CTO and I mainly use Kubernetes on a daily basis from an engineering perspective. So we build a lot of prototypes based on customer input or ideas that we have, and we work with different engineering teams. Kurbernetes has become kind of my bread and butter but lately more from a consumer perspective like developing with Kurbenetes or against Kubernetes, instead of the formal ware of mostly being around implementing and architecting Kubernetes. [00:01:55] CC: Nice. Very impressive. Duffie? [00:01:58] MG: Thank you. [00:01:59] DC: Yeah. [00:02:00] CC: Let’s give the audience a little bit of your backgrounds. We’ve done this before but just to frame the episodes, so people will know how we come in as distributed systems. [00:02:13] DC: Sure. In my experience, I spent – I don’t have a formal education history. I spent most of my time kind of like in a high school time. Then from there, basically worked into different systems administration, network administration, network architect, and up into virtualization and now containerization. So I’ve got a pretty hands-on kind of bootstrap experience around managing infrastructure, both at small-scale, inside of offices, and the way up to very large scale, working for some of the larger companies here in the Silicon Valley. [00:02:46] CC: All right. My turn I guess. So I do have a computer science degree but I don’t feel that I really went deep at all in distributed systems. My degree is also from a long time ago. So mainly, what I do know now is almost entirely from hands-on work experience. Even so, I think I'm very much lacking and I’m very interested in this episode, because we are going to go through some great resources that I am also going to check out later. So let’s get this party started. [00:03:22] DC: Awesome. So you want to just talk about kind of the general ideas behind distributed systems and like how you became introduced to them or like where you started in that journey? [00:03:32] CC: Yeah. Let’s do that. [00:03:35] DC: My first experience with the idea of distributed systems was in using them before I knew that they were distributed systems, right? One of the very first distributed systems as I look back on it that I ever actually spent any real time with was DNS, which I consider to be something of a distributed system. If you think about it, they have name servers, they have a bunch of caching servers. They solve many of the same sorts of problems. In a previous episode, we talked about how networking, just the general idea of networking and handling large-scale architecting networks. It’s also in a way very – has a lot of analogues into distributed systems. For me, I think working with and helping solve the problems that are associated with them over time gave me a good foundational understanding for when we were doing distributed systems as a thing later on in my career. [00:04:25] CC: You said something that caught my interest, and it’s very interesting, because obviously for people who have been writing algorithms, writing papers about distributed systems, they’re going to go yawning right now, because I’m going to say the obvious. As you start your journey programming, you read job requirements. You read or you must – should know distributed systems. Then I go, “What is distributed system? What do they really mean?” Because, yes, we understand apps stuck to apps and then there is API, but there’s always for me at least a question at the back of my head. Is that all there is to it? It sounds like it should be a lot more involved and complex and complicated than just having an app stuck on another app. In fact, it is because there are so many concepts and problems involved in distributed systems, right? From timing, clock, and sequence, and networking, and failures, how do you recover. There is a whole world in how do you log this properly, how do you monitor. There’s a whole world that revolves around this concept of systems residing in different places and [inaudible 00:05:34] each other. [00:05:37] DC: I think you made a very good point. I think this is sort of like there’s an analog to this in containers, oddly enough. When people say, “I want a container within and then the orchestration systems,” they think that that's just a thing that you can ask for. That you get a container and inside of that is going to be your file system and it’s going to do all those things. In a way, I feel like that same confusion is definitely related to distributed systems. When people are interacting with distributed systems today or if I were to ask like 50 people what a distributed system is, I would probably get 50 different answers. I think that you got a pretty concise definition there in that it is a set of systems that intercommunicate to perform some function. It’s like found at its base line. I feel like that's a pretty reasonable definition of what distributed systems are, and then we can figure out from there like what functions are they trying to achieve and what are some of the problems that we’re trying to solve with them. [00:06:29] CC: Yeah. That’s what it’s all about in my head is solving the problems because at the beginning, I was thinking, “Well, it must be just about communicating and making things work.” It’s the opposite of that. It’s like that’s a given. When a job says you need to understand about distributed systems, what they are really saying is you need to know how to deal with failures, not just to make it work. Make it work is sort of the easy part, but the whole world of where the failures can happen, how do you handle it, and that, to me is what needing to know distributed system comes in handy. In a couple different things, like at the top layer or 5% is knowing how to make things work, and 95% is knowing how to handle things when they don’t work, because it’s inevitable. [00:07:19] DC: Yeah, I agree. What do you think, Michael? How would you describe the context around distributed systems? What was the first one that you worked with? [00:07:27] MG: Exactly. It’s kind of similar to your background, Duffie, which is no formal degree or education on computer science right after high school and jumping into kind of my first job, working with computers, computer administration. I must say that from the age of I think seven or so, I was interested in computers and all that stuff but more from a hardware perspective, less from a software development perspective. So my take always was on disassembling the pieces and building my own computers than writing programs. In the early days, that just was me. So I completely almost missed the whole education and principles and fundamentals of how you would write a program for a single computer and then obviously also for how to write programs that run across a network of computers. So over time, as I progress on my career, especially kind of in the first job, which was like seven years of different Linux systems, Linux administrations, I kind of – Like you, Duffie, I dealt with distributed systems without necessarily knowing that I'm dealing with distributed systems. I knew that it was mostly storage systems, Linux file servers, but distributed file servers. Samba, if some of you recall that project. So I knew that things could fail. I know it could fail, for example, or I know it could not be writable, and so a client must be stuck but not necessarily I think directly related to fundamentals of how distributed systems work or don’t work. Over time, and this is really why I appreciate the Kubernetes project in community, I got more questions, especially when this whole container movement came up. I got so many questions around how does that thing work. How does scheduling work? Because scheduling kind of was close to my interest in the hardware design and low-level details. But I was looking at Kubernetes like, “Okay. There is the scheduler.” In the beginning, the documentation was pretty scarce around the implementation and all the control as for what’s going on. So I had to – I listen to a lot of podcasts and Brian Grant’s great talks and different shows that he gave from the Kubernetes space and other people there as well. In the end, I had more questions than answers. So I had to dig deeper. Eventually, that led me to a path of wanting to understand more formal theory behind distributed systems by reading the papers, reading books, taking some online classes just to get a basic understanding of those issues. So I got interested in results scheduling in distributed systems and consensus. So those were two areas that kind of caught my eyes like, “What is it? How do machines agree in a distributed system if so many things can go wrong?” Maybe we can explore this later on. So I’m going to park this for a bit. But back to your question, which was kind of a long-winded answer or a road to answering your question, Duffie. For me, a distributed system is like this kind of coherent network of computer machines that from the outside to an end-user or to another client looks like one gigantic big machine that is [inaudible 00:10:31] to run as fast. That is performing also efficient. It constitutes a lot of characteristics and properties that we want from our systems that a single machine usually can’t handle. But it looks like it's a big single machine to a client. [00:10:46] DC: I think that – I mean, it is interesting like, I don’t want to get into – I guess this is probably not just a distributed systems talk. But obviously, one of the questions that falls out for me when I hear that answer is then what is the difference between a micro service architecture and distributed systems, because I think it's – I mean, to your point, the way that a lot of people work with the app to learn to develop software, it’s like we’re going to develop a monolithic application just by nature. We’re going to solve a software problem using code. Then later on, when we decide to actually scale this thing or understand how to better operate it under a significant load, then we started thinking about, “Okay. Well, how do we have to architect this differently in such a way that it can support that load?” That’s where I feel like the beams cut across, right? We’re suddenly in a world where you’re not only just talking about microservices. You’re also talking about distributed systems because you’re going to start thinking about how to understand transactionality throughout that system, how to understand all of those consensus things that you're referring to. How do they affect it when I add mister network in there? That’s cool. [00:11:55] MG: Just one comment on this, Duffie, which took me a very long time to realize, which is coming – From my definition of what a distributed system is like this group of machines that they perform work in a certain sense or maybe even more abstracted like at a bunch of computers network together. What I kind of missed most of the time, and this goes back to the DNS example that you gave in the beginning, was the client or the clients are also part of this distributed system, because they might have caches, especially in DNS. So you always deal with this kind of state that is distributed everywhere. Maybe you don't even know where it kind of is distributed, and the client kind of works with a local stale data. So that is also part of a distributed system, and something I want to give credit to the Kafka community and some of the engineers on Kafka, because there was a great talk lately that I heard. It’s like, “Right. The client is also part of your distributed system, even though usually we think it's just the server. That those many server machines, all those microservices.” At least I missed that a long time. [00:12:58] DC: You should put a link to that talk in our [inaudible 00:13:00]. That would be awesome. It sounds great. So what do you think, Carlisia? [00:13:08] CC: Well, one thing that I wanted to mention is that Michael was saying how he’s been self-teaching distributed systems, and I think if we want to be competent in the area, we have to do that. I’m saying this to myself even. It’s very refreshing when you read a book or you read a paper and you really understand the fundamentals of an aspect of distributed system. A lot of things fall into place in your hands. I’m saying this because even prioritizing reading about and learning about the fundamentals is really hard for me, because you have your life. You have things to do. You have the minutiae in things to get done. But so many times, I struggle. In the rare occasions where I go, “Okay. Let me just learn this stuff trial and error,” it makes such a difference. Then once you learn, it stays with you forever. So it’s really good. It’s so refreshing to read a paper and understand things at a different level, and that is what this episode is. I don’t know if this is the time to jump in into, “So there are our recommendations.” I don't know how deep, Michael, you’re going to go. You have a ton of things listed. Everything we mention on the show is going to be on our website, on the show notes. So nobody needs to be necessarily taking notes. Anything thing I wanted to say is it would be lovely if people would get back to us once you listened to this. Let us know if you want to add anything to this list. It would be awesome. We can even add it to this list later and give a shout out to you. So it’d be great. [00:14:53] MG: Right. I don’t want to cover this whole list. I just wanted to be as complete as possible about a stuff that I kind of read or watched. So I just put it in and I just picked some highlights there if you want. [00:15:05] CC: Yeah. Go for it. [00:15:06] MG: Yeah. Okay. Perfect. Honestly, even though not the first in the list, but the first thing that I read, so maybe from kind of my history of how I approach things, was searching for how do computers work and what are some of the issues and how do computers and machines agree. Obviously, the classic paper that I read was the Lamport paper on “Time, Clocks, and the Ordering of Events in a Distributed System”. I want to be honest. First time I read it, I didn’t really get the full essence of the paper, because it doesn't prove in there. The mathematic proof for me didn't click immediately, and there were so many things and concepts and physics and time that were thrown at me where I was looking for answers and I had more questions than answers. But this is not to Leslie. This is more like by the time I just wasn't prepared for how deep the rabbit hole goes. So I thought, if someone asked me for – I only have time to read one book out of this huge list that I have there and all the other resources. Which one would it be? Which one would I recommend? I would recommend Designing Data-Intensive Apps by Martin Kleppmann, which I’ve been following his blog posts and some partial releases that he's done before fully releasing that book, which took him more than four years to release that book. It’s kind of almost the Bible, state-of-the-art Bible when it comes to all concepts in distributed systems. Obviously, consensus, network failures, and all that stuff but then also leading into modern data streaming, data platform architectures inspired by, for example, LinkedIn and other communities. So that would be the book that I would recommend to someone if – Who does have time to read one book. [00:16:52] DC: That’s a neat approach. I like the idea of like if you had one thing, if you have one way to help somebody ramp on distributed systems and stuff, what would it be? For me, it’s actually I don't think I would recommend a book, oddly enough. I feel like I would actually – I’d probably drive them toward the kind of project, like the kind [inaudible 00:17:09] project and say, “This is a distributed system all but itself.” Start tearing it apart to pieces and seeing how they work and breaking them and then exploring and kind of just playing with the parts. You can do a lot of really interesting things. This is actually another book in your list that was written by Brendan Burns about Designing Distributed Systems I think it’s called. That book, I think he actually uses Kubernetes as a model for how to go about achieving these things, which I think is incredibly valuable, because it really gets into some of the more stable distributed systems patterns that are around. I feel like that's a great entry point. So if I had one thing, if I had to pick one way to help somebody or to push somebody in the direction of trying to learn distributed systems, I would say identify those distributed systems that maybe you’re already aware of and really explore how they work and what the problems with them are and how they went about solving those problems. Really dig into the idea of it. It’s something you could put your hands on and play with. I mean, Kubernetes is a great example of this, and this is actually why I referred to it. [00:18:19] CC: The way that works for me when I’m learning something like that is to really think about where the boundaries are, where the limitations are, where the tradeoffs are. If you can take a smaller system, maybe something like The Kind Project and identify what those things are. If you can’t, then ask around. Ask someone. Google it. I don’t know. Maybe it will be a good episode topic for us to do that. This part is doing this to map things out. So maybe we can understand better and help people understand things better. So mainly like yeah. They try to do the distributed system thesis are. But for people who don’t even know what they could be, it’s harder to identify it. I don’t know what a good strategy for that would be, because you can read about distributed systems and then you can go and look at a project. How do you map the concept to learning to what you’re seeing in the code base? For me, that’s the hardest thing. [00:19:26] MG: Exactly. Something that kind of I had related experience was like when I went into software development, without having formal education on algorithms and data structures, sometimes in your head, you have the problem statement and you're like, “Okay. I would do it like that.” But you don't know the word that describes, for example, a heap structure or queue because you’ve never – Someone told you that is heap, that is a queue, and/or that is a stick. So, for me, reading the book was a bit easier. Even though I have done distributed systems, if you will, administration for many years, many years ago, I didn't realize that it was a distributed system because I never had this definition or I never had those failure scenarios in mind and it never had a word for consensus. So how would I search for something like how do machines agree? I mean, if you put that on Google, then likely they will come – Have a lot of stuff. But if you put it in consensus algorithm, likely you get a good hit on what the answer should be. [00:20:29] CC: It is really problematic when we don't know the names of things because – What you said is so right, because we are probably doing a lot of distributed systems without even knowing that that’s what it is. Then we go in the job interview, and people are, “Oh! Have you done a distributed system?” No. You have but you just don’t know how to name things. But that’s one – [00:20:51] DC: Yeah, exactly. [00:20:52] CC: Yeah. Right? That’s one issue. Another issue, which is a bigger issue though is at least that’s how it is for me. I don’t want to speak for anybody else but for me definitely. If I can’t name things and I face a problem and I solve it, every time I face that problem it’s a one-off thing because I can’t map to a higher concept. So every time I face that problem, it’s like, “Oh!” It’s not like, “Oh, yeah!” If this is this kind of problem, I have a pattern. I’m going to use that to this problem. So that’s what I’m saying. Once you learn the concept, you need to be able to name it. Then you can map that concept to problems you have. All of a sudden, if you have like three things [inaudible 00:21:35] use to solve this problem, because as you work with computers, coding, it’s like you see the same thing over and over again. But when you don’t understand the fundamentals, things are just like – It’s a bunch of different one-offs. It’s like when you have an argument with your spouse or girlfriend or boyfriend. Sometimes, it’s like you’re arguing 10 times in a month and you thought, “Oh! I had 10 arguments.” But if you’d stop and think about it, no. We had one argument 10 times. It’s very different than having 10 problems versus having 1 problem 10 times, if that makes sense. [00:22:12] MG: It does. [00:22:11] DC: I think it does, right? [00:22:12] MG: I just want to agree. [00:22:16] DC: I think it does make sense. I think it’s interesting. You’ve highlighted kind of an interesting pattern around the way that people learn, which I think is really interesting. That is like some people are able to read about patterns or software patterns or algorithms or architectures and have that suddenly be an index of their heads. They can actually then later on correlate what they've read with the experience that they’re having around the things they're working on. For some, it needs to be hands-on. They need to actually be able to explore that idea and understand and manipulate it and be able to describe how it works or functions in person, in reality. They need to have that hands-on like, “I need to touch it to understand it,” kind of experience. Those people also, as they go through those experiences, start building this index of patterns or algorithms in their head. They have this thing that they can correlate to, right, like, “Oh! This is a time problem,” or, “This is a consensus problem,” or what have you, right? [00:23:19] CC: Exactly. [00:23:19] DC: You may not know the word for that saying but you're still going to develop a pattern in your mind like the ability to correlate this particular problem with some pattern that you’ve seen before. What's interesting is I feel like people have taken different approaches to building that index, right? For me, it’s been troubleshooting. Somebody gives me a hard problem, and I dig into it and I figure out what the problem is, regardless of whether it's to do with distributed systems or cooking. It could be anything, but I always want to get right in there and figure out what that problem and start building a map in my mind of all of the players that are involved. For others, I feel like with an educational background, if you have an education background, I think that sometimes you end up coming to this with a set of patterns already instilled that you understand and you're just trying to apply those patterns to the experience you’re having instead. It’s just very – It’s like horse before the cart or cart before the horse. It’s very interesting when you think about it. [00:24:21] CC: Yes. [00:24:22] MG: The recommendation that I just want to give to people that are like me who like reading is that I went overboard a bit in the beginnings because I was so fascinated by all the stuff, and it went down the rabbit hole deeper, deeper, deeper, deeper. Reading and reading and reading. At some point, even coming to weird YouTube channels that talk about like, “Is time real and where does time emerge from?” It became philosophical even like the past where I went to. Now, the thing is, and this is why I like Duffie’s approach with like breaking things and then undergo like trying to break things and understanding how they work and how they can fail is that immediately you practice. You’re hands-on. So that would be my advice to people who are more like me who are fascinated by reading and all the theory that your brain and your mind is not really capable of kind of absorbing all the stuff and then remembering without practicing. Practicing can be breaking things or installing things or administrating things or even writing software. But for me, that was also a late realization that I should have maybe started doing things earlier than the time I spent reading. [00:25:32] CC: By doing, you mean, hands-on? [00:25:35] MG: Yeah. [00:25:35] CC: Anything specific that you would have started with? [00:25:38] MG: Yes. On Kubernetes – So going back those 15 years to my early days of Linux and Samba, which is a project. By the time, I think it was written in C or C++. But the problem was I wasn’t able to read the code. So the only thing that I had by then was some mailing lists and asking questions and not even knowing which questions to ask because of lack of words of understanding. Now, fast-forward into Kubernetes’ time, which got me deeper in distributed systems, I still couldn't read the code because I didn't know [inaudible 00:26:10]. But I forced myself to read the code, which helped a little bit for myself to understand what was going on because the documentation by then was lacking. These days, it’s easier, because you can just install [inaudible 00:26:20] way easier today. The hands-on piece, I mean. [00:26:23] CC: You said something interesting, Michael, and I have given this advice before because I use this practice all the time. It's so important to have a vocabulary. Like you just said, I didn't know what to ask because I didn’t know the words. I practice this all the time. To people who are in this position of distributed systems or whatever it is or something more specific that you are trying to learn, try to expose yourself to the words, because our brains are amazing. Once you get exposure, it’s like your brain works in the background. All of a sudden, you go, “Oh, yeah! I know this word.” So podcasts are great for me. If I don't know something, I will look for a podcast on the subject and I start listening to it. As the words get repeated, just contextually. I don’t have to go and get a degree or anything. Just by listening to the words being spoken in context, absorb the meaning of it. So podcasting is great or YouTube or anything that you can listen. Just in reading too, of course. The best thing is talking to people. But, again, it’s really – Sometimes, it’s not trivial to put yourself in positions where people are discussing these things. [00:27:38] DC: There are actually a number of Meetups here in the Bay Area, and there’s a number of Meetups – That whole Meetup thing is sort of nationwide across the entire US and around the world it seems like now lately. Those Meetups I feel like there are a number of Meetups in different subject areas. There’s one here in the Bay Area called Papers We Love, where they actually do explore interesting technical papers, which are obviously a great place to learn the words for things, right? This is actually where those words are being defined, right? When you get into the consensus stuff, they really get into – One even is Raft. There are many papers on Raft and many papers on multiple things that get into consensus. So definitely, whether you explore a meetup on a distributed system or in a particular application or in a particular theme like Kubernetes, those things are great places just to kind of get more exposure to what people are thinking about in these problems. [00:28:31] CC: That is such a great tip. [00:28:34] MG: Yeah. The podcast is twice as good as well, because for people, non-natives – English speaker, I mean. Oh, people. Not speakers. People. The thing is that the word you’re looking for might be totally different than the English word. For example, consensus in Germany has this totally different meaning. So if I would look that up in German, likely I would find nothing or not really related at all. So you have to go through translation and then finding the stuff. So what you said, Duffie, with PWL, Papers We Love, or podcasts, those words, often they are in English, those podcasts and they are natural consensus or charting or partitioning. Those are the words that you can at least look up like what does it mean. That’s what I did as well thus far. [00:29:16] CC: Yes. I also wanted to do a plus one for Papers We Love. It’s – They are everywhere and they also have an online. They have an online version of the Papers We Love Meetup, and a lot of the local ones film their meetups. So you can go through the history and see if they talked about any paper that you are interested in. Probably, I’m sure multiple locations talk about the same paper, so you can get different takes too. It’s really, really cool. Sometimes, it’s completely obscure like, “I didn’t get a word of what they were saying. Not one. What am I doing here?” But sometimes, they talk about things. You at least know what the thing is and you get like 10% of it. But some paper you don’t. People who deal with papers day in and day out, it’s very much – I don’t know. [00:30:07] DC: It’s super easy when going through a paper like that to have the imposter syndrome wash over you, right, because you’re like – [00:30:13] CC: Yes. Thank you. That’s what I wanted to say. [00:30:15] DC: I feel like I’ve been in this for 20 years. I probably know a few things, right. But in talking about reading this consensus paper going, “Can I buy a vowel? What is happening?” [00:30:24] CC: Yeah. Can I buy a vowel? That’s awesome, Duffie. [00:30:28] DC: But the other piece I want to call out to your point, which I think is important is that some people don't want to go out and be there in person. They don’t feel comfortable or safe exploring those things in person. So there are tons of resources like you have just pointed out like the online version of Papers We Love. You can also sign into Slack and just interact with people via text messaging, right? There’s a lot of really great resources out there for people of all types, including the amount of time that you have. [00:30:53] CC: For Papers We Love, it’s like going to language class. If you go and take a class in Italian, your first day, even though that is going to be super basic, you’re going to be like, “What?” You’ll go back in your third week. You start, “Oh! I’m getting this.” Then a month, three months, “Oh! I’m starting to be competent.” So you go once. You’re going to feel lost and experience imposter syndrome. But you keep going, because that is a format. First, you start absorbing what the format is, and that helps you understand the content. So once your mind absorbs the format, you’re like, “Okay. Now, I have – I know how to navigate this. I know what’s coming next.” So you don’t have to focus on that. You start focusing in the content. Then little but little, you become more proficient in understanding. Very soon, you’re going to be willing to write a paper. I’m not there yet. [00:31:51] DC: That’s awesome. [00:31:52] CC: At least that’s how I think it goes. I don’t know. [00:31:54] MG: I agree. [00:31:55] DC: It’s also changed over time. It’s fascinating. If you read papers from like 20 years ago and you read papers that are written more recently, it's interesting. The papers have changed their language when considering competition. When you're introducing a new idea with a paper, frequently that you are introducing it into a market full of competition. You're being very careful about the language, almost in a way to complicate the idea rather than to make it clear, which is challenging. There are definitely some papers that I’ve read where I was like, “Why are you using so many words to describe this simple idea?” It makes no sense, but yeah. [00:32:37] CC: I don’t want to make this episode all about Papers We Love. It was so good that you mentioned that, Duffie. It’s really good to be in a room where we’ll be watching something online where you see people asking questions and people go, “Oh! Why is this thing like this? Why is X like this,” or, “Why is Y doing like this?” Then you go, “Oh! I didn’t even think that X was important. I didn’t even know that Y was important.” So you stop picking up what the important things are, and that’s what makes it click is now you’ve – Hooking into the important concepts because people who know more than you are pointing out and asking questions. So you start paying attention to learning what the main things it should be paying attention to, which is different from reading the paper by yourself. It’s just a ton of content that you need to sort through. [00:33:34] DC: Yeah. I frequently self-describe it as a perspective junkie, because I feel like for any of us really to learn more about a subject that we feel we understand, we need the perspective of others to really engage, to expand our understanding of that thing. I feel like and I know how to make a peanut butter and jelly sandwich. I’ve done it a million times. It’s a solid thing. But then I watch my kid do it and I’m like, “I hadn’t thought of that problem.” [inaudible 00:33:59], right? This is a great example of that. Those communities like Papers We Love are great opportunity to understand the perspective of others around these hard ideas. When we’re trying to understand complex things like distributed systems, this is where it’s at. This is actually how we go about achieving this. There is a lot that you can do on your own but there is always going to be more that you can do together, right? You can always do more. You can always understand this idea faster. You can understand the complexity of a system and how to break it down into these things by exploiting it with other people. That's I feel like – [00:34:40] CC: That is so well said, so well said, and it’s the reason for this show to exist, right? We come on a show and we give our perspectives, and people get to learn from people with different backgrounds, what their takes are on distributed systems, cloud native. So this was such a major plug for the show. Keep coming back. You’re going to learn a ton. Also, it was funny that you – It was the second time you mentioned cooking, made a cooking reference, Duffie, which brings me to something I want to make sure I say on this episode. I added a few things for reference, three books. But the one that I definitely would recommend starting with is The Systems Bible by John Gall. This book is so cool, because it helps you see everything through systems. Everything is a system. A conversation can be a system. An interaction between two people can be a system. I’m not saying this book says that. It’s just like my translation and that you can look – Cooking is a system. There is a process. There is a sequence. It’s really, really cool and it really helps to have things framed in this way and then go out and read the other books on systems. I think it helps a lot. This is definitely what I am starting with and what I would recommend people start with, The Systems Bible. Did you two know this book? [00:36:15] MG: I did not. I don’t. [00:36:17] DC: I’m not aware of it either but I really appreciate the idea. I do think that that's true. If you develop a skill for understanding systems as they are, you’ll basically develop – Frequently, what you’re developing is the ability to recognize patterns, right? [00:36:32] CC: Exactly. [00:36:32] DC: You could recognize those patterns on anything. [00:36:37] MG: Yeah. That's a good segue for just something that came to my mind. Recently, I gave a talk on event-driven architectures. For someone who's not a software developer or architect, it can be really hard to grab all those concepts on asynchrony and eventual consistency and idempotency. There are so many words of like, “What is this all – It sounds weird, way too complex.” But I was reading a book some years ago by Gregor Hohpe. He’s the guy behind Enterprise Integration Patterns. That’s also a book that I have on my list here. He said, “Your barista doesn't use two-phase commit.” So he was basically making this analogy of he was in a coffee shop and he was just looking at the process of how the barista makes the coffee. You pay for it and all the things that can go wrong while your coffee is brewed and served to you. So he was making this relation between the real world and the life and human society to computer systems. There it clicked to me where I was like, “So many problems we solve every day, for example, agreeing on a time where we should meet for dinner or cooking, is a consensus problem, and we solve it.” We even solve it in the case of failure. I might not be able to call Duffie, because he is not available right now. So somehow, we figure out. I always thought that those problems just exist in computer science and distributed systems. But I realized actually that's just a subset of the real world as is. Looking at those problems through the lens of your daily life and you get up and all the stuff, there are so many things that are related to computer systems. [00:38:13] CC: Michael, I missed it. Was it an article you read? [00:38:16] MG: Yes. I need to put that in there as well. Yeah. It’s a plug. [00:38:19] CC: Please put that in there. Absolutely. So far from being any kind of expert in distributed systems, but I have noticed. I have caught myself using systems thinking for even complicated conversations. Even in my personal life, I started approaching things in the systems oriented and just the – just a high-level example. When I am working with systems, I can approach from the beginning, the end. It’s like a puzzle, putting the puzzle together, right? Sometimes, it starts from the middle. Sometimes, it starts from the edges. When I‘m having conversations that I need to be very strategic like I have one shot. Let’s say maybe I’m in a school meeting and I have to reach a consensus or have a solution or have a plan of action. I have to ask the right questions. My private self would do things linearly. Historically like, “Let’s go from the beginning and work out through the end.” Now, I don’t do that anymore. Not necessarily. Sometimes, I like, “Let me maybe ask the last question I would ask and see where it leads and just approach things from a different way.” I don’t know if this is making sense. [00:39:31] MG: It does. It does. [00:39:32] CC: But my thinking has changed. The way I see the possibilities is not a linear thing anymore. I see how you can truly switch things. I use this in programming a lot and also writing. Sometimes, when you’re a beginner writer, you start at the top and you go down to the conclusion. Sometimes, I start I the middle and go up, right? So you can start anywhere. It’s beautiful or it just gives you so many more options. Or maybe I’m just crazy. Don’t listen to me. [00:40:03] DC: I don’t think you’re crazy. I was going to say, one of the funny things about Michael’s point and your point both, it’s like in a way that they have kind of referred to Conway's law, the idea that people will build systems in the way that they communicate. So this is actually – It totally brings it back to that same point of thing, right? We by nature will build systems that we can understand, because that is the constraint in which we have to work, right? So it’s very interesting. [00:40:29] CC: Yeah. But it’s an interesting thing, because we are [inaudible 00:40:32] by the way we are forced to work. For example, I work with constraints and what I'm saying is that that has been influencing my way of thinking. So, yes, I built systems in the way I think but also because of the constraints that I’m dealing with that I have to be – the tradeoffs I need to make, that also turns around and influences the way I think, the way I see the world and the rest of the systems and all the rest of the world. Of course, as I change my thinking, possibly you can theorize that you go back and apply that. Apply things that you learn outside of your work back to your work. It’s a beautiful back-and-forth I think. [00:41:17] MG: I had the same experience with some – When I had to design kind of my first API and think of, “Okay. What would the consumer contract be and what would a consumer expect me to deliver in response and so on?” I was forcing myself and being explicit in communicating and not throwing everything at the client back to confusing but being very explicit and precise. Also on communication every day when you talk to people, being explicit and precise really helps to avoid a lot of problems and trouble. Be it partnership or amongst friends or at work. This is what I took from computer science actually back into my real world in order to taking all those perceptions, perceiving things from a different perspective, and being more precise and explicit in how I respond or communicated. [00:42:07] CC: My take on what you just said, Michael, is we design systems thinking how is this going to fail. We know this is going to fail. We’re going to design for that. We’re going to implement for that. In real life, for example, if I need to get an agreement from someone, I try to understand the person's thinking and just go, “I just had this huge thing this week. This is in my mind.” I’m not constantly thinking about this, I’m not crazy like that. Just a little bit crazy. It’s like, “How does this person think? What do they need to know? How far can I push?” Right? We need to make a decision quickly, so the approach is everything, and sometimes you only get one shot, so yeah. I mean, correct me if I’m wrong. That's how I heard or I interpreted what you just said. [00:42:52] MG: Yeah, absolutely. Spot on. Spot on. So I’m not crazy as well. [00:42:55] CC: Basically, I think we ended up turning this episode into a little bit of like, “Here are great references,” and also a huge endorsement for really going deep into distributed systems, because it’s going to be good for your jobs. It’s going to be good for your life. It’s going to be good for your health. We are crazy. [00:43:17] DC: I’m definitely crazy. You guys might be. I’m not. All right. So we started this episode with the idea of coming to learning distributed systems perhaps without a degree or without a formal education in it. We talked about a ride of different ideas on that subject. Like different approaches that each of us took, how each of us see the problem. Is there any important point that either of you want to throw back into the mix here or bring up in relation to that? [00:43:48] MG: Well, what I take from this episode, being my first episode and getting to know your background, Duffie and Carlisia, is that whoever is going to listen to this episode, whatever background you have, even though you might not be in computer systems or industry at all, I think we three all had approved that whatever background you have, if you’re just curious a little bit and maybe a little bit crazy, you can totally get down the rabbit hole in distributed systems and get totally excited about it. There’s no need for having formal education and the degree to enter this world. It might help but it’s kind of not a high bar that I was perceiving it to be 10 years ago, for example. [00:44:28] CC: Yeah. That’s a good point. My takeaway is it always puzzled me how some people are so good and experienced and such experts in distributed systems. I always look at myself. It’s like, “How am I lacking?” It’s like, “What memo did I miss? What class did I miss? What project did I not work on to get the experience?” What I’m seeing is you just need to put yourself in that place. You need to do the work. But the good news is achieving competency in distributed systems is doable. [00:45:02] DC: My takeaway is as we discussed before, I think that there is no one thing that comprises a distributed system. It is a number of things, right, and basically a number of behaviors or patterns that we see that comprise what a distributed system is. So when I hear people say, “I’m not an expert in distributed systems,” I think, “Well, perhaps you are and maybe you don’t know it already.” Maybe there's some particular set of patterns with which you are incredibly familiar. Like you understand DNS better than the other 20 people in the room. That exposes you to a set of patterns that certainly give you the capability of saying that you are an expert in that particular set of patterns. So I think that to both of your points, it’s like you can enter this stage where you want to learn about distributed systems from pretty much any direction. You can learn it from a CIS background. You can come it with no computer experience whatsoever, and it will obviously take a bit more work. But this is really just about developing and understanding around how these things communicate and the patterns with which they accomplish that communication. I think that’s the important part. [00:46:19] CC: All right, everybody. Thank you, Michael Gasch, for being with us now. I hope to – [00:46:25] MG: Thank you. [00:46:25] CC: To see you in more episodes [inaudible 00:46:27]. Thank you, Duffie. [00:46:30] DC: My pleasure. [00:46:31] CC: Again, I’m Carlisia Campos. With us was Duffie Cooley and Michael Gesh. This was episode 12, and I hope to see you next time. Bye.

Each week, experts in the field will discuss and contrast distributed systems concepts, practices, tradeoffs and lessons learned to help you on your cloud native journey. This space moves fast and we shouldn’t reinvent the wheel. If you’re an engineer, operator or technically minded decision maker, this podcast is for you. [EPISODE] [0:00:41.9] CC: Hi, everybody. Welcome back to The Podlets. We have a new name. This is our first episode with a new name. Don’t want to go much into it, other than we had to change from The Kubelets to The Podlets, because the Kubelets conflicts with an existing project and we’ve thought it was just better to change. The show, the concept, the host, everything stays the same. I am super excited today, because we have a special guest, Joe Beda and Bryan Liles, Michael Gasch. Joe, just give us a brief introduction. The other hosts have been on the show before. People should know about them. Everybody should know about you too, but there's always newcomers in the space, so give us a little bit of a background. [0:01:29.4] JB: Yeah, sure. I'm Joe Beda. I was one of the founders of Kubernetes back when I was at Google, along with Craig McLuckie and Brendan Burns, with a bunch of other folks joining on soon after. I'm currently Principal Engineer at VMware, helping to cover all things Kubernetes and Tanzu related across the company. I came into VMware via the acquisition of Heptio, where Bryan's wearing the shirt today. Left Google, did that with Craig for about two years. Then it's almost a full year here at VMware. We're at 11 months officially as of two days ago. Yeah, really excited to be here. [0:02:12.0] CC: Yeah, I am so excited. Your name is Joe Beda. I always say Joe Beda. [0:02:16.8] JB: You know what? It's four letters and it's easy – it's amazing how many different ways there are to pronounce it. I don't get picky about it. [0:02:23.4] CC: Okay, cool. Well, today I learned. I am very excited about this show, because basically, I get to ask you anything I want. [0:02:35.9] JB: I’ll do my best to answer. [0:02:37.9] CC: Yeah. You can always not answer. There are so many interviews of you out there on YouTube, podcasts. We are going to try to do something different. Let me fire the first question I have for you. When people interview you, they ask you yeah, the usual questions, the questions that are very useful for the community. I want to ask you is this, what are people asking you that you think are the wrong questions? [0:03:08.5] JB: I don't think there's any bad questions like this. I think that there's a ton of interest that's when we're talking about technical stuff at different parts of the Kubernetes stack, I think that there's a lot of business context around the container ecosystem and the companies and around to forming Heptio, all that. A lot of times, I'll have discussions around career and what led me to where I'm at now. I think those are all a lot of really interesting things to talk about all around all that. The one thing that I think is doesn't always come across is these things are all interrelated. At a certain point, the technology and the business and career and work-life – all those things really impact each other. I think it's a mistake to try and take these things in isolation. There's a ton of lead over. I think one of the things that we tried to do at Heptio, and I think we did a good job is recognized that for anybody senior enough inside of any organization, they really have to be able to play all roles, right? At a certain point, everybody is as a business person, fundamentally, in terms of actually moving the ball forward for the company, for the business as a whole. Yeah. I think one of the things that I enjoy is actually to be able to look at things from all those various different angles and try and find a good path forward. [0:04:28.7] BL: All right. Taking that, so you've gone from big co to big co, to VC to small co to big co. What does that unique experience taught you and what can you share with us? [0:04:45.5] JB: Bryan, you know my resume better than I do apparently. I started my career at Microsoft and cut my teeth working on Internet Explorer and doing client side stuff there. I then went to Google in the office up here in Seattle. It was actually in Kirkland, this little hole-in-the-wall, temporary office, preemie work type of thing. I’m thinking, “Hey, I want to do some server-side stuff.” Worked on Google Talk, worked on ads, worked on cloud, started Kubernetes, was a little burned out. Took some time off, goofed off. Did this entrepreneur-in-residence thing for VC and then started Heptio and then sold the VMware. [0:05:23.7] BL: When you're in a big company, especially when you're more junior, it's easy to get caught up in playing the game inside of that company. When I say the game, what I mean is that there are measures of success within big companies and there are ways to advance see approval, see rewards that are all very specific to that company. I think the culture of a company is really defined by what are the parameters and what are the successes, the success factors for getting ahead inside of each of those different companies. I think a lot of times, especially when as a Microsoft straight out at college, I did a couple internships at Microsoft and then joining – leaving Microsoft that first time was actually really, really difficult because there is this fear of like, “Oh, my God. Everything's going to be super different.” It turns out that as you bounced around the industry a little bit, there's actually probably more alike than there is different. The biggest difference I think between large company and small company is really, and I'll throw out some science analogies here. I think, oftentimes organizations are a little bit like the ideal gas law. Okay, maybe going past y'all, but this is – PV = nRT. Pressure times volume equals number of molecules times temperature and the R is a constant. The idea here is that this is an equation where as you add more molecules to a constrained space, that will actually change the temperature and the pressure and these things all rise. What happens is inside of a large company, you end up with so many people within a constrained space in terms of the product space. When you add more people to the organization, or when you're looking to get ahead, it feels very zero-sum. It very much feels like, “Hey, for me to advance, somebody else has to lose.” That's not how the real world works, but oftentimes that's how it feels inside of the big company, is that if it feels zero-sum like that. The liberating thing for being at a startup and I think why so many people get addicted to working at startups is that startups are fundamentally not zero-sum. Everybody succeeds and fails together. When a new person shows up, your thought process is naturally like, “Awesome, we got more cylinders in the engine. We’re going to go faster,” which is not always the case inside of a big company. Now, I think as you get senior enough, all of a sudden these things changes, because you're not just operating within the confines of that company. You're actually again, playing a role in the business, you're looking at the ecosystem, you're looking at the community, you're looking at the competitive landscape and that's where you have your eye on the ball and that's what defines success for you, not the internal company metrics, but really the business metrics is what defines success for you. The thing that I'm trying to do, here at VMware now is as we do Tanzu is make sure that we recognize the unbounded possibilities in front of us inside of this world, make sure that we actually focus our energy on serving customers. In doing so, out-compete others in the market. It's not a zero-sum game, it's not something where as we bring more folks on that we feel we're competing with them. That's a little rambling of an answer. I don't know if that links together for you, Bryan. [0:08:41.8] BL: No, no. That was pretty good. [0:08:44.1] JB: Thanks. [0:08:46.6] MG: Joe, that's probably going to be a context switch now. You touched on the time when you went through the burnout phase. Then last week, I think you put out a tweet on there's so much stuff going on, which tweet I'm talking about. Yeah. In the Kubernetes community, you’re a rock star. At VMware, you're already a rock star being on stage at VMware shaking hands with Pat. I mean, there's so many people, so many e-mails, so many slacks, whatever that you get every day, but still I feel you are able to keep the balance, stay grounded and always have a chat, even though sometimes I don't want to approach you, but sometimes I do when I have some crazy questions maybe. Still you’re not pushing people away. How do you manage with mental stress preventing another burnout? What is the secret sauce here? Because I feel I need to work on that. [0:09:37.4] JB: Well, I mean it's hard. The tweet that I put out was last week I was coming back from Barcelona and tired of travel. I'm looking forward to right now, we're recording this just before KubeCon. Then after KubeCon, planning to go to re:Invent in Vegas, which is just a social denial-of-service. It's just overwhelming being with that. I was tired of traveling. I posted something and came across a little stronger than I wanted to. That I just hate people, right? I was at that point where it's just you're traveling and you just don't want to deal with anybody and every little thing is really bugging you and annoying you. I think burnout is an interesting thing. For me and I think there's different causes for different folks. Number one is that it's always fascinating when you start a new job, your calendar is empty, your responsibilities are low. Then as you are successful and you integrate yourself into the organization, all of a sudden you find that you have more work than you have time to do. Then you hit this point where you try and like, “I'm just going to keep doing it. I'm going to power through.” Then you finally hit this point where you're like, “This is just not humanly possible.” Then you go into a triage mode and then you have to decide what's important. I know that there's more to be done than I can do. I have to be very thoughtful about prioritizing what I'm doing. There's a lot of techniques that you can bring to bear there. Being explicit about what your goals are and what your priorities are, writing those things down, whether it's an OKR process, or whether it's just here's the my top three things that I'm focusing on. Making sure that those things are purposefully meaningful to you, right? Understanding the difference between urgent and important, which these are business booky type of things, but it's this idea of there are things that feel they have to get done right now and then there are things that are long-term important. If you're not thoughtful about how you do things, you spend all your time doing the urgent things, but you never get to the stuff that's the actually long-term important. That's a really easy trap to get yourself into. Finding ways to delegate to folks is really, really helpful here, in terms of empowering others, trusting them. It's hard to let go sometimes, but I think being able to set the stage for other people to be successful is really empowering. Then just recognizing it's not all going to get done and that's okay. You can't hold yourself to expect that. Now with respect to burnout, for me, the biggest driver for burnout in my career has been when I felt personal responsibility over something, but I have been had the tools, or the authority, or the ability to impact it.When you feel in your bones ownership over something, but yet you can't actually really own it, that is what causes burnout for me. I think there are studies talking about how the worst job is middle management. I think it's not being the CEO. It's not being new to the organization, being junior. It's actually being stuck in the middle. Because you're given a certain amount of responsibility, but you aren't always given the tools necessary to be able to drive that. Whereas the folks at the top, oftentimes they don't have those constraints, so they actually own stuff and have agency to be able to take care of it. I think when you're starting on more junior in the organization, the scope of ownership that you feel is relatively minor. That being stuck in the middle is the biggest driver for me for burnout. A big part of that is just recognizing that sometimes you have to take a step back and personally divest that feeling of ownership when really it's not yours to own. I'll give you an example, is that I started Google Compute Engine at Google, which is arguably the foundational cloud service for GCP. As it grew, as it became more important to Google, as it got reorged, more or more of the leadership and responsibilities and decision-making, I’m up here in Seattle, move down the mountain view, a lot of that stuff was focused at had been in the cloud market, but then at Google for 10 or 15 years coming in and they're like, “Okay, that's cute. We got it from here,” right? That was a case where it was my thing. I felt a lot of ownership over it. It was clear after a certain amount of time, hey, you know what? I just work here. I'm just doing my job and I do what I do, but really it’s these other folks that are driving the bus. That's a painful transition to actually go from that feeling of ownership to I just work here. That I think is one of the reasons why oftentimes, people leave the companies. I think that was one of the big drivers for why I ended up leaving Google, was that lack of agency to be able to impact things that I cared about quite a bit. [0:13:59.8] CC: I think that's one reason why – well, I think that working in the companies where things are moving fast, because they have a very clear, very worthwhile goal provides you the opportunity to just have so much work that you have to say no to a lot of things like where you were saying, and also take ownership of pieces of that work, because there's more work to go around than people to do it. For example, since Heptio and VM – okay, I’m plugging. This is a big plug for VMware I guess, but it definitely is a place that's moving fast. It's not crazy. It's reasonable, because everybody, pretty much, wherever one of us grown up. There is so much to do and people are glad when you take ownership of things. That really for me is a big source of work satisfaction. [0:14:51.2] JB: Yeah. I think it's that zero-sum versus positive-sum game. I think that when you – there's a lot more room for you to actually feel that ownership, have that agency, have that responsibility when you're in a positive-sum environment, versus a zero-sum environment. [0:15:04.9] BL: All right, so now I want to ask your technical question. [0:15:08.1] JB: All right. [0:15:09.5] BL: Not a really hard one. Just more of how you think about this. Kubernetes is five and almost five and a half years old. One of the key components of Kubernetes is etcd. Now knowing what we know now and 2019 with Kubernetes have you used etcd as its key store? Or would you have gone another direction? [0:15:32.1] JB: I think etcd is a good fit. The truth of the matter is that we didn't give that decision as much thought as we probably should have early on. We saw that it was relatively easy to stand up and get going with. At least on paper, it had the qualities that we were looking for, so we started building with it and then just ran with it. Something like ZooKeeper was also something we could have taken, but the operational overhead at the time of ZooKeeper was very different from etcd. I think we could have gone in the direction of them and this is why [inaudible 0:15:58.5] for a lot of their tools, where they actually build the data store into the tool in a native way. I think that can lead in some ways to a simpler getting started experience, because there's just one thing to boot up, but also it's more monolithic from a backup, maintenance, recovery type of thing. The one thing that I think we probably should have done there in retrospect is to try and create a little bit more of an arm's length relationship in Kubernetes and etcd. In terms of having some cleaner interfaces, some more contractor and stuff, so that we could have actually swapped something else out. There's folks that are doing it, so it's not impossible, but it's definitely not something that's easy to do, or well-supported. I think that that's probably the thing that I wouldn't change in that space. Another thing we might want to change, I think it might have been good to be more explicit about being able to actually shard things out, so that you could have multiple data stores for multiple resources and actually find a way to horizontally scale. Now we do that with events, because we were writing events into etcd and that's just a totally different stream of data, but everything else right now – I think now there's room to do this into the future. I think we've been able to push etcd vertically up until now. There will come a time where we need to find ways to shard that thing up horizontally. [0:17:12.0] CC: Is it possible though to use a different data store than etcd for Kubernetes? [0:17:18.4] JB: The things that I'm aware of here and there may be more and I may not be a 100% up to date, is I do know that the Azure folks created a proxy layer that speaks to the etcd protocol, but that is actually implemented on the backend using CosmoDB. That approach there was to essentially create a translation layer. Then Rancher created this project, which is a little bit if you've – been added a bit of a fork of Kubernetes, where they're I believe using PostgresSQL as the database for Kubernetes. I haven't looked to see exactly how they ended up swapping that in. My guess is that there's some chewing gum and bailing wiring and it's quite a bit of effort for each version upgrade to be able to actually adapt that moving forward. Don't know for sure. I haven't looked deeply. [0:18:06.0] CC: Okay. Now I would love to philosophize a little bit, or maybe a lot about Kubernetes. In the spirit of thinking of different questions to ask, so I had a bunch of questions and then I was thinking, “How could I ask this question in a different way?” Maybe this is not the right “question.” Here is the way I came up with this question. We’re so divided out there. One camp loves Kubernetes, another camp, "So hard, so complicated, it’s so complex. Why even bother with it? I don't understand why people are using this." Basically, there is that sentiment that Kubernetes is complicated. I don't think anybody would refute that. Now is that even the right way to talk about Kubernetes? Is it even not supposed to be complicated? I mean, what kind of a tool is it that we are thinking, it should just work, it should be just be super simple. Is it true that it should be a super simple tool to use? [0:19:09.4] JB: I mean, that's a loaded question [inaudible]. Let me just first say that number one, if people are complaining, I mean, I'm stealing this from Tim [inaudible], who I think this is the way he takes some of these things in stride. If people are complaining, then you're relevant, right? If nobody is complaining, then nobody cares about what you're doing. I think that it's a good thing that folks are taking a critical look at Kubernetes. That means that they're taking a look at it, right? For five years in, Kubernetes is on an upswing. That's not going to necessarily last forever. I think we have work to do to continually earn Kubernetes’s place in the technology stack over time. Now that being said, Kubernetes is a super, super flexible tool. It can do so many things in so many different situations. It's used from everything from in retail stores across the tens of thousands of stores, any type of solutions. People are looking at it for telco, 5G. People are looking at it to even running it inside cars, which scares me, right? Then all the way up to folks like at CERN using it to do data analytics for hiring and physics, right? The technology that I look at that's probably most comparable to that is something like Linux. Linux is actually scalable from everything from a phone, all the way up to an IBM mainframe, but it's not easy, right? I mean, to be able to adapt it across all that things, you have to essentially download the kernel type, make config and then answer 5,000 questions, right, for those who haven't done that. It's not an easy thing to do. I think that a lot of times, people might be looking at Kubernetes at the wrong level to be able to say this should be simple. Nobody looks at the Linux kernel that you get from git cloning, Linux’s fork and compiling it and saying, “Yeah, this is too hard.” Of course it's hard. It's the Linux kernel. You expect that you're going to have a curated experience if you want something easy, right? Whether that be an Android phone or Ubuntu or what have you. I think to some degree, we're still in the early days where people are dealing with it perhaps at to raw level, versus actually dealing with it in a more opinionated way. Now I think the fascinating thing for Kubernetes is that it provides a lot of the extension points and patterns, so that we don't know exactly what those higher-level easier-to-use abstractions are going to look like, but we know, or at least we're pretty confident that we have the right tools and the right environment to be able to experiment our way there. I think we're not there yet, but we're set up for success. That's the first thing. The second thing is that Kubernetes introduces a whole bunch of different concepts and ideas and these things are different and uncomfortable for folks. It's hard to learn new things. It's hard for me to learn new things and it's hard for everybody to learn new things. When you compare Kubernetes to say, getting started with the modern front-end web development stack, with things like Babel and React and how do you deploy this and what are all these different options and it changes on a weekly basis. There's a hell of a lot in common actually between these two ecosystems. They're both really hard, they both introduce all these new concepts and you have to be embedded in it to really get it. Now that being said, if you just wanted take raw JavaScript, or jQuery and have at it, you can do it and you'll see on Hacker News articles every once in a while where people are like, “Hey, I've programmed my site with jQuery and it's just fine. I don't need all this new stuff,” right? Just like you'll see folks saying like, “I just SSH’d in and actually ran some stuff and it works fine. I don't need all this Kubernetes stuff.” If that works for you, that's great. Kubernetes doesn't have to solve every problem for every person. Then the next thing is that I think that there's a lot of people who've been solving these problems again and again and again and again, but they've been solving them in their own way. It's not uncommon when you look at back-end systems, to join a company, look at what they've built and found that it's a complicated, bespoke system of chewing gum and baling wire with maybe a little bit Ansible, maybe a little bit of Puppets and bash. Everybody has built their own, complex, overwrought system to do a lot of the stuff that Kubernetes does. I think one of the values that we see here is that these things are complex, unique complex to do it, but shared complexity is more valuable than personal complexity. If we can agree on some of these concepts, then that's something that can be leveraged widely and it will fade to the background over time, versus having everybody invent their own complex system every time they need to solve these problems. With that all said, we got a ton of work to do. It's not like we're done here and I'm not going to actually sit here and say Kubernetes is easy, or that every complex thing is absolutely necessary and that we can't find ways to simplify it. We clearly can. I just think that when folks say, “Hey, I just want this to be easy." I think they're being a little bit too naïve, because it's a very difficult problem domain. [0:23:51.9] BL: I'd like to add on to that. I think about this a lot as well. Something that Joe said to me few years back, where Kubernetes is the platform for creating platforms, it is very applicable here. Where we are looking at as an industry, we need to stop looking at Kubernetes as some estimation. Your destination is really running your applications that give you pleasure, or make your business money. Kubernetes is a tool to enable us to think about our applications more, rather than the underlying ecosystem. We don't think about servers. We want to think about storage and networking, even things like finding things in your cluster. You don't think about that. Kubernetes gives it to you. If we start thinking about Kubernetes as a way to enable us to do better things, we can go back to what Joe said about Linux. Back whenever I started using Linux in the mid-90s, guess what? We compiled it. Make them big. That stuff was hard and it was slow. Now think about this, in my office I have three different Linux distributions running. You know what? I don't even think about it anymore. I don't think about configuring X. I don't think about anything. One thing that from Kubernetes is going to grow is it's going to – we're going to figure out these problems and it's going to allow us to think of these other crazy things, which is going to push the industry further. Think maybe 20 years from now if we're still running Kubernetes, who cares? It's just going to be there. We're going to think about some other problem and it could be amazing. This is good times. [0:25:18.2] JB: At one point. Sorry, the dog’s going to bark here. I mean, at one point people cared about some of the BIOS that they were running on our computers, right? That was something that you stressed out about. I mean, back in the bad old days when I was doing DOS gaming and you're like, “Oh, well this BIOS is incompatible with the –” IRQ's and all that. It's just background now. [0:25:36.7] CC: Yeah, I think about this too as a developer. I might have mentioned this before in this podcast. I have never gone from one job to another job and had to use the same deployment system. Every single job I've ever had, the deployment system is completely different, completely different set of tooling and completely different process. Just being able to walk out from one job to another job and be able to use the same platform for deployment, it must be amazing. On the flip side, being able to hire people that will join your organization already know how your deployment works, that has value in itself. It's a huge value that I don't think people talk about enough. [0:26:25.5] JB: Well honestly, this was one of the motivations for creating Kubernetes, is that I looked around Google early on and Google is really good at importing open source, circa 2000, right? This is like, “Hey, you want to use libpng, or you want to use this library, or whatever.” That was the type of open source that Google is really, really good at using. Then Google did things, like say release the Big Table paper. Then somebody went through and then created Cassandra out of it. Maybe there's some ideas in Cassandra that actually build on top of big table, or you're looking at MapReduce versus Hadoop. All of a sudden, you found that these things diverge and Google had zero ability to actually import open source, circa 2010, right? It could not back import systems, because the operational characteristics of these things were solely alien when compared to something like Borg. You see this also, like we would acquire companies and it would take those companies way too long to be able to essentially re-platform themselves on top of Borg, because it was just so different. This is one of the reasons, honestly, why we ended up doing something like GCE is to actually have a platform that was actually more familiar from acquisition. It's one of the reasons we did it. Then also introducing Kubernetes, it's not Borg. It's a cousin of Borg inside of Google. For those who don't know, Borg is the container system that’s been in production at Google for probably 15 years now, and the spiritual grandfather to Kubernetes in a lot of ways. A lot of the ideas that you learn from Kubernetes are applicable to Borg. It's not nearly as big a leap for people to actually change between them, as it was before, Kubernetes was out there. [0:27:58.6] MG: Joe, I got a similar question, because it seems to be like you're a platform builder. You've worked on GCE, Kubernetes obviously. If you would be talking to another platform architect or builder, what would be something that you would recommend to them based on your experiences? What is a key ingredient, technically speaking of a platform that you should be building today, or the main thing, or the lesson learned that you had from building those platforms, like technical advice, if you will? [0:28:26.8] JB: I mean, that's a really good question. I think in my mind, the mark of a good platform is when people can use it to do things that you hadn't imagined when you were building it, right? The goal here is that you want a platform to be a force multiplier. You wanted to enable people to do amazing things. You compare, again the Linux kernel, even something as simple as our electrical grid, right? The folks who established those standards, God knows how long ago, right? A 150 years ago or whenever, the whole Tesla versus Thomas Edison, [inaudible]. Nobody had any idea the long-term impact that would have on society over time. I think that's the definition of a successful platform in my mind. You got to keep that in mind, right? I think that for me, a lot of times people design for the first five minutes at the expense of the next five years. I've seen in a lot of times where you design for hey, I'm getting a presentation. I want to be able to fit something amazing on one slot. You do it, but then all of a sudden somebody wants to do something different. They want to go off course, they want to go off the rails, they want to actually experiment and the thing is just brittle. It's like, “Hey, it does this. It doesn't do anything else. Do you want to do something else? Sorry, this isn't the tool for you.” For me, I think that's a trap, right? Because it's easy to get it early users based on that very curated experience. It's hard to keep those users as they actually start using the thing in anger, as they start interfacing with the real world, as they deal with things that you didn't think of as a platform. I'm always thinking about how can every that you put in the platform be used in multiple ways? How can you actually make these things be composable building blocks, because then that gives you the opportunity for folks to actually compose them in ways that you didn't imagine, starting out. I think that's some of it. I started my career at Microsoft working on Internet Explorer. The fascinating thing about Microsoft is that through and through and through and through Microsoft is a platform company. It started with DOS and Windows and Office, but even though Office is viewed as a platform inside of Microsoft. They fundamentally understand in their bones the benefit of actually starting that platform flywheel. It was really interesting to actually be doing this for the first browser wars of IE versus Netscape when I started my own career, to actually see the fact that Microsoft always saw Internet Explorer as a platform, whereas I think Netscape didn't really get it in the same way, right? They didn't understand the potential, I think in the way that Microsoft did it. For me, I mean, just being where you start your career, oftentimes you actually sets your patterns in terms of how you look at things over time. I think a lot of this platform thinking comes from just imprinting when I was a baby developer, I think. I don't know. It takes a lot of time to really internalize that stuff. [0:31:14.1] BL: The lesson here is this a good one, is that when we're building things that are way bigger than us, don't think of your product as the end goal. Think of it as an enabler. When it's an enabler, that's where you get that X multiplier. Then that's where you get all the residuals. Microsoft actually is a great example of it. My gosh. Just think of what Microsoft has been able to do with the power of Office? [0:31:39.1] JB: Yeah. I look at something like VB in the Microsoft world. We still don't have VB for the cloud era. We still haven't created that. I think there's still opportunity there to actually strike. VB back in the day, for those who weren't there, struck this amazing balance of being easy to get started with, but also something that could actually grow with you over time, because it had all these extension mechanisms where you could actually – there's the marketplace controls that you could buy, you could partner with other developers that were writing C or C++. It was an incredible platform. Then they leverage to Office to extend the capabilities of VB. It's an amazing ecosystem. Sorry. I didn't mean to interrupt you, Bryan. [0:32:16.0] BL: Oh, no. That's all good. I get as excited about it as you do whenever I think about it. It's a pretty exciting place to be. [0:32:21.8] JB: Yeah. I'll talk to VC's, because I did a startup and the EIR thing and I'll have them ask me things like, “Hey, where should we invest in the Kubernetes space?” My answer is using the BS analogy like, “You got to go where the puck is going.” Invest in the things that Kubernetes enables. What are the things that people can do now that they couldn't do pre-Kubernetes? Those are the things where we're going to see the explosion of growth. It's not about the Kubernetes. It's really about a larger ecosystem that Kubernetes is the seed crystal for. [0:32:56.2] BL: For those of you listening, if you want to get anything out of here, rewind back about 20 seconds and play that over and over again, what Joe just said. [0:33:04.2] MG: Yeah. This was brilliant. [0:33:05.9] BL: It’s where the puck is going. It's not where we are now. We're building for the future. We're not building for now. [0:33:11.1] MG: I'm looking at this tweetable quotes here, the last 20 seconds, so many tweetable quotes. We have to decide which ones to tweet then. [0:33:18.5] CC: Well, we’ll tweet them all. [0:33:20.0] MG: Oh, yes. [0:33:21.3] JB: Here’s another thing. Here’s another piece of career advice. Successful people are good storytellers. You can have the most beautiful technology, if you can't tell the human story about it, about what it does for folks, then nobody will care. I spend a lot of the time on Twitter and probably too much time, if you ask my family. That medium of being able to actually distill your thoughts down into something that is tweetable, quotable, really potent, that is a skill that's worth developing and it's a skill that's worth valuing. Because there's things that are rolling around in my head and I still haven't found a way to get them into a tweet. At some point, I'll figure it out and it'll be a thing. It takes a lot of time to build that skill to be able to refine like that. [0:34:08.5] CC: I want to say an anecdote of myself. I interview a small – so tiny startup, maybe less than 10 people at the time in Cambridge back when I lived up there. The guy was borderline wanting to hire me and no. I sent him an e-mail to try to influence his decision and it was a long-ass e-mail. They said, “No, thank you.” Then I think we had a good rapport. I said, well, anything you can tell me about your decision then? He said something along the lines like, I was too verbose. That was pre-Twitter. Twitter I think existed, but it was at the very beginning, I wasn't using it. Yeah, people. Be concise. Decision-makers don't have time to read long things. You need to be able to convey your message in short sentences, few sentences. It's crucial. [0:35:07.5] BL: All right, so we're nearing the end. I want to ask another question, because these are random questions for Joe. Joe, it is the week before KubeCon North America 2019 and today is actually an interesting day. A couple of neat things happened today. We had Docker. It was neat. Docker split somewhat and it sold part of it and now they're going to be a tools company. That's neat. We're all still trying decoding what that actually is. Here's the neat piece, Apple released a laptop that can have 64 gigabytes of memory. [0:35:44.4] MG: Has an escape key. [0:35:45.7] BL: It has an escape key. [0:35:47.6] MG: This is brilliant. [0:35:48.6] BL: Yeah. I think the question was what do you think about that? [0:35:52.8] JB: Okay. Well, so first of all, I mean, Docker is fascinating and I think this is – there's a lot of lessons there and I'm not sure I'm the one to tell them. I think it's easy to armchair-quarterback these things. It's hard to live that story. I think that it's fun to play that what-if game. I think it does show that this stuff is hard. You can have everything in your grasp and then just have it all slip away. I think that's not anybody's fault. It's just there's different strategies, different approaches in how this stuff plays out over time. On the laptop thing, I think my current laptop has 16 gigs of RAM. One of the things that we're seeing is that as we move towards a microservices world, I gave a talk about this probably three or four years ago. As we move to a microservices world, I think there's one stage where you create a bunch of microservices, but you still view those things as an app. You say, "This microservice belongs to this app." Within a mature organization, those things start to grow and eventually what you find is that you have services that are actually useful for multiple apps. Your entire production infrastructure becomes this web of services that are calling each other. Apps are just entry points into these things at different points of that web of infrastructure. This is the way that things work at Google. When you see companies that are microservices-based, let's take an Uber, or Lyft or an Airbnb. As they diversify the set of products that they're offering, you know they're not running completely independent stacks. You know that there's places where these things connect to behind the scenes in a microservices world. What does that mean for developers? What it means is that you can no longer fit an entire company's worth of infrastructure on your laptop anymore. Within a certain constraint, you can go through and actually say, “Hey, I can bring up this canonical cut of microservices. I can bring that up on my laptop, but it will have dependencies that I either have to actually call into the prod dependencies, call into specialized staging, or mock those things out, so that I can actually run this thing locally and develop it.” With 64 gig of RAM, I can run more on my laptop, right? There's a little bit of kick in that can down the road in terms of okay, there's this race between more microservicey versus how much I can port on my laptop. The interesting thing is that where is this going to end? Are we going to have the ability to bring more and more with your laptop? Are you going to be able to run in the split brain thing across like there's people who will create network connections between these things? Or are we going to move to a world where you're doing more development on cluster, in the cloud and your laptop gets thinner and thinner, right? Either you absolutely need 64 gig because you're pushing up against the boundaries of what you can do on your laptop, or you've given up and it's all running in the cloud. Yet anyways, you might as well just use a Chromebook. It's fascinating that we're seeing this divergence of scaling up, versus actually moving stuff to the cloud. I can tell you at Google, a lot of folks, even developers can actually be super, super productive with something relatively thin like Chromebook, because there's so many tools there that really are targeted at doing all that stuff remotely, in Google's production data centers and such. That's I think the interesting implication from a developer point of view with 64 gigabytes of RAM. What you going to do Bryan? You're going to get the 64 gig Mac? You’re going to do it? [0:39:11.2] BL: It’s already coming. They'll be here week after next. [0:39:13.2] JB: You already ordered it? You are such an Apple fanboy. Oh, man. [0:39:18.6] BL: Oh, I'm actually so not to go too much into it. I am a fan of lots of memory. You know what? We work in this cloud native world. Any given week, I’ll work on four to five projects. I'm lazy. I don't want to shut any of them down. Now with 64 gigs, I don't have to shut anything down. [0:39:37.2] JB: It was so funny. When I was at Microsoft, everybody actually focused on Microsoft Windows boot time. They’re like, “We got to make it boot faster. We got to make it boot faster.” I'm like, I don't boot that often. I just want the thing to resume from sleep, right? If you can make that reliable on that theme. [0:39:48.7] CC: Yeah. I frequently have to restart my computer, because of memory issues. I don't want to know which app is taking up memory. I have a tool that I can look up, but I just shut it down, flush the memory. I do have a question related to Docker. Kubernetes, I don't know if it's right to say that Kubernetes is so reliant on Docker, because I know it works with other container technologies as well. In the worst case scenario, it's obviously, I have no reason to predict this, but in the worst case scenario where Docker, let's say is discontinued, how would that affect Kubernetes? [0:40:25.3] JB: Early on when we were doing Kubernetes and you're in this relationship with a company like Docker, I looked at what Docker was doing and you're like, “Okay, where is the real value here over time?” In my mind, I thought that the interface with developers that distributed kernel, that API surface area of Kubernetes, that was really the thing and that a lot of the Docker stuff was over time going to fade to the background. I think we've seen that happen, because when we talk about production systems, we definitely have moved past Docker and we have the CRI, we have Container D, which it was essentially built by Docker, donated to the CNCF as it made its way towards graduation. I think it's graduated now. The governance ties to Docker have been severed at this point. In production systems for Kubernetes, we've moved past that. I still think that there's developer experiences oftentimes reliant on Docker and things like Docker files. I think we're moving past that also. I think that if Docker were to disappear off the face of the earth, there would be some adjustment, but I think we have the right toolkits and the right systems to be able to do that. Some of that is open sourced by Docker as part of the Moby project. The whole Docker file evaluation flow is actually in this thing called Build Kit that you can actually use in different contexts outside of the Docker game. I think there's a lot of the building action. The thing that I think is the most influential thing that actually I think will stand the test of time is the Docker container image format. That artifact that you upload, that you download, the registry APIs. Now those things have been codified and are moving forward slowly under the OCI, the open container initiative project, which is a little bit of a sister foundation niche type of thing to the CNCF. I think that's the influence over time. Then related to that, I think the world should be a little bit worried about Docker Hub and what that means for Docker Hub over time, because that is not a cheap service to run. It's done as a public good, similar to github. If the commercial aspects of that are not healthy, then I think it might be disruptive if we see something bad happen with Docker Hub itself. I don't know what exactly the replacement for that would be overnight. That'd be incredibly disruptive. [0:42:35.8] CC: Should be Harbour. [0:42:37.7] JB: I mean, Harbour is a thing, but somebody's got a run it and somebody's got to pay the bandwidth bills, right? Thank you to Docker for paying those bandwidth bills, because it's actually been good for not just Docker, but for our entire ecosystem to be able to do that. I don't know what that looks like moving forward. I think it's going to be – I mean, maybe github with github artifacts and it's going to pick up the slack. We’re going to have to see. [0:42:58.6] MG: Good. I have one last question from my end. Totally different topic, not Docker at all. Or maybe, depends on your answer to it. The question is you're very technical person, what is the technology, or the stuff that your brain is currently spinning on, if you can disclose? Obviously, no secrets. What keeps you awake at night, in your brain? [0:43:20.1] JB: I mean, I think the thing that – a couple of things, is that stuff that's just completely different from our world, I think is interesting. I think we've entered at a place where programming computers, and so stuff is so specialized. That again, I talk about if you made me be a front-end developer, I would flail for several months trying to figure out how to even be productive, right? I think similar when we look at something like machine learning, there's a lot of stuff happening there really fast. I understand the broad strokes, but I can't say that I understand it to any deep degree. I think it's fascinating and exciting the amount of diversity in this world and stuff to learn. Bryan's asked me in the past. It's like, “Hey, if you're going to quit and start a new career and do something different, what would it be?” I think I would probably do something like generative art, right? Essentially, there's folks out there writing these programs to generate art, a little bit of the moral descendant of Demoscene that was I don't know. I wonder was the Demoscene happened, Bryan. When was that? [0:44:19.4] BL: Oh, mid 90s, or early 90s. [0:44:22.4] JB: That’s right. I was never super into that. I don't think I was smart enough. It's crazy stuff. [0:44:27.6] MG: I actually used to write demoscenes. [0:44:28.8] JB: I know you did. I know you did. Okay, so just for those not familiar, the Demoscene was essentially you wrote essentially X86 assembly code to do something cool on screen. It was all generated so that the amount of code was vanishingly small. It was this puzzle/art/technical tour de force type of thing. [0:44:50.8] BL: We wrote trigonometry in a similar – that's literally what we did. [0:44:56.2] JB: I think a lot of that stuff ends up being fun. Stuff that's related to our world, I think about how do we move up the stack and I think a lot of folks are focused on the developer experience, how do we make that easier. I think one of the things through the lens of VMware and Tanzu is looking at how does this stuff start to interface with organizational mechanics? How does the typical enterprise work? How do we actually make sure that we can start delivering a toolset that works with that organization, versus working against the organization? That I think is an interesting area, where it's hard because it involves people. Back-end people like programmers, they love it because they don't have to deal with those pesky people, right? They get to define their interfaces and their interfaces are pure and logical. I think that UI work, UX work, anytime when you deal with people, that's the hardest thing, because you don't get to actually tell them how to think. They tell you how to think and you have to adapt to it, which is actually different from a lot of back-end here in logical type of folks. I think there's an aspect of that that is user experience at the consumer level. There's developer experience and there's a whole class of things, which is maybe organizational experience. How do you interface with the organization, versus just interfacing, whether it's individuals in the developer, or the end-user point of view? I don't know if as an industry, we actually have our heads wrapped around that organizational limits. [0:46:16.6] CC: Well, we have arrived at the end. Makes me so sad, because we could talk for easily two more hours. [0:46:24.8] JB: Yeah, we could definitely keep going. [0:46:26.4] CC: We’re going to bring you back, Joe. Don’t worry. [0:46:28.6] JB: For sure. Anytime. [0:46:29.9] CC: Or do worry. All right, so we are going to release these episodes right after KubeCon. Glad everybody could be here today. Thank you.
