Kubernetes Essentials

“Kubernetes in Practice” is our one-stop shop to learn how to build, deploy, scale, and manage Kubernetes with a step-by-step process.

We'll explore key concepts of Kubernetes with hands-on practice, including architecture, pods, deployments, services, and Ingress. Once the fundamentals are out of our way, we can put your skills to work. We’ll do this through a project where we will create and run an application in a real Kubernetes cluster.

By the time we finish this module, you will have complete confidence in our deployment and management of Kubernetes clusters.

Kubernetes in Practice

In the beginning, there was **monolith** architecture. It was easy to deploy and easy to keep it running. We had only one thing (or a few) to keep an eye on. The monolith was not usually deployed very frequently. At the end of a release cycle, the development team would hand the operations team a package. The operations team would deploy and monitor this application to a handful of servers and make sure it was running smoothly. If some of these servers failed, the operations team would manually move the application to the remaining healthy servers.

But it was not perfect.

Get introduced to the history of deployment and Microservice-based architectures.
