Kubernetes (aka K8s) is an open-source platform used to run and manage containerized applications and services on clusters of physical or virtual machines across on-premises, public, private, and hybrid clouds. This virtualization makes it possible to efficiently deploy and securely run a container independently of the hosting infrastructure.
