During this series of informative podcasts, we’ll bring you foundational training on the most popular Oracle technologies. Let’s get started! 00:26 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, Principal Technical Editor. Nikita: Hi everyone! Welcome to a new season of the Oracle University Podcast. This time around, we’re going to delve into the world of OCI Container Engine for Kubernetes, or OKE. For the next couple of weeks, we’ll cover key aspects of OKE to help you create, manage, and optimize Kubernetes clusters in Oracle Cloud Infrastructure. 00:58 Lois: So, whether you’re a cloud native developer, Kubernetes administrator and developer, a DevOps engineer, or site reliability engineer who wants to enhance your expertise in leveraging the OCI OKE service for cloud native application solutions, you’ll want to tune in to these episodes for sure. And if that doesn’t sound like you, I’ll bet you will find the season interesting even if you’re just looking for a deep dive into this service. Nikita: That’s right, Lois. In today’s episode, we’ll focus on concepts of containerization, laying the foundation for your journey into the world of containers. And taking us through all this is Mahendra Mehra, a senior OCI instructor with Oracle University. 01:38 Lois: Hi Mahendra! We’re so glad to start our look at containerization with you today. Could you give us an overview? Why is it important in today's software world? Mahendra: Containerization is a form of virtualization, operates by running applications in isolated user spaces known as containers. All these containers share the same underlying operating system. The container engine, pivotal in containerization technologies and container orchestration platforms, serves as the container runtime environment. It effectively manages the creation, deployment, and execution of containers. 02:18 Lois: Can you simplify this for a novice like me, maybe by giving us an analogy? Mahendra: Imagine a container as a fully packaged and portable computing environment. It's like a digital suitcase that holds everything an application needs to run—binaries, libraries, configuration files, dependencies, you name it. And the best part, it's all encapsulated and isolated within container. 02:46 Nikita: Mahendra, how is containerization making our lives easier today? Mahendra: In olden days, running an application meant matching it with your machine's operating system. For example, Windows software required a Windows machine. However, containerization has rewritten this narrative. Now, it's ancient history. With containerization, you create a single software package, a container that gracefully runs on any device or operating systems. What's fascinating is that these containers seamlessly run while sharing the host operating system. The container engine is like a shadow abstracted from the host operating system with limited access to underlying resources. Think of it as a super lightweight virtual machine. The beauty of this, the containerized application becomes a globetrotter, seamlessly running on bare metal within VMs or on the cloud platforms without needing tweaks for each environment. 03:52 Nikita: How is containerization different from traditional virtualization? Mahendra: On one side, we have traditional virtualization. It’s like having multiple houses on a ...
