00:05In this lesson, let us look at OCI container instances.
00:10Containers have become the favored method of packaging, deploying, and managing modern applications.
00:16Meet Alex.
00:17Alex wants to test his containerized application but without deploying it on OKE as the scale is not large.
00:25At the same time, the applications he wants to containerize are running isolated web applications or RESTful APIs.
00:32He is looking for a simple, quick, and secure way to run containers without managing any servers.
00:40When you want a simple way to run a containerized application without using Kubernetes,
00:46you can provision a virtual machine, install a container runtime, and run your applications on it as is shown in the diagram here.
00:54However, this process still increases the operational complexity as you need to manage the VMs and the servers,
01:03patch the operating system, and update the container runtime regularly.
01:08So, what is the solution?
01:09OCI has a capability called OCI container instances, and these container instances offer the quickest and most straightforward way to launch containers
01:20without the need to handle virtual machines or adopt more advanced services like OKE.
01:26By eliminating the operational complexity, OCI container instances enable users to run containerized applications without having to manage any infrastructures.
01:37Users only need to supply the container image for their applications, and OCI takes care of the underlying container runtime and compute resources.
01:47You can specify environment variables, resource limits, startup options, etc. for each container,
01:54and you can even run multiple containers on one container instances.
01:58The containers are hosted on fully managed compute infrastructure that is specifically designed for container workloads,
02:06providing robust workload isolation for enhanced security.
02:11So, that's it.
02:12Think of container instances as a serverless offering where you can run containers without really worrying about the underlying infrastructure.
