Kubernetes Design and Components

Kubernetes, which is also known as k8s, is a platform for managing containers. It is a complex system focused on the complete life cycle of containers, including configuration, installation, health checking, troubleshooting, and scaling. With Kubernetes, it is possible to run microservices in a scalable, flexible, and reliable way. Let's assume you are a DevOps engineer at a fin-tech company, focusing on online banking for your customers.

You can configure and install the complete backend and frontend of an online bank application to Kubernetes in a secure and cloud-native way. With the Kubernetes controllers, you can manually or automatically scale your services up and down to match customer demand. Also, you can check the logs, perform health checks on each service, and even SSH into the containers of your applications.

In this section, we will focus on how Kubernetes is designed and how its components work in harmony.
