During this series of informative podcasts, we'll bring you foundational training on the most popular Oracle technologies. Let's get started! 00:25 Lois: Hello and welcome to the Oracle University Podcast! I'm Lois Houston, Director of Innovation Programs with Oracle University, and with me is Nikita Abraham, Team Lead: Editorial Services. Nikita: Hi everyone! For the last two weeks, we've been talking about different aspects of cloud data centers. In this episode, Orlando Gentil, Principal OCI Instructor at Oracle University, joins us once again to discuss how virtualization, through hypervisors, virtual machines, and containers, has transformed data centers. 00:58 Lois: That's right, Niki. We'll begin with a quick look at the history of virtualization and why it became so widely adopted. Orlando, what can you tell us about that?  Orlando: To truly grasp the power of virtualization, it's helpful to understand its journey from its humble beginnings with mainframes to its pivotal role in today's cloud computing landscape. It might surprise you, but virtualization isn't a new concept. Its roots go back to the 1960s with mainframes. In those early days, the primary goal was to isolate workloads on a single powerful mainframe, allowing different applications to run without interfering with each other. As we moved into the 1990s, the challenge shifted to underutilized physical servers. Organizations often had numerous dedicated servers, each running a single application, leading to significant waste of computing resources. This led to the emergence of virtualization as we know it today, primarily from the 1990s to the 2000s. The core idea here was to run multiple isolated operating systems on a single physical server. This innovation dramatically improved the resource utilization and laid the technical foundation for cloud computing, enabling the scalable and flexible environments we rely on today. 02:26 Nikita: Interesting. So, from an economic standpoint, what pushed traditional data centers to change and opened the door to virtualization? Orlando: In the past, running applications often meant running them on dedicated physical servers. This led to a few significant challenges. First, more hardware purchases. Every new application, every new project often required its own dedicated server. This meant constantly buying new physical hardware, which quickly escalated capital expenditure. Secondly, and hand-in-hand with more servers came higher power and cooling costs. Each physical server consumed power and generated heat, necessitating significant investment in electricity and cooling infrastructure. The more servers, the higher these operational expenses became. And finally, a major problem was unused capacity. Despite investing heavily in these physical servers, it was common for them to run well below their full capacity. Applications typically didn't need 100% of server's resources all the time. This meant we were wasting valuable compute power, memory, and storage, effectively wasting resources and diminishing the return of investment from those expensive hardware purchases. These economic pressures became a powerful incentive to find more efficient ways to utilize data center resources, setting the stage for technologies like virtualization. 04:05 Lois: I guess we can assume virtualization emerged as a financial game-changer. So, what kind of economic efficiencies did virtualization bring to the table? Orlando: From a CapEx or capital expenditure perspective, companies spent less on servers and data center expansion. From an OpEx or operational expenditure perspective, fewer machines meant lower electricity, cooling, and maintenance costs. It also sped up provisioning. Spinning a new VM took minutes, not days or weeks. That improved agility and reduced the operational workload on IT teams. It also created a more scalable, cost-efficient foundation which made virtualization not just a technical improvement, but a financial turning point for data centers. This economic efficiency is exactly what cloud providers like Oracle Cloud Infrastructure are built on, using virtualization to deliver scalable pay as you go infrastructure.  05:09 Nikita: Ok, Orlando. Let's get into the core components of virtualization. To start, what exactly is a hypervisor? Orlando: A hypervisor is a piece of software, firmware, or hardware that creates and runs virtual machines, also known as VMs. Its core function is to allow multiple virtual machines to run concurrently on a single physical host server. It acts as virtualization layer, abstracting the physical hardware resources like CPU, memory, and storage, and allocating them to each virtual machine as needed, ensuring they can operate independently and securely. 05:49 Lois: And are there types of hypervisors? Orlando: There are two primary types of hypervisors. The type 1 hypervisors, often called bare metal hypervisors, run directly on the host server's hardware. This means they interact directly with the physical resources offering high performance and security. Examples include VMware ESXi, Oracle VM Server, and KVM on Linux. They are commonly used in enterprise data centers and cloud environments. In contrast, type 2 hypervisors, also known as hosted hypervisors, run on top of an existing operating system like Windows or macOS. They act as an application within that operating system. Popular examples include VirtualBox, VMware Workstation, and Parallels. These are typically used for personal computing or development purposes, where you might run multiple operating systems on your laptop or desktop. 06:55 Nikita: We've spoken about the foundation provided by hypervisors. So, can we now talk about the virtual entities they manage: virtual machines? What exactly is a virtual machine and what are its fundamental characteristics? Orlando: A virtual machine is essentially a software-based virtual computer system that runs on a physical host computer. The magic happens with the hypervisor. The hypervisor's job is to create and manage these virtual environments, abstracting the physical hardware so that multiple VMs can share the same underlying resources without interfering with each other. Each VM operates like a completely independent computer with its own operating system and applications.  07:40 Lois: What are the benefits of this? Orlando: Each VM is isolated from the others. If one VM crashes or encounters an issue, it doesn't affect the other VMs running on the same physical host. This greatly enhances stability and security. A powerful feature is the ability to run different operating systems side-by-side on the very same physical host. You could have a Windows VM, a Linux VM, and even other specialized OS, all operating simultaneously. Consolidate workloads directly addresses the unused capacity problem. Instead of one application per physical server, you can now run multiple workloads, each in its own VM on a single powerful physical server. This dramatically improves hardware utilization, reducing the need of constant new hardware purchases and lowering power and cooling costs. And by consolidating workloads, virtualization makes it possible for cloud providers to dynamically create and manage vast pools of computing resources. This allows users to quickly provision and scale virtual servers on demand, tapping into these shared pools of CPU, memory, and storage as needed, rather than being tied to a single physical machine. 09:10 Oracle University's Race to Certification 2025 is your ticket to free training and certification in today's hottest technology. Whether you're starting with Artificial Intelligence, Oracle Cloud Infrastructure, Multicloud, or Oracle Data Platform, this challenge covers it all!

What's your take? Orlando: A container packages an application in all its dependencies, like libraries and other binaries, into a single, lightweight executable unit. Unlike a VM, a container shares the host operating system's kernel, running on top of the container runtime process. This architectural difference provides several key advantages. Containers are incredibly portable. They can be taken virtually anywhere, from a developer's laptop to a cloud environment, and run consistently, eliminating it works on my machine issues. Because containers share the host OS kernel, they don't need to bundle a full operating system themselves. This results in significantly smaller footprints and less administration overhead compared to VMs. They are faster to start. Without the need to boot a full operating system, containers can start up in seconds, or even milliseconds, providing rapid deployment and scaling capabilities. 11:12 Nikita: Ok. Throughout our conversation, you've spoken about the various advantages of virtualization but let's consolidate them now.  Orlando: From a security standpoint, virtualization offers several crucial benefits. Each VM operates in its own isolated sandbox. This means if one VM experiences a security breach, the impact is generally contained to that single virtual machine, significantly limiting the spread of potential threats across your infrastructure. Containers also provide some isolation. Virtualization allows for rapid recovery. This is invaluable for disaster recovery or undoing changes after a security incident. You can implement separate firewalls, access rules, and network configuration for each VM. This granular control reduces the overall exposure and attack surface across your virtualized environments, making it harder for malicious actors to move laterally. Beyond security, virtualization also brings significant advantages in terms of operational and agility benefits for IT management. Virtualization dramatically improves operational efficiency and agility. Things are faster. With virtualization, you can provision new servers or containers in minutes rather than days or weeks. This speed allows for quicker deployment of applications and services. It becomes much simpler to deploy consistent environment using templates and preconfigured VM images or containers. This reduces errors and ensures uniformity across your infrastructure. It's more scalable. Virtualization makes your infrastructure far more scalable. You can reshape VMs and containers to meet changing demands, ensuring your resources align precisely with your needs. These operational benefits directly contribute to the power of cloud computing, especially when we consider virtualization's role in enabling cloud and scalability. Virtualization is the very backbone of modern cloud computing, fundamentally enabling its scalability. It allows multiple virtual machines to run on a single physical server, maximizing hardware utilization, which is essential for cloud providers. This capability is core of infrastructure as a service offerings, where users can provision virtualized compute resources on demand. Virtualization makes services globally scalable. Resources can be easily deployed and managed across different geographic regions to meet worldwide demand. Finally, it provides elasticity, meaning resources can be automatically scaled up or down in response to fluctuating workloads, ensuring optimal performance and cost efficiency. 14:21 Lois: That's amazing.

Elasticsearch wechselt wieder zu einer Open Source-Lizenz, gleichzeitig ist die zukünftige Pflege der Linux-Manpages ungewiss. Fedora 41 Beta, Ubuntu 24.04.1 und GNOME 47 erscheinen. VirtualBox 7.1 steht im Schatten einer großen Lizenzänderung und mit HeliumOS gibt es eine neue Distribution.

This week we muse on upcoming Raspberry Pi products, prompted by confirmation from Ubuntu that the CM5 is imminent. Then Torvalds has thought on Rust in Linux, Wind River has thoughts on Red Hat, and AWS gives OpenSearch away. Don't miss the non-update on Wireguard, the DirectX surprise, and the long-awaited merge of the Real Time Linux patches!

This week Senator Kevin Cramer joins The Ask Noah Show and we discuss net neutrality! It's a more complicated and nuanced issue than most people give it credit for. Our access to the internet these days is like running water. -- During The Show -- 01:50 Senator Kevin Cramer Interview Common Carrier - treat all traffic equally Net Neutrality - ISPs must treat all traffic equally History 1934 Title 2 1980 Computer 2 Policy 2002 Cable Broadband gets an exemption 2005 All ISPs ARE NOT common carrier 2015 ISPs ARE Common Carrier (Gov Take Over) 2017 Ajit Pai repeals net neutrality If the infrastructure has been subsidized by tax dollars, should that infrastructure be common carrier? Would it make more sense for this to be under the FTC rather than the FCC? What would you say to people who only have one good choice for internet? Ma Bell Sweet Heart deal Chevron doctrine Openness principles throttling blocking price discrimination Blocking World of War Craft ISP deals with apartment complexes to block other providers Digital divide Universal Service Funds ISPs are independent businesses What stops companies from putting smaller players in the "slow lane" Bot Question - Also, aren't the ISP's notorious for promising expanding broadband in the past, but they deem arbitrary numbers as "enough" for consumers, yet countries like Sweden & South Korea are thriving with broadband putting the US to shame. What impact if any do you believe net neutrality would have on ISP competition? Do you think the Communications Act needs a complete overhaul to bring it in line with today's technology? Should the federal or state government step in to break up local monopolies that are not serving their customers well? 42:00 Expand pfSense VLAN? - John PFSense "automatic fix" Subnet masking check for a /24 reboot networking devices 47:38 Virtual pfSense? - Rhett This works!

The STiffs return to podcasting after a very long week. The cloud has changed, Loop still isn't a thing, Viva and Entra are around, and Linux Mint vs Windows 11! Extended show notes available at https://hthpc.com Boot-up (AKA, "LAST WEEK, ON HOPE THIS HELPS") It would be fun to do a "since we've been gone" run through of a high level overview of all of the things in tech that have happened… Some things have changed, while others have stayed the same Microsoft Teams External Access Flaw Poses a Malware Risk Phishing emails Red Hat in the hot seat Jeff Geerling: I'm done with Red Hat (Enterprise Linux) A Comprehensive Analysis of the GPL Issues With the Red Hat Enterprise Linux (RHEL) Business Model Loop (or: Loop: A Fiasco) Loop vs OneNote vs Notion vs Whiteboard vs Miro A Referendum on the Cloud in 2023 Correction: Multi-cloud talk was in HTH0041, not HTH0042. It used to be all cloud, then it was hybrid, then it was multi-cloud, now we're going back to on-premise? Hey: We're Leaving The Cloud Annoying Teams thing of the week: "You'll need to shorten your message to send it" I was pasting an Excel table, two columns, 53 cells Yet you can post huge chunks of code far longer than that? Microsoft Viva Las Vegas Tiff is saving an Entra story for next time… Stuff Tiff pasted into the HTH0042 show notes but we never got to discussing: Create a profile container with Azure Files and Azure Active Directory SharePoint Framework Client-Side Web Part Samples Windows 11 Thoughts on Windows 11 Zune Software in Windows 11 Linux Mint What the heck is up with the TPM requirements? Skip_TPM_Check_on_Dynamic_Update.cmd Feature updates called “moments” Co-Pilots Windows Co-Pilot, GitHub Co-Pilot, etc. GitHub Co-Pilot's tendencies to suggest other people's code without credit or licensing Remember Cortana? The end of Windows? Windows 11 Cloud The Year(s) of Linux In January 2022, Steve moved to Linux on his main desktop - Linux Mint So far, nearly every app, feature, and core experience made the jump without much fuss Linux Mint is very Windows-like OneNote on the web just isn't there yet. I have a VM to run the Windows version (it doesn't work in Wine) Mini-state of the Zunion: It's capable of browsing files on a connected Zune device, USB passthru to VirtualBox works Teams on Linux needs work Asks for a login every time Input/output sound devices get confused during calls - unusable Just use teams.microsoft.com in a browser Steam/Proton is fantastic for gaming Should you do it? If you're willing to put up with learning fast and researching community fixes Most Microsoft-based stuff will work on Linux, with the exception of OneNote which is stuck being web-based (or use a VM) Outro - "Plus Delta" We help you, you help us: Rate us on iTunes

We have no email but we do discuss some of the week's news in an episode that includes a discussion about Mead, Bourbon, Beer, and Moonshine!  News: Harman Kardon Citation MultiBeam 1100 soundbar boasts Dolby Atmos audio Roku welcomes Apple Music to its lineup Alexa can tell you when your security camera detects a person or package Wyze takes on Ecobee, Nest with new room sensors for its smart thermostat 5 mistakes everyone makes with LG OLED TVs, and how to fix them Thanks to their irresistible combination of futuristic, super-slim designs and consistently outstanding picture quality, LG OLED TVs have become the darlings of the high-end TV world – they're not only among the best OLED TVs, but the best TVs of any kind. The problem is that few TVs are set up to deliver their best possible viewing experience out of the box, so if you haven't picked the right settings, you're not getting the most from your TV. So let's look here at some of the most common set up mistakes LG OLED owners make that may be stopping them from getting the viewing experience they deserve. Full article here… Cheat Sheet for Insteon Replacement with HomeAssistant (2.0)  Like many I was shocked to see my Insteon hub with a permanent red light and my expensive IOT  devices inoperative.   A good number of ex-Insteon users are looking to other implementations of home management system  and I soon discovered that HomeAssistant does work with Insteon Devices. The help pages are well done and explain the procedures well. I am back up and running with HomeAssistant following the  instructions, but it is not simple and here are some of the fine points.  The definitive solution involves either the HomeAssistant server hardware or a Rasberry Pi with the  software installed. You can run the system using Virtual system implement ations such as Microsofts's  Hyper-V or VirtualBox.   I suggest you try Virtual Box before you decide to buy dedicated hardware. I found the Hyper-V  unusable, as I have with other implementations, but the VBox works… though was not stable enough in  my hands for a permanent install.  So with Ara's financing I bought a Raspberry Pi on Amazon with the additional bits and pieces you NEED:  mico-SD card for the system; mini-HDMI connector for a display as well as getting a mouse and  keyboard to attach and of course an ethernet cable. Here are the nice install instructions:  https://www.home-assistant.io/installation/raspberrypi/  The set-up is self generated and you really just follow the questions.   If you did this right, the home screen will appear on any web browser populated by a lot of devices you never thought you had, including the hub..  Each of these will then show up on your home screen which is your interface, as well as on your smart  phone. My goal was to get the cameras that I use in my astronomical observatory to work, which I did https://www.astrobin.com/users/jerryyyyy/  There are many viable “canned” interfaces and contingency programming and the home page is entirely  customizable… I am still learning and a real time sink. The biggest problem is initializing some devices. The hub interface seems worthless as it never showed  all my devices and I basically had to add them back in one by one. I made a spreadsheet with the MAC  address and set fixed IP addresses for many… If you do not know what I am talking about when I  mention MAC addresses or IP addresses, you will be in trouble because you need to mess with your  router and set up “fixed IP addresses” for some devices… also cameras have BOTH Wi-Fi and Ethernet  MAC Addresses… On the other hand, if you know what I am talking about, this is a piece of cake.  My to-do list:  Get the motion sensor up and running (Appears to be impossible).  See if there is a way to pan work the cameras (Maybe learning more Python).  Get the GPS location off my iPhone into the system… yes you can get this through the App.  Find some good models for home pages and automations… there are tons but hard to choose.  The one I have is pretty basic.  Bottom line, all in all this is a viable option if you are familiar with the basics of networking.  Essential Afterthought: How to back-up your installation. I learned that to shut down the Pi you do not  pull the power cord… you go to the Linux shell and “sudo halt” luckily my install came back after that  adventure. You can backup and reinstall the SD card contents using Win32 Disk Imager:  https://sourceforge.net/projects/win32diskimager/  If you put this system together, you do not want to lose it!  

Hello,  and welcome to the Third Tech@Lunch Snack episode. The snack episodes are smaller episodes where we cover a singular topic in less than 15 minutes, so you the listener can listen to them when you are taking a break, getting coffee, or having a snack. This week's Snack topic is Why Can't I Virtualize this. In this episode, we look into the world of visualization. We cover the range of Virtualization options during this snack and what some of the benefits are.  We cover VMware, VirtualBox, and portions of Amazon Web services. We attempt to bring awareness to what virtual appliances have to offer and how they can be used and why we think it is a good idea to learn them. So join us as we dive into Why Can't I Virtualize this.

This is a wild one, folks. Matt and Tyler talk about all sorts of things. They start off with a bitch session about Gnome. Then move on to talking about why there seems to be a divide between the level of interest in Linux and Open Source in America and Europe.

Sponsor Circle CI Episode on CI/CD with Circle CI Show DetailsIn this episode, we cover the following topics: VMs vs containers - why revisit?Originally talked about this in episode 1 Got most of it right, but some inconsistencies/holes Let's revisit to fill in the gaps, and dive a whole LOT deeper this time around Types of virtualization Full virtualization ("virtual machines") Simulates enough hardware to allow an unmodified "guest" OS to be run in isolation Resources of computer are partitioned via hypervisor Examples:VMWare, Parallels, VirtualBox, Hyper-V Operating-system-level virtualization ("containers") Resources of computer are partitioned via the kernel"Guest" OSes share same running instance of OS as the host system Based on the virtualization, isolation, and resource management mechanisms provided by the Linux kernelnamespaces and cgroups Examples:Docker, LXC, FreeBSD jails Hypervisors Also known as a Virtual Machine Manager (VMM) Creates and runs virtual machines It is a process that separates OS and apps from underlying physical hardware Multiple VMs share virtualized hardware resources When you create a new VM, the following happens: Hypervisor allocates memory and CPU space for VMs exclusive use Complete OS is installed onto the VM The VM's OS communicates with the hypervisor to perform tasks Host OS is able to see all physical hardware, whereas guest OS (VM) can only see hardware to which hypervisor has granted access Two types of hypervisors Type 1 (also called "native" or "bare metal" hypervisors) Run directly on the host's hardware to control the hardware and manage the guest VMsruns in ring 0 Are an OS themselves (simple OS on top of which you run VMs)the physical machine the hypervisor is running on serves only for virtualization purposesExceptions: Hyper-V, KVM ExamplesXen, Microsoft Hyper-V, VMware ESX/ESXi Type 2 (also called "hosted" hypervisors) Run on conventional OS, just like other apps Guest OS runs as a process on the host Hypervisor separates the guest OS from the host OS ExamplesVirtualBox, Parallels Protection levels (rings) x86 family of CPUs provide a range of protection levels also known as rings Ring 0 has the highest level privilege (kernel/supervisor) Ring 3 lowest level (applications) Hypervisor occupies ring 0 of CPU Kernels for any guest operating systems running on the system must run in less privileged CPU rings But most OS kernels are written explicitly to run in ring 0 Techniques to deal with this: Full virtualization hypervisor provides CPU emulation to handle ring 0 operations made by unmodified guest OS kernels emulation process requires both time and system resourcesinferior performance Paravirtualization Technique in which hypervisor provides an API and the OS of the guest VM calls that API Requires guest OS to be modified (to make API calls)Replace any privileged operations that will only run in ring 0 of the CPU with calls to the hypervisor ("hypercalls") Allows tasks to run in host OS (instead of in guest OS where performance would be worse) Hardware virtualization Requires a CPU with hardware virtualization extensions, such as Intel VT or AMD-VIntel virtualization (VT-x) Virtual Machine Extensions Adds ten new instructions VMPTRLD, VMPTRST, VMCLEAR, VMREAD, VMWRITE, VMCALL, VMLAUNCH, VMRESUME, VMXOFF, and VMXON. These instructions permit entering and exiting a virtual execution mode where the guest OS perceives itself as running with full privilege (ring 0), but the host OS remains protected. Reduces/eliminates any OS modifications in guest OS Provides an additional privilege mode above ring 0 in which the hypervisor can operateessentially leaving ring 0 available for unmodified guest OSes Better performance than paravirtualization Links Virtual machine Hypervisor What is a hypervisor?
