Cluster
A Kubernetes cluster consists of a set of nodes. Of those, a small number are master nodes, which are collectively known as the control plane, and a relatively larger number of worker nodes, which run the cluster's workload.
Node
A node can be a master or worker.
Control Plane
The control plane is the cluster's set of master nodes. The control plane exposes the API via the API Server and contains the cluster store, controller manager, scheduler and other management components.
