Overview

Containers contain functions for software components, a container can be a web server, a data processor or an data I/O device, anything really that you used to be able to run on a bare metal server or a VM. Containers can run on multiple servers in multiple locations.
Kubernetes provides an open-source API that controls how and where those containers will run, and manages continer failure and restarts.
