Answer
A cluster has a Control Plane that manages state and Worker Nodes that run Pods.
Quick Answer
A cluster has control plane nodes (the brain — API server, scheduler, etcd, controller manager) and worker nodes (the muscle — where your apps run). The control plane makes decisions; worker nodes execute them. In production, you typically have 3 control plane nodes for high availability and as many workers as your workload needs.
