# Node

Describe about Node

A `Node` is a computer, either virtual , cloud or physical, where Kubernetes runs. A bunch of nodes together forms a `Cluster`. \
\
In K8s It has 2 kind of Node 

1. **Master Node**
2. **Worker Node**

**Master Node**

It will use the `Kube API Server` to manage and monitor the `worker node`. Also, the `Worker Node` will rebalance itself in the situation of a failure. It 's possible to has multiple **Master Node** in the cluster. 

**Worker Node**

It will operate on the Node after getting the command from the Master Node via Kubelet.
