Learn to create containerized applications, manage deployments across infrastructures, and prepare for advanced Kubernetes concepts.

Kubernetes Essentials

Kubernetes helps us deploy and manage containerized applications at scale. It abstracts the underlying infrastructure of applications, meaning it doesn’t matter if we deploy our applications to Amazon Web Services, Google Cloud, Linode, or our own on-premises datacenter.

In this module, we’ll learn what Kubernetes is,  why we need it,  how it's expected to change, and how we can use it to create containerized applications. By the end of this module, we will be ready to tackle more advanced concepts and take our Kubernetes skills to the next level.
