27. What is the architecture of Kubernetes?
The architecture of Kubernetes consists of following components:
Master : There is a master node that is responsible for managing the cluster. Master performs following functions in a cluster.
I. Scheduling Applications
II. Maintaining desired state of applications
III. Scaling applications
IV. Applying updates to applications
Nodes : A Node in Kubernetes is responsible for running an application. The Node can be a Virtual Machine or a Computer
in the cluster. There is software called Kubelet on each node. This software is used for managing the node and communicating
with the Master node in cluster.
There is a Kubernetes API that is used by Nodes to communicate with the Master. When we deploy an application on
Kubernetes, we request Master to start application containers on Nodes.
