 A Kubernetes cluster consists of two types of resources:
 
-
 * The **Control Plane** coordinates the cluster
 * **Nodes** are the workers that run applications

 **The Control Plane is responsible for managing the cluster.** The Control Plane
 coordinates all activities in your cluster, such as scheduling applications, maintaining
 applications' desired state, scaling applications, and rolling out new updates.

 **A node is a VM or a physical computer that serves as a worker machine in a Kubernetes
 cluster.** Each node has a Kubelet, which is an agent for managing the node and
 communicating with the Kubernetes control plane. The node should also have tools for
 handling container operations, such as {{< glossary_tooltip text="containerd" term_id="containerd" >}}

 When you deploy applications on Kubernetes, you tell the control plane to start
 the application containers. The control plane schedules the containers to run on
