And the components on the bottom…togeather can be called data plane. At this level,…a simplistic view is where data plane runs your containers…and applications, and is controlled by the control plane.…

You rarely interact with the data plane directly.…Let's take a look at a more Kubernetes-centric view of this.…Lets look at the control plane first.…The control plane consists of a master node. The Kubernetes…master is responsible for maintaining the desired…state of your cluster. The master itself, refers to a…collection of processes, managing the cluster state,…which we will discuss in a second.…
