When we think of injury prevention for runners, cyclists and triathletes we tend to focus on non-nutrition factors - training loads, shoes, biomechanics, stretching, foam rolling, strength and conditioning, and so on. But what about nutrition - does it have a role to play too? We're joined by sports dietitian and ultra-runner Erin Colebatch, whose current research seeks to answer this question.   Podcast Guest: Erin Colebatch - University of South Australia & Ultra Appetites    Erin's online presence: X/Twitter: @ErinColebatch Instagram: @ultraappetites Website: ultraappetites.com.au   Erin's research mentioned: Colebatch, EA et al.

David Colebatch, CEO of Tidal, joins Corey on Screaming in the Cloud to discuss Tidal's recent shift to a product-led approach and why empathizing with customers is always their most important job. David describes what it was like to grow the company from scratch on a boot-strapped basis, and how customer feedback and challenges inform the company strategy. Corey and David discuss the cost-savings measures cloud customers are now embarking on, and David discusses how constant migrations are the new normal. Corey and David also discuss the impact that generative AI is having not just on tech, but also on creative content and interactions in our everyday lives. About David David is the CEO & Founder of Tidal.  Tidal is empowering businesses to transform from traditional on-premises IT-run organizations to lean-agile-cloud powered machines.Links Referenced: Company website: https://tidal.cloud LinkedIn: https://www.linkedin.com/in/david-colebatch/ TranscriptAnnouncer: Hello, and welcome to Screaming in the Cloud with your host, Chief Cloud Economist at The Duckbill Group, Corey Quinn. This weekly show features conversations with people doing interesting work in the world of cloud, thoughtful commentary on the state of the technical world, and ridiculous titles for which Corey refuses to apologize. This is Screaming in the Cloud.Corey: Welcome to Screaming in the Cloud. I'm Corey Quinn. Returning guest today, David Colebatch is still the CEO at Tidal. David, how have you been? It's been a hot second.David: Thanks, Corey. Yeah, it's been a fantastic summer for me up here in Toronto.Corey: Yeah, last time I saw you, was it New York or was it DC? They all start to run together to me.David: I think it was DC. Yeah.Corey: That's right. Public Sector Summit where everything was just a little bit stranger than most of my conversations. It's, “Wait, you're telling me there's a whole bunch of people who use the cloud but don't really care about money? What—how does that work?” And I say that not from the position of harsh capitalism, but from the position of we're a government; saving costs is nowhere in our mandate. Or it is, but it's way above my pay grade and I run the cloud and call it good. It seems like that attitude is evolving, but slowly, which is kind of what you want to see. Titanic shifts in governing are usually not something you want to see done on a whim, overnight.David: No, absolutely. A lot of the excitement at the DC summit was around new capabilities. And I was actually really intrigued. It was my first time in the DC summit, and it was packed, from the very early stages of the morning, great attendance throughout the day. And I was just really impressed by some of the new capabilities that customers are leveraging now and the new use cases that they're bringing to market. So, that was a good time for me.Corey: Yeah. So originally, you folks were focused primarily on migrations and it seems like that's evolving a little bit. You have a product now for starters, and the company's name is simply Tidal, without a second word. So, brevity is very much the soul of wit, it would seem. What are you doing these days?David: Absolutely. Yeah, you can find us at tidal.cloud. Yeah, we're focused on migrations as a primary means to help a customer achieve new capabilities. We're about accelerating their journey to cloud and optimizing once they're in cloud as well. Yeah, we're focused on identifying the different personas in an enterprise that are trying to take that cloud journey on with people like project, program managers, developers, as well as network people, now.Corey: It seems, on some level, like you are falling victim to the classic trap that basically all of us do, where you have a services company—which is how I thought of you folks originally—now, on some level, trying to become a product or a platform company. And then you have on the other side of it—places that we're—“Oh, we're a SaaS company. This is hard. We're going to do services instead.” And it seems like no one's happy. We're all cats, perpetually on the wrong side of a given door. Is that an accurate assessment for where you are? Or am I misreading the tea leaves on this one?David: A little misread, but close—Corey: Excellent.David: You're right. We bootstrapped our product company with services. And from day one, we supported our customers, as well as channel partners, many of the [larger size 00:03:20] that you know, we supported them in helping their customers be successful. And that was necessary for us as we bootstrapped the company from zero. But lately, and certainly in the last 12 months, it's very much a product-led company. So, leading with what customers are using our software for first, and then supporting that with our customer success team.Corey: So, it's been an interesting year. We've seen simultaneously a market correction, which I think has been sorely needed for a while, but that's almost been overshadowed in a lot of conversations I've had by the meteoric rise and hype around generative AI. Have you folks started rebranding everything with a fresh coat of paint labeled generative AI yet as it seems like so many folks have? What's your take on it?David: We haven't. You won't see a tidal.ai from us. Look, our thoughts are leveraging the technology as we always had to provide better recommendations and suggestions to our users, so we'll continue to embrace generative AI as it applies to specific use cases within our product. We're not going to launch a brand new product just around the AI theme.Corey: Yeah, but even that seems preferable to what a lot of folks are doing, which is suddenly pivoting their entire market positioning and then act, “Oh, we've been working in generative AI for 5, 10, 15 years,” in some cases. Google and Amazon most notably have talked about how they've been doing this for decades. It's, “Cool. Then why did OpenAI beat you all to the punch on this?” And in many cases, also, “You've been working on this for decades? Huh. Then why is Alexa so terrible?” And they don't really have a good talking point for that yet, but it's the truth.David: Absolutely. Yeah. I will say that the world changed with the OpenAI launch, of course, and we had a new way to interact with this technology now that just sparked so much interest from everyday people, not just developers. And so, that got our juices flowing and creativity mode as well. And so, we started thinking about, well, how can we recommend more to other users of our system as opposed to just cloud architects?You know, how can we support project managers that are, you know, trying to summarize where they're at, by leveraging some of this technology? And I'm not going to say we have all the answers for this baked yet, but it's certainly very exciting to start thinking outside the box with a whole new bunch of capabilities that are available to us.Corey: I tried doing some architecture work with Chat-Gippity—yes, that is how I pronounce it—and it has led me down the primrose path a little bit because what it says is often right. Mostly. But there are some edge-case exceptions of, “Ohh, it doesn't quite work that way.” It reminds me at some level of a junior engineer who doesn't know the answer, so they bluff. And that's great, but it's also a disaster.Because if I can't trust the things you tell me and you to call it out when you aren't sure on something, then I've got to second guess everything you tell me. And it feels like when it comes to architecture and migrations in particular, the devil really is in the details. It doesn't take much to design a greenfield architecture on a whiteboard, whereas being able to migrate something from one place to another and not have to go down in the process? That's a lot of work.David: Absolutely. I have used AI successfully to do a lot of research very quickly across broad market terms and things like that, but I do also agree with you that we have to be careful using it as the carte blanche force multiplier for teams, especially in migration scenarios. Like, if you were to throw Chat-Gippity—as you say—a bunch of COBOL code and say, “Hey, translate this,” it can do a pretty good job, but the devil is in that detail and you need to have an experienced person actually vet that code to make sure it's suitable. Otherwise, you'll find yourself creating buggy things downstream. I've run into this myself, you know, “Produce some Terraform for me.” And when I generated some Terraform for an architecture I was working on, I thought, “This is pretty good.” But then I realized, it's actually two years old and that's about how old my skills were as well. So, I needed to engage someone else on my team to help me get that job done.Corey: So, migrations have been one of those things that people have been talking about for well, as long as we've had more than one data center on the planet. “How do we get our stuff from over here to over there?” And so, on and so forth. But the context and tenor of those conversations has changed dramatically. What have you seen this past year or so as far as emerging trends? What is the industry doing that might not be obvious from the outside?David: Well, cost optimization has been number one on people's minds, and migrating with financial responsibility in mind has been refreshing. So, working backwards from what their customer outcomes are is still number one in our book, and when we see increasingly customers say, “Hey, I want to migrate to cloud to close a data center or avoid some capital outlay,” that's the first thing we hear, but then we work backwards from what was their three-year plan. And then what we've seen so far is that customers have changed from a very IT-centric view of cloud and what they're trying to deliver to much more business-centric. Now, they'll say things like, “I want to be able to bring new capabilities to market more quickly. I want to be able to operate and leverage some of these new generative AI technologies.” So, they actually have that as a driving force for migrations, as opposed to an afterthought.Corey: What I have found is that, for whatever reason, not giving a shit about the AWS bill in my business was a zero-interest-rate phenomenon. Suddenly people care an awful lot. But they're caring is bounded. If there's a bunch of easy stuff to do that saves a giant pile of money, great, yeah, most folks are going to do that. But then it gets into the idea of opportunity cost and trade-offs. And there's been a shift there that I've seen where people are willing to invest more in that cost-cutting work than they were in previous years.It makes sense, but it's also nice to finally have a moment to validate what I've assumed for seven years now that, yeah, in a recession or a retraction of the broader industry, suddenly, this is going to be top-of-mind for a lot of folks. And it's nice to see that that approach was vindicated because the earlier approach that I saw when we saw something like this was at the start of Covid. And at that point, no one knew what was happening week-to-week and consulting leads basically stopped for six months. And that was oh, maybe we don't have a counter-cyclical business. But no, it turns out that when money means something again as interest rates rise, people care about it more.David: Yeah. It is nice to see that. And people are trying to do more with less and become more efficient in an advanced pace these days. I don't know about you, but I've seen the trends towards the low-hanging fruit being done at this point so people have already started using savings plans and capabilities like that, and now they're embarking in more re-architecture of applications. But I think one stumbling block that we've noticed is that customers are still struggling to know where to apply those transformations across their portfolio. They'll have one or two target apps that everybody knows because they're the big ones on the bill, but beneath that, the other 900 applications in their portfolio, which ones do I do next? And that's still a question that we're seeing come up, time and again.Corey: One thing that I'm starting to see people talking about from my perspective, has been suddenly they really care about networking in a way that they did not previously. And I mean, this in the TCP/IP sense, not the talking to interesting people and doing interesting things. That's been basically steady-state for a while. But from my perspective, the conversations I'm having are being driven by, “Wait a minute. AWS is going to start charging $3.50 a month per assigned IPV4 address. Oh, dear. We have been careless in our approach to this.” Is that something that you're seeing shaping the conversations you're having with folks?David: Oh yeah, absolutely. I mean right off the bat, our team went through very quickly and inventoried our IPV4, and certainly, customers are doing that as well. I found that, you know, in the last seven years, the migration conversations were having become broader across an enterprise customer. So, we've mapped out different personas now, and the networking teams playing a bigger role for migrations, but also optimizations in the cloud. And I'll give you an example.So, one large enterprise, their networking team approached us at the same time as their cloud architects who were trying to work on a migration approached us. And the networking team had a different use case. They wanted to inventory all the IP addresses on-premises, and some that they already had in the cloud. So, they actually leveraged—shameless plug here—but they leveraged out a LightMesh IPAM solution to do that. And what that brought to light for us was that the integration of these different teams working together now, as opposed to working around each other. And I do think that's a bit of a trend change for us.Corey: IPAM has always been one of those interesting things to me because originally, the gold standard in this space was—let's not kid ourselves—a Microsoft Excel spreadsheet. And then there are a bunch of other offerings that entered into the space. And for a while I thought most of these were ridiculous because the upgrade was, you know, Google Sheets so you can collaborate. But having this done in a way with particular permissions and mapping in a way that's intuitive and doesn't require everyone to not mess up when they're looking at it, especially as you get into areas of shared responsibility between different divisions or different team members who are in different time zones and whatnot, this becomes a more and more intractable problem. It's one of those areas where small, scrappy startups don't understand what the fuss is about, and big enterprises absolutely despair of finding something that works for them.AWS launched their VPC IPAM offering a while back and if you look at it from the perspective of competing with Google Sheets, its pricing is Looney Tunes. But I've met an awful lot of people who have sworn by it in the process, as they look at these things. Now, of course, the caveat is that like most AWS offerings, it's great in a pure AWS native environment, but as soon as you start getting into other providers and whatnot, it gets very tricky very quickly.David: No, absolutely. And usability of an IP address management solution is something to consider. So, you know, if you're trying to get on board with IPAM, do you want to do three easy steps or do you want to follow 150? And I think that's a really big barrier to entry for a lot of networking teams, especially those that are not too familiar with cloud already. But yeah, where we've seen the networking folks get more involved is around, like, identifying endpoints and devices that must be migrated to cloud, but also managing those subnets and planning their VPC designs upfront.You've probably seen this before yourself where customers have allocated a whole bunch of address space over time—an overlapping address space, I should say—only to then later want to [peer 00:13:47] those networks. And that's something that if you think you're going to be doing downstream, you should really plan for that ahead of time and make sure your address space is allocated correctly. Problems vary. Like, everyone's architecture is different, of course, but we've certainly noticed that being one of the top-button items. And then that leads into a migration itself. You're not migrating to cloud now; you're migrating within the cloud and trying to reorganize address spaces, which is a whole other planning activity to consider.Corey: When you take a look at, I guess the next step in these things, what's coming next in the world of migrations? I recently got to talk to someone who was helping their state migrate from, effectively, mainframes in many cases into a cloud environment. And it seems, on some level, like everyone on a mainframe, one, is very dependent on that workload; those things are important, so that's why they're worth the extortionate piles of money, but it also feels like they've been trying to leave the mainframe for decades in many cases. Now, there's a sense that for a lot of these folks, the end is nigh for their mainframe's lifespan, so they're definitely finally taking the steps to migrate. What's the next big frontier once the, I guess, either the last holdouts from that side of the world wind up getting into a cloud or decide they never will? It always felt to me like migrations are one of those things that's going to taper off and it's not going to be something that is going to be a growth industry because the number of legacy workloads is, at least theoretically, declining. Not so sure that's accurate, though.David: I don't think it is either. If we look back at past migrations, you know, 90, 95% of them are often lift-and-shift to EC2 or x86 on VMware in the cloud. And a lot of the work that we're seeing now is being described as optimization. Like, “Look at my EC2 workloads and come up with cloud-native or transformative processes for me.” But those are migrations as well because we run the same set of software, the same processes over those workloads to determine how we can re-platform and refactor them into more native services.So, I think, you know, the big shift for us is just recognizing that the term ‘migrations' needs to be well-defined and communicated with folks. Migrations are actually constant now and I would argue we're doing more migrations within customers now than we have in the past because the rate of change is just so much faster. And I should add, on the topic of mainframe and legacy systems, we have seen this pivot away from teams looking for emulation layers for those technologies, you know, where they want to forklift the functionality, but they don't want to really roll up their sleeves and do any coding work. So, they're previously looking to automatically translate code or emulate that compute layer in the cloud, and the big pivot we've seen in the last 12 months, I'd say, is that customers are more willing to actually understand how to rebuild their applications in the cloud. And that's a fantastic story because it means they're not kicking that technology debt can down the road any further. They're really trying to embrace cloud and leverage some of these new capabilities that have come to market.Corey: What do you see as, I guess, the reason that a number of holdouts have not yet done a migration? Like, historically, I've seen some that are pretty obvious: the technology wasn't there. Well, cloud has gotten to a point now where it is hard to identify a capability that isn't there in some form. And there's always been the sunk cost fallacy where, “Well, we've already bought all this stuff, and it's running here, so if we're not replacing it anytime soon, there's no cost benefit for us to replace it.” And that's actually correct. That's not a fallacy there. But there's also the, “Well, it would be too much work to move.” Sometimes true, sometimes not. Are you seeing a shift in the reasons that people are giving to not migrate?David: No, I haven't. It's been those points mostly. And I'd say one of the biggest inhibitors to people actually getting it done is this misconception that it costs a lot of money to transform and to adopt cloud tools. You've seen this through the technology keeps getting easier and easier to adopt and cheaper to use. When you can provision services for $0 a month and then scale with usage patterns, there's really no reason not to try today because the opportunity cost is so low.So, I think that one of the big inhibitors that comes up, though, is this cultural barrier within organizations where teams haven't been empowered to try new things. And that's the one thing that I think is improving nowadays, as more of this how-to-build-in-the-cloud capability becomes permeated throughout the organization. People are saying, “Well, why can't we do that?” As opposed to, “We can't do that.” You know what I mean? It's a subtle difference, but once leadership starts to say, “Why can't we do this modern thing in the cloud? Why can't we leverage AI?” Teams are given more rope to try and experiment, and fail, of course. And I think ultimately, that culture shift is starting to take root across enterprise and across public sector as well.Corey: One of the things that I find surprising is the enthusiasm with which different market segments jump onto different aspects of cloud. Lambda is a classic example, in that it might be one of the services that is more quickly adopted by enterprises than by startups and a lot of cases. But there's also the idea of, “Oh, we built this thing last night, and it's awesome.” And enterprises, like you know, including banks and insurance companies don't want to play those games, for obvious reasons.Generative AI seems to be a mixed bag around a lot of these things. Have you had conversations with a number of your clients around the generative AI stuff? Because I've seen Amazon, for example, talking about it, “Oh, all our customers are asking us about it.” And, mmm, I don't know. Because I definitely have questions about and I'm exploring it, but I don't know that I'm turning to Amazon, of all companies, to answer those questions, either.David: Yeah. We've certainly had customer conversations about it. And it depends, again, on those personas. On the IT side, the conversations are mostly around how can they do their jobs better. They're not thinking forwards about the business capabilities. So, IT comes to us and they want to know how can we use generative AI to create Lambda functions and create stateless applications more quickly as a part of a migration effort. And that's great. That's a really cool use case. We've used that generative AI approach to create code ourselves.But on the business side, they're looking forwards, they want to use generative AI in the, again, the sample size of my customer conversations, but they see that the barrier to entry is getting their data in a place that they can leverage it. And to them, to the business, that's what's driving the migration conversations they're having with us, is, “How do I exfil my data and get it into the cloud where I can start to leverage these great AI tools?”Corey: Yeah, I'm still looking at use cases that I think are a little less terrifying. Like, I want to wind up working on a story or something. Or I'll use it to write blog posts; I have a great approach. It's, “Write a blog post about this topic and here are some salient points and do it in the style of Corey Quinn.” I'll ask Chat-Gippity to do that and it spits out something that is, frankly, garbage.And I get angry at it and I basically copy it into a text editor and spent 20 minutes mansplain-correcting the robot. And by the time it's done, I have, like, a structure of an article that talks about the things I want to talk about correctly. And there may be three words in a sequence that were originally there. And frankly, I'm okay with plagiarizing from the thing that is plagiarizing from me. It's a beautiful circle of ripping things off that that's glorious for me.But that's also not something that I could see being useful at any kind of scale, where I see companies getting excited about a lot of this stuff, it all seems to be a thin veneer over, “And then we can fire our customer service people,” which from a labor perspective is not great, but ignoring that entirely, as a customer, I don't want that. Because by the time I have to reach out to a company's customer service apparatus, something has gone wrong and it isn't going to be solved by the standard list of frequently asked questions that I clicked on. It's something that is off the beaten path and anomalous and requires human judgment. Making it harder for me to get to people who can fix those things does not thrill and delight me.David: I agree. I'm with you there. Where I get excited about it, though, is how much of a force multiplier it can be on that human interaction. So, for example, in that customer's service case you mentioned, you know, if that customer service rep is empowered by an AI dashboard that's listening to my conversation and taking notes and automatically looking up in my knowledge base how to support that customer, then that customer success person can be more successful more quickly, I think they can be more responsive to customer needs and maybe improve the quality, not just the volume of work they do but improve the quality, too.Corey: That's part of the challenge, too. There have been a number of companies that have gotten basically rapped across the snout for just putting out articles as content, written by AI without any human oversight. And these don't just include, you know, small, scrappy content mills; they include Microsoft, and I believe CNN, if I'm not mistaken, had something similar with that going on. I'm not certain on that last one. I don't want to defame them, but I know for a fact Microsoft did.David: Yeah, and I think some of the email generators are plugging into AI now, too, because my spam count has gone through the roof lately.Corey: Oh, my God. I got one recently saying, “Hey, I noticed at The Duckbill Group that you fix AWS bills. Great. That's awesome and super valuable for your clients.” And then try to sell me bill optimization and process improvement stuff. And it was signed by the CEO of the company that was reaching out.And then there was like—I expand the signature view, and it's all just very light gray text make it harder to read, saying, “This is AI generated, yadda, yadda, yadda.” Called the company out on Twitter, and they're like, “Oh, we only have a 0.15% error rate.” That sounds suspiciously close to email marketing response rates. “Welp, that means 99% of it was perfect.” No, it means that you didn't get in front of most of those people. They just ignored it without reading it the way we do most email outreach. So, that bugs me a fair bit. Because my perspective on it is if you don't care enough to actually craft a message to send me, why should I care enough to read it?David: Completely agree. I think a lot of people are out there looking for that asymmetric, you know, leverage that you can get over the market, and generating content, to them, has been a blocker for so long and now they're just opening up the fire hose and drowning us all with it. So I'm, like, with you. I think that I personally don't expect to get value back from someone unless I put value into that relationship. That's my starting point coming into it, so I would maybe use AI to help assist forming a message to someone, but I'm not going to blast the internet with content. I just think that's a cheeky low-value way to go about it.Corey: I don't track the numbers anymore, but I know that at this point, through the size of my audience and the content that I put out, I have taken, collectively, millennia of human time focusing on—that has been spent consuming the content that I put out. And as a result of that, I have a guiding principle here, which is first and foremost, you've got to respect your audience. And I'm just going to have a robot phone it in is not respecting your audience. I have no problem with AI assistants, but it requires human oversight before it goes out. I would never in a million years send anything out to the audience that I hadn't at least read or validated first.But yeah, some of the signups that go out, the automatic things that you click a button and sign up for my newsletter at lastweekinaws.com, you get an auto message that comes out. Yeah, it comes out under my name and I either wrote it or reviewed it, depending on what generation of system we're on these days, because it has my name attached to it. That's the way that this works. Your credibility is important and having a robot spout off complete nonsense and you get the credit or blame for it? No thanks. I want to be doomed from my own sins, not the ones that a computer makes on my behalf.David: [laugh]. Yeah, I'm with you. It's unfortunate that so many people expect the emails from you are generated now. We have the same thing when people sign up for Tidal Accelerator or Tidal LightMesh, they get a personal email from me. They'll get the automated one as well, but I generally get in there through our CRM, and I send them a message, too. And sometimes they'll respond and say, “This isn't really David, is it?” No, no, it's me. You don't have to respond. I wanted to let you know that I'm thankful for you trialing our software.Corey: Oh, yeah. You can hit reply to any email I send out. It comes from corey@lastweekinaws.com and it goes to my inbox. The reason that works, frankly, at this scale is because no one does it. People don't believe that that'll actually work. So, on a busy week, I'll get maybe a dozen email replies to it or one or two misconfigured bounces from systems that aren't set up properly to do those things. And I weed those out because they drive me nuts.But it's a yeah, the only emails that I get to that address, honestly, are the test copies of those messages that go out, too, because I'm on my own newsletter list. Who knew? I have two at the moment. I have—yes, I have two specific addresses on that, so I guess technically, I'm inflating the count of subscribers by two, if advertisers ask. But you know, at 32,000 and change, I will take the statistical fudging.David: Absolutely. We all expect that.Corey: No, the depressing part, when I think about that is, there's a number of readers I have on the list that I know for a fact that I've been acquainted with who have passed away. They're never going to unsubscribe from these things until the email starts bouncing at some and undefinable point in the future. But it's also—it feels morbid, but on some level, if I continue doing this for the rest of my life, I'm going to have a decent proportion of the subscriber base who's died. At least when people leave their jobs, like, their email address gets turned off, things start bouncing and cool that gets turned off automatically because even when people leave voluntarily, no one bothers to go through an unsubscribe from all this stuff. So, automated systems have to do it. That's great. I'm not saying computers shouldn't make life better. I am saying that they can't replace a fundamental aspect of human caring.David: So, Corey Quinn, who has influence over the living and the dead. It's impressive.Corey: Oh, absolutely. Honestly, if I were to talk to whoever came up with IBM's marketing strategy, I feel like I'd need to conduct a seance because they're probably 300 years old if they're still alive.David: [laugh]. Absolutely.Corey: No, I get passionate about this stuff because so much of a lot of the hype now has been shifting away from letting people expand their reach further and doing things in intentional ways and instead toward absolute garbage, such as, “Cool, we want to get a whole bunch of clicks so we can show ads to them, so we're going to just generate all bunch of crap to your content and throw it out there.” Everything I write, even stuff that admittedly, from time to time, is aimed for SEO purposes for specific things that we're doing, but that's always done from a perspective of okay, my primary SEO strategy is write compelling, original content and then people presumably link to it. And it works. It's about respecting the audience and so many things get that wrong.David: Yeah, absolutely. It's kind of scary now because I always thought that podcasts and video were the last refuge of authentic content. And now people are generating that as well. You know, you're watching a video and you realize hey, that voice sounds exactly consistent, you know, all the way through. And then it turns out, it's generated. And there's a YouTube channel I follow because I'm an avid sailor, called World On Water. And recently, I've noticed that voice changed, and I'm pretty sure they're using AI to generate it now.Corey: Here's a story I don't think you probably know about yourself. So, for those who are unaware, David, I hang out from time to time in various places. There's a international boundary between us, but occasionally one of us will broach it, and good for us. And we have social conversations where somehow one of us doesn't have a microphone in front of our face. Imagine that. I don't know what that's like most weeks.And like, at some level, the public face comes off and people start acting like human beings. And something I've always noticed about you, David, is that you don't commit the cardinal sin, for an awful lot of people I meet, which is displaying contempt for your customers. When I have found people who do that, I think less of them in almost every case and I lose so much interest in whatever it is that they're doing. If you don't like the problem space that you're in and don't have respect for the people paying you to make these problems go away, you shouldn't be doing it. Like, I'll laugh at silly AWS misconfigurations, but my customers are there because they have a problem and they're bringing me in to fix it. And would I be making fun of? “Ha ha ha, you didn't spend eight months of your life learning the ins and outs of how exactly reserved instances apply in this particular context? What a fool is you.” That's not how it ever works. I wish I could say it wasn't quite as rare as it is but I'm tired of talking to people who have just nothing but contempt for their market. Good work on that.David: Thank you. Yeah, I appreciate that. You know, I had a penny-drop moment when I was doing a lot of consulting work as an independent contractor, working with different customers at different stages of their own journey and different levels of technology capabilities. You know, you work with management, with project people, with software engineers, and you start to realize everybody's coming from a different place. So, you have to empathize with where they're at.They're coming to you usually because you have a level of expertise, that you've got some specialization and they want to tap into that capability that you've created. And that's great. I love having people come to me and ask me questions. Sometimes they don't come to me nicely asking questions, they make some assumptions about me and might challenge me right off the bat, but you have to realize that that's just where they're coming from at that point in time. And once you connect with them, they'll open up a little bit more, too; they'll empathize with yourself. So yeah, I've always found that it's really important for myself personally, but also for our team to empathize with customers, meet them where they're at, understand that they're coming from a different level of experience, and then help them solve their problems. That's job number one.Corey: And I'm a firm believer that if you don't respect your customer's business, they shouldn't be your customer. It's happened remarkably few times in the however many years I've been doing this, but there have been a couple of folks that have reached out I always very politely decline to work with them when this happens. Because you don't want to make people feel obnoxious for reaching out and, like, “Can you help me with my problem?” “How dare you? Who do you think you are?”No, no, no, no, no, none of that. But if there's a value misalignment or I don't think that your product is going to benefit people who use it as directed, I will not let you sponsor what I do as an easy example. Because I can always find another sponsor and make more money, but once I start losing the audience's trust, I'll never get that back, and I know that. It's the entire reason I do things the way that I do them. And maybe, on some level, from purely capitalist perspective, I'm being an absolute fool, but you know, if you have to pick a way to fail and assume you're going to get it wrong, how do you want to be wrong? I'll take this way.David: Yeah, I agree. Keep your ethics high, keep your morals high, and the rest will fall into place.Corey: I love how we started having ethical and morality discussions that started as, “So, cloud migrations. How are they going for you?”David: Yeah [laugh]. Certainly wandered into some uncharted territories on that one.Corey: Exactly. We started off in one place; wound up someplace completely removed from anything we could have reasonably expected at the start. Why? Because this entire episode has been a beautiful metaphor for cloud migrations. I really want to thank you for taking the time to chat with me on this stuff. If people want to learn more, where should they go to find you?David: tidal.cloud or LinkedIn, I'm very active on LinkedIn these days.Corey: And we will, of course, put links to both of those in the show notes. Thank you so much for going down this path with me. I didn't expect it to lead where it did, but I'm glad we went there.David: Like the tides ebbing and flowing. I'll be back soon, Corey.Corey: [laugh]. I will take you up on that and hold you to it.David: [laugh]. Sounds great.Corey: David Colebatch, CEO at Tidal.

David Colebatch, CEO at Tidal.cloud, joins Corey on Screaming in the Cloud to discuss how Tidal is demystifying cloud migration strategy. David and Corey discuss the pros and cons of a hybrid cloud migration strategy, and David reveals the approach that Tidal takes to ensure they're setting their customers up for success. David also discusses the human element to cloud migration initiatives, and how to overcome roadblocks when handling the people side of migrations. Corey and David also expand on all the capabilities cloud migration unlocks, and David explains how that translates to a distributed product team approach.About DavidDavid is the CEO & Founder of Tidal.  Tidal is empowering businesses to transform from traditional on-premises IT-run organizations to lean-agile-cloud powered machines.Links Referenced: Tidal.cloud: https://tidal.cloud Twitter: https://twitter.com/dcolebatch LinkedIn: https://www.linkedin.com/in/davidcolebatch/ TranscriptAnnouncer: Hello, and welcome to Screaming in the Cloud with your host, Chief Cloud Economist at The Duckbill Group, Corey Quinn. This weekly show features conversations with people doing interesting work in the world of cloud, thoughtful commentary on the state of the technical world, and ridiculous titles for which Corey refuses to apologize. This is Screaming in the Cloud.Corey:  LANs of the late 90's and early 2000's were a magical place to learn about computers, hang out with your friends, and do cool stuff like share files, run websites & game servers, and occasionally bring the whole thing down with some ill-conceived software or network configuration. That's not how things are done anymore, but what if we could have a 90's style LAN experience along with the best parts of the 21st century internet? (Most of which are very hard to find these days.) Tailscale thinks we can, and I'm inclined to agree. With Tailscale I can use trusted identity providers like Google, or Okta, or GitHub to authenticate users, and automatically generate & rotate keys to authenticate devices I've added to my network. I can also share access to those devices with friends and teammates, or tag devices to give my team broader access. And that's the magic of it, your data is protected by the simple yet powerful social dynamics of small groups that you trust.Try now - it's free forever for personal use. I've been using it for almost two years personally, and am moderately annoyed that they haven't attempted to charge me for what's become an essential-to-my-workflow service.Corey: Have you listened to the new season of Traceroute yet?

My thanks to them for sponsoring this ridiculous podcast. Corey: Welcome to Screaming in the Cloud. I'm Corey Quinn. Every once in a while at The Duckbill Group, I like to branch out and try something a little bit different before getting smashed vocally, right back into the box I find myself in for a variety of excellent reasons. One of these areas has been for a while, the idea of working with migrations on getting folks into cloud. There's a lot of cost impact to it, but there's also a lot of things that I generally consider to be unpleasant nonsense with which to deal. My guest today sort of takes a different philosophy to this. David Colebatch is the CEO and founder of Tidal.cloud. David, thank you for joining me.David: Oh, thanks for having me, Corey.Corey: Now, cloud migrations tend to be something that is, I want to say contentious, and for good reason. You have all the cloud providers who are ranting that cloud is the way and the light, as if they've just found religion, and yeah, the fact that it basically turns into a money-printing machine for them has nothing to do with their newfound advocacy for this approach. Now, I do understand that we all have positions that we come from that shape our perspective. You do run and did found a cloud migration company. What's your take on it? Is this as big as the cloud providers say it is, is it overhyped, or is it underhyped?David: I think it's probably in the middle of this stage of the hype cycle. But the reason that that Tidal exists and why I founded it was that many customers were approaching cloud just for cloud's sake, you know, and they were looking at cloud as a place to park VMs. And our philosophy as software engineers at Tidal is that customers were missing out on all the new capabilities that cloud provided, you know, cloud is a new paradigm in compute. And so, our take on it is the customer should not look at cloud as a place to migrate to, but rather as a place to transform to and embrace all the new capabilities that are on offer.Corey: I've been saying for a while that if you sit there and run a total cost analysis for going down the path of a cloud migration, you will not save money in the short term, call it five years or whatnot. So, if you're migrating to the cloud specifically to save money, in the common case, it should be for a capability story, not because it's going to save you money off of what you're currently doing in the data center. Agree, disagree, or it's complicated?David: It's complicated, but you're right in one case: you need to work backwards from the outcomes, I think that much is pretty simple and clear, but many teams overlook that. And again, when you look at cloud for the sake of cloud, you generally do overlook that. But when we work with customers and they log into to our platform, what we find is that they're often articulating their intent as I want to improve business agility, I want to improve staff productivity, and it's less about just moving workloads to the cloud. Anyone can run a VM somewhere. And so, I think, when we work backwards from what the customer is trying to achieve and we look at TCO holistically, not just about how much a computer costs to run and operate in a colo facility, look at it holistically from a staff productivity perspective as well, then the business case for cloud becomes very profound.Corey: I've been saying for a while that I can make a good-faith Total Cost of Ownership analysis—or TCO analysis—in either direction, so tell me what outcome you want and I can come up with a very good-faith effort answer that gives you what you want. I don't think I've seen too many TCO analyses, especially around cloud migrations, that were not justification exercises. They were very rarely open questions. It was, we've decided what we want to do. Now, let's build a business case to do that thing. Agree, disagree?David: [laugh]. Agree. I've seen that. Yeah, we again, like to understand the true picture of total cost of ownership on-premises first, and many customers, depending on who you're engaging with, but on the IT side, might actually shield a few of those costs or they might just not know them. And I'm talking about things like in the facilities, insurance costs, utility bills, and things like that, that might not bubble up.We need to get all those cards on the table in order to conduct a full TCO analysis. And then in the cloud side, we need to look at multiple scenarios per workload. So, we want to understand that lift-and-shift base case that many people come from, but also that transformative migration case which says, I might be running in a server-ful architecture today on-premises, but based on the source code and database analysis that we've done, we can see an easy lift to think like Lambda and serverless frameworks on the cloud. And so, when you take that transformative approach, you may spend some time upfront doing that transformation, or if it's tight fit, it might be really easy; it might actually be faster than reverse-engineering firewall rules and doing a lift-and-shift. And in that case, you can save up to 97% in annual OPEX, which is a huge savings, of course.Corey: You said the magic words, lift-and-shift, which means all right, the gloves come off. Let's have this conversation.David: Oh yeah.Corey: I work on AWS bills for a living. Cloud cost and architecture are fundamentally the same thing, and when I start looking at a company's monthly bill, I can start to see the architectural patterns emerge with no further information than what's shown in the exploded bill view, at least at a high level. It starts to be indicative of different things. And you can generally tell, on some level, when companies have come from a data center environment or at least a data center mentality, in what they've built. And I've talked to a number of companies where they have effectively completely lifted their data center into the cloud and the only real change that they have gotten in terms of value for it has been that machines are going down a lot less because the hard drive failed and they were really bad at replacing hard drives.Now, for companies in that position who have that challenge, yeah, the value is there and it's apparent because I promise, whoever you are, the cloud providers are better at replacing failed hard drives than you are, full stop. And if that's the value proposition you want, great, but it also feels like that is just scratching the surface of what the benefit of cloud providers can be.David: Absolutely. I mean, we look at cloud as a way to unlock new ways of working and it's totally aligned with the new distributed product team approach that many enterprises are pursuing. You know, the rise of Agile and DevOps has sort of facilitated this movement away from single choke points of IT service delivery, like we used to with ITIL, into much more modern ways of working. And so, I imagine when you're looking at those cloud bills, you might see a whole host of workloads centered into one or two accounts, like they've just replicated a data center into one or two accounts and lifted-and-shifted a bunch of EC2 to it. And yeah, that is not the most ideal architectural pattern to follow in the cloud. If you're working backwards from, “I want to improve staff productivity; I want to improve business agility,” you need to do things like limit your blast radius and have a multi-account strategy that supports that.Corey: We've seen this as well and born-in-the-cloud companies, too, because for a long time, that was AWS's guidance of put everything in a single AWS account. The end. And then just, you know, get good with IAM issues. Like, “Well okay, I found that developer environments impacted production.” Then, “Sounds like a skill issue.”Great, but then you also have things that cannot be allocated, like service quotas. When you have something in development run amok and exhaust service quotas for number of EC2 get instance info requests, suddenly, load balancers don't anymore and auto-scaling is kind of aspirational when everything explodes on you. It's the right path, but very often, people got there through following the best advice that AWS offers. I am in the middle of a migration myself from the quote-unquote, “Legacy” AWS account, I built a bunch of stuff in 2016 into its own dedicated account and honestly, it's about as challenging as some data center moves that I've done historically.David: Oh, absolutely. I mean, the cobwebs build up over time and you have a lot of dependencies on services, you completely forget about.Corey: “How do I move this S3 bucket to another account?” “That's the neat part. You don't.”David: [laugh]. We shouldn't just limit that to AWS. I mean, the other cloud providers have similar issues to deal with through their older cloud adoption frameworks which are now playing out. And some of those guidance points were due to technology limitations in the underlying platform, too, and so you know, at the time, that was the best way to go to cloud. But as I think customers have demanded more agility and more control over their blast radiuses and enabling self-service teams, this has forced everyone to sort of come along and embrace this multi-account strategy. Where the challenge is, with a lot of our enterprise clients, and especially in the public—Corey: Embrace it or you'll be made to embrace it.David: Yeah [laugh]. We see with both our enterprise accounts that were early adopters, they certainly have that issue with too much concentration on one or two accounts, but public sector accounts as well, which we're seeing a lot of momentum in, they come from a place where they're heavily regulated and follow heavy architectural standards which dictate some of these things. And so, in order for those clients to be successful in the cloud, they have to have real leadership and real champions that are able to, sort of, forge through some of those issues and break outside of the mold in order to demonstrate success.Corey: On some level, when I see a lift that failed to shift, it's an intentional choice in some cases where the company has decided to improve their data center environment at the cost of their cloud environment. And it feels, on some level, like it's a transitional step, but then it's almost a question that I always have is, was this the grand plan? So, I guess my question for you is, when you see a company that has some workloads in a data center and some living in the cloud provider in what most people call hybrid, is that outcome intentional or is it accidental, where midway through, they realize that some workloads are super hard to migrate? They have a mainframe and there is no AWS/400 available for their use, so they're going to give up halfway, declare victory, and yep we're hybrid now. How did they get there?David: I think it's intentional, quite often that they see hybrid cloud as a stepping stone to going full cloud. And this just comes down to project scoping and governance, too. So, many leaders will draw a ring around the workloads that are easy to migrate and they'll claim success at the end of that and move on to another job quite often. But the visionary leaders will actually chart a path to course that has a hundred percent adoption, full data center closure, off the mainframe, off AS/400, you know, refactored usually, but they'll chart that course at a rate of change that the organization can accept. Because, you know, cloud being a new paradigm, cloud requiring new ways of working, they can't just ram that kind of change through in their enterprise in one or two years; they really need to make sure that it's being absorbed and adopted and embraced by the teams and not alienating the whole company as they go through. And so, I do see it as intentional, but that stepping stone that many companies take is also an okay thing in my mind.Corey: And to be clear, I should bound what I'm saying from the perspective that I'm talking about this from a platonic ideal perspective. I am not suggesting that, “Oh, this thing that you built at your company is crappy,” I mean, any more so than anything else is. I've never yet seen any infrastructure that the people running it would step back and say, “This is amazing and perfect.” Everyone thinks it's a burning dumpster fire of sadness and regret and I'm not entirely sure that they're wrong.I mean, designing an architecture—cloud or otherwise—on a whiteboard is relatively straightforward, for a junior employee, even. The problem is most people don't get to start from scratch and build that thing. There's existing stuff that needs to be migrated in and most of us don't get the luxury of taking two years of downtime for that service while we wind up rebuilding it from scratch. So, it's one of those how do you rebuild a car without taking it off the highway to do it type of questions.David: Well, you want to have a phased migration approach, quite often. Your business can't stop and start because you're doing a migration, so you want to build momentum with the early adopters that are easy to migrate and don't require big interruptions to business. And then for those mission-critical workloads that do need to migrate—and you mentioned mainframe and AS/400 before—they might be areas where you introduce, like, a strangler fig pattern, you know, draw a ring around it, start replicating some services into cloud, and then phase that migration over a year or two, depending on your timeline and scale. And so, we're very much pragmatic in this business that we want to make sure we're doing everything for the right reasons, for the business-led reasons, and fitting in migrations around business objectives and strategies is super critical to success.Corey: What I'm curious about is when we talk about migrations, in fact, when I invited you on the show, and it was like, well, Tidal migrations—one thing I love about calling it that for the domain, in some cases, as well as other things is, “Huh, says right in the tin what it is. Awesome.” But it's migrations, which I assumed to be, you know, from data centers into cloud. That's great. But then you've got the question of, is that what your work looks like? Is it migrations in the other direction? Is cloud repatriation a thing that people are doing, and no one bothered to actually ever bother to demonstrate that to me? Is cloud to cloud? What are you migrating from and to?David: Well, that's great. And we actually dropped migrations from the name.Corey: Oh, my apologies. Events, once again, outpace me.David: Tidal.cloud is our URL and essentially, Corey, the business of migration is something that's only becoming increasingly frequent. Customers are not just migrating from on-premises data centers to cloud, they're also migrating in between their cloud accounts like you are, but also from one cloud provider to another. And our business hypothesis here Tidal is that that innovation cycle is continuing to shrink, and so whereas when I was in the data center automation business, we used to have a 10 and 15-year investment cycle, now customers have embraced continuous delivery of their applications and so there's this huge shift of investment horizons, bringing it down to an almost an annual event for many of the applications that we touch.Corey: You are in fact correct. Tidal.cloud does have a banner at the top that says, “Tidal Migrations is now Tidal.” Yep, you're correct, not that I'm here to like incorrect you on the name of your own company, for God's sake. That's a new level of mansplaining I dare not delve into.But it does say, “Migration made modern,” right at the top, which is great because there's a sense that I've always had that lift-and-shift is poo-pooed as a bad approach to migrating, but I've done it other ways and it becomes disastrous. I've always liked the approach of take something in a data center, migrated into cloud, in the process, changing as few things as possible, and then just get it stable and working there, and step two becomes the transformation because if you try and transform while it moves, yeah, that gets you a little closer to outcome in theory, but when things don't work right—and their computers; let's not kid ourselves, nothing works right—it's a question now of was it my changes? Is it the cloud environment? Is there an unknown dependency that assumes things in the data center that are not true in cloud? It becomes very hard to track down the why of these things.David: There's no one-size-fits-all for migration. It's why we have the seven-hour assessment capabilities. You know, if one application, like you've just talked about, that one application might be better to lift and shift than modernize, there might be real business reasons for doing that. But what we've seen over the years is the customers generally have one migration budget. Now, IT gets one migration budget and they get to end a job in a lift-and-shift scenario and the business says, “Well, what changed? Nothing, my apps still run the same, I don't notice any new capabilities.” And IT then says, “Yeah, yeah. Now, we need the modernization budget to finish.” And they said, “No, no, no. We've just given you a bunch of money. You're not getting any more.”And so, that's what quite often the migrate as a lift-and-shift kind of stalls and you see an exodus of talent out of those organizations, people leave to go on to the next migration project elsewhere and that organization really didn't embrace any of the cloud-native changes that were required. We'd like to really say that—and you saw this on our header—that migrations made modern, we'd like to dispel the myth that you can either migrate or modernize. It's really not an either/or. There's a full spectrum of our methods, like replatform, and refactor, rehosting, in the middle there. And when we work backwards from customers, we want to understand their core objectives for going to cloud, their intent, their, “Why cloud?”We want to understand how it aligns on the cloud value framework, so business agility gains, staff productivity gains, total cost of ownership is important, of course. And then for each of their application workloads, choose the right 6R based on those business outcomes. And it can seem like a complicated or comprehensive problem, but if you automate it like we do, you can get very consistent results very quickly. And that's really the accelerant that we give customers to accelerate their migration to cloud.Corey: One thing that I've noticed—and maybe this makes me cynical—but when I see companies doing lift-and-shift, often they will neglect to do the shift portion of it. Because there's a compelling reason to do a migration to get out of a data center and into a cloud, and often that is a data center contract expiry coming up. But companies are very rarely going to invest the time, energy, and money—which all become the same thing, effectively, at company scale—in refactoring existing applications if they're not already broken.I see that all the time in my work, I don't make recommendations to folks very often have the form, “Oh, just migrate this entire application to serverless and you'll save 80% or more on it.” And it's, “That's great, but that's 18 months' worth of work and it doesn't actually get us closer to our business milestones, so yeah, we're not going to do that.” Cost directly is very rarely a compelling reason to make a migration, but when you're rebuilding something for business purposes, factoring cost concerns into it seems to be a much better way to gain adoption and traction of those ideals.David: Yeah, yeah. Counterpoint on that, when we look at a portfolio of applications, like, hundreds or thousands of applications in an enterprise and we do this type of analysis on them with the customers, what we've learned is that they may refactor and replatform ten, 20% of their workloads, they may rehost 40%, and they'll often turn off the rest, retire them, not migrate them. And many of our enterprise customers that we've spoken to have gone through rationalizations as they've gone to cloud and saved, you know, 59%, just turned off that 59% of an infrastructure, and the apps that they do end up refactoring and modernizing are the ones where either there's a very easy path for them, like, the code is super compatible and written in a way that's fitting with Lambda and so they've done that, or they've got, like you said, business needs coming up. So, the business is already investigating making some changes to the application, they already want to embrace CI/CD pipelines where they haven't today. And for those applications, what we see teams doing is actually building new in the cloud and then managing that as an application migration, like, cutting over that.But in the scheme of an entire portfolio of hundreds or thousands of applications that might be 5, 10, 20% of the portfolio. It won't be all of them. And that's what we say, there's a full spectrum of migration methods and we want to make sure we apply the right ones to each workload.Corey: Yeah, I want to be clear that there are different personas. I find that most of my customers tend to fall into two buckets. The first is that you have the born-in-the-cloud SaaS companies, and that's the world I come from, where you have basically one workload that's 80% of your application spend, your revenue, et cetera. Like, they are not a customer, but take Datadog as an example. Like, the Datadog monitoring application suite would be a good example of this, and then you have a bunch of longtail stuff.Conversely, you've got a large enterprise that might be spending $100 million or so every year, but their largest single application is a couple million bucks because it just has thousands upon thousands of them. And at that point, it becomes much more of a central IT planning problem. In one of those use cases, spending significant effort refactoring and rebuilding things, from an optimization perspective, can pay dividends. In other cases, it tends not to work in quite the same way, just because the economies of scale aren't there. Do you find that most of your customers fall into one of those two buckets? Do you take a different view of the world? How do you see the market?David: Same view, we do. Enterprise customers are generally the areas that we find the most fit with, the ISVs, you know, that have one or two primary applications. Born in the cloud, they don't need to do portfolio assessments. And with the enterprise customers, the central IT bit used to be a blocker and impediment for cloud. We're increasingly seeing more interest from central IT who is trying to lead their organization to cloud, which is great, that's a great sign.But in the past, it had been more of a business-led conversation where one business unit within an enterprise wants to branch away from central IT, and so they take it upon themselves to do an application assessment, they take it upon themselves to get their own cloud accounts, you know, a shadow IT move, in a way. And that had a lot of success because the business would always tie it back to business outcomes that they were trying to achieve. Now, into IT, doing mass migration, mass portfolio assessment, this does require them to engage deeply with the business areas and sometimes we're seeing that happening for the very first time. There's no longer IT at the end of a chain, but rather it's a joint partnership as they go to cloud, which is really cool to see.Corey: When I go to Tidal.cloud, you have a gif—yes, that's how it's pronounced, I'm not going to take debates on that matter—but you have a gif at the top of your site a showing a command line tool that runs an analyze command on an application. What are you looking at to establish an application or workload's suitability for migration? Because I have opinions on this, but you have, you know, a business around this and I'm not going to assume that my strongly-held opinions informed by several weeks of work are going to trump, you know, the thing that your entire company is built around.David: Thanks, Corey. Yeah, you're looking at our command-line utilities there. It's an accompanying part of our product suite. We have a web application and the command-line utilities are what customers use behind their firewall to analyze their applications. The data points that we look at are infrastructure, as you can imagine, you might plug into VMware and discover VMs that are running, we'll look for non-x86 workloads on the network.So, infrastructure is sort of bread and butter; everyone does that. Where Tidal differentiates is going up the stack, analyzing source code, analyzing database technologies, and looking at the schema usage within your on-premises database, for example, which features and functionality are using, and then how that fits to more cloud-native database offerings. And then we'll look at the technology age as well. And when you combine all of those technology factors together, we sort of form a view of what the migration difficulty to cloud will be on various migration outcomes, be it rehost, replatform, or refactor.The other thing that we add there is on the business side and the business intent. So, we want to understand from leadership what their intent is with cloud, and there's some levers they pull in the Tidal platform there. But then we also want to understand from each application owner how they think about their applications, what the value of those applications are to them and what their forward-looking plans are. We capture all these things in our tool, we then run it through our recommendation engine, and that's how we come up with a bespoke migration plan per client.Corey: One of the challenges I have in the cost arena around a lot of these tools that oh, we're going to look at your various infrastructure-as-code situation and see what that's going to cost you for a given change. It's like, sure, that that's not hard from a baseline of I want to spin up ten more EC2 instances. Yes, that is the tricky part of cloud economics known as basic arithmetic. The problem where I see is that okay, and then they're going to run Kubernetes, which has no sense of zone affinity, so it's going to wind up putting nondeterministic amounts of traffic across a AZ boundary and that's going to spike data transfer in some use cases, but none of these tools have any conception as to what those workloads look like. Now, that's a purely cost perspective, but that does have architectural approaches. Do you factor things like that in when you move up the stack?David: Absolutely. And really understanding on a Tidal inventory basis, understanding what the intent is of each of those workloads really does help you, from a cloud economics basics, to work out how much is reasonable in terms of cloud costs. So, for example, in Tidal, if you're doing app assessment, you're capturing any revenue to business that it generates, any staff productivity that it creates. And so, you've got the income side of that application workload. When you map that to on-premises costs and then later to cloud costs, your FinOps job becomes a lot easier because now you have the business context of those workloads too.Corey: So, one of the things that I have found is that you can judge the actual success of a project by how many people who work at the company claimed credit for it on LinkedIn, whereas conversely, when things don't work out super well, it's sort of a crickets moment. I'm curious as to your perspective on whether there is such a thing as a migration failure, or is it simply a, “Oh, we're going to iterate on this in a new direction. We've replaced a failing part, which turned out, from our perspective, to be our CIO, but we have a new one who's going to move us into cloud in the proper time and space.” We go through more of those things than some people do underwear. My God. But is there such a thing as a failed cloud migration?David: There absolutely is. And I get your point that success has many fathers. You know, when clients have brought us in for that success party at the end, you don't recognize everybody there. But you know, failure can be, you know, you've missed on time, scope, or budget, and by those measures, I think 76% of IT projects were failing in 2018, when we ran those numbers.So absolutely, by those metrics, there are failed cloud migrations. What tends to happen is people claim success on the workloads that did migrate. They may then kick it out into a new project scope, the organizational change bit. So, we've had many customers who viewed the cloud migration as a lift-and-shift exercise and failed to execute on the organizational change and then months later realized, oh, that is important in order for my day two operations to really hum, and so then have embarked on that under a separate initiative. So, there's certainly a lot of rescoping that goes on with these things.And what we like to make sure we're teaching people—and we do this for free—is those lessons learned and pitfalls with cloud early on because we don't want to see all those headlines of failed projects under that; we want to make sure that customers are armed with here are the things you should consider to execute on as you go to cloud.Corey: Do you ever run an analysis on a workload when a customer is asking, “So, how should we go about migrating this?” And your answer is, “You should absolutely not?”David: Well, all applications can go to cloud, it's just a matter of how much elbow grease you want to put into it. And so, the absolutely not call comes from when that app doesn't provide any utility to the business or maybe it has a useful life of six more months and the data center is going to be alive for seven. So, that's when those types of judgment calls come in. Other times we've seen, you know, there's already a replacement initiative underway by the business. IT wasn't aware of it, but through our process and methodology, they engaged with the business for the first time and learned about it. And so, that helps them to avoid needing to migrate workloads because the business is already moving to Salesforce, for example.Corey: I imagine you're also relatively used to the sinking realization that customers often have when they're used to data center thinking and you ask them a question, like, “How many gigabytes a month does your application server send back and forth to your database server?” And their response, very reasonably, is, “Why on earth would I know the answer to that quest—oh, God. You mean, that's how it bills?” It's the sense of everything is different in cloud, sometimes, subtly, sometimes massively. But it's a different way of thinking.So, I guess my last real big question for you on this is, moving technology is relatively straightforward but migrating people is very challenging. How do you find that the people and the processes that have grown up in data center environments with people whose identities are inextricably linked the technology they work on, being faced with the idea of it is now time to pick up and move these things into an environment where things that were incredibly valuable guardrails in a data center environment no longer serve you well?David: Yeah. The people side of cloud migration is the more challenging part. It's actually one of the reasons we introduced a service offering around people change management. The general strategy is sort of the Kotter change process of creating that guiding coalition, the people who want to do something different, get them outside of IT, reporting out to the executives directly, so they're unencumbered by the traditional processes. And once they start to demonstrate some success of a new way of working, a new paradigm, you kind of sell that back into the organization in order to drive that change.It's getting a lot easier to position that organizational change aspects with customers. There's enough horror stories out there of people that did not take that approach. And quite rightly. I mean, it's tough to imagine, as a customer, like, if I'm applying my legacy processes to cloud migration, why would I expect to get anything but a legacy result? You know, and most of the customers that we talk to that are going to cloud want a transformational outcome, they want more business agility and greater staff productivity, and so they need to recognize that that doesn't come without change to people and change the organization. It doesn't mean you have to change the people out individually, but skilling the way we work, those types of things, are really important to invest in and I'd say even more so than the technology aspects of any cloud migration.Corey: David, I really want to thank you for taking the time to talk to me about something that is, I'd say near and dear to my heart, except I'm trying desperately not to deal with it more than I absolutely have to. If people want to learn more, where's the best place for them to find you?David: Sure. I mean, tidalcloud.com is our website. I'm also on Twitter @dcolebatch. I like to tweet there a little bit, increasingly these days. I'm not on Bluesky yet, though, so I won't see you there.

Inside Story’s Tim Colebatch says three Victorian seats are seen as “pretty certain” wins for Labor - Dunkley, Corangamite and Chisholm. A number of others “are really open” - Casey, La Trobe, Deakin, Flinders and possibly even Higgins. “It does strike me that [the Liberals] they’ve done a lot to show the flag in Victoria. Morrison has been down there frequently”. Colebatch tells The Conversation climate change is a big factor in many of the blue ribbon Victorian electorates. “The failure of the government to tackle climate change is a real drawback for the Liberals when they try and confront an electorate like this, because it’s full of an educated and wealthy people who understand that we have to do something and don’t mind the cost of doing it.” On the Senate, Colebatch thinks it will have fewer crossbenchers because of the larger vote needed in a half-Senate election; he says it will be particularly hard for the minor parties of the right to get in.

From inside the budget lockup, The Conversation’s Business and Economics editor Peter Martin and political and economic journalist Tim Colebatch from Inside Story shared their reactions to the pre-election budget. Martin said the budget featured a substantial tax cut “that goes back in time” and that while the government was forecasting “good times around the corner,” there has been barely any sign of them. He also said he thought while the budget gives Labor an advantage, Treasurer Josh Frydenberg is unlikely to be embarrassed by it in the future. Colebatch told The Conversation it “was a modest budget” and that the spending measures were “really fairly restrained”. “It recognises that the debate has shifted and people are less likely to be bought by big spending and more likely to be bought by the impression of fiscal reticence and control and delivering a budget surplus,” he said.
