Kubernetes is an open-source container orchestration platform used for running distributed applications and services at scale. The control plane (master node) is the most crucial part of the cluster. The API server is a crucial component of the control plane that exposes the API and interfaces for deploying and managing the complete lifecycle of containers. It is the front-end server that is responsible for managing internal and external requests, then processes the request to run on the end of the request. The master node manages the scheduling of pods across different nodes within the cluster keeping into account the available resources on each Node.
