Kubernetes is a portable, extensible, open-source platform for managing containerized workloads and services, across a distributed cluster of nodes. Kubernetes provides a resilient infrastructure that ensures high availability, scaling, and automatic rollback. Kubernetes clusters consist of a set of nodes, which run containerized applications. 

A cluster is a functional Kubernetes deployment, which is secure, extendable, and customizable from a configuration file. A node may be a virtual or a physical machine, depending on your cluster.  Each node runs pods, which are made up of containers. Every cluster has at least one worker node, which hosts the pods that comprise the application workload. The control plane manages the worker nodes and the pods within the cluster.
