Docker
Docker is a containerisation technology that allows you to run multiple lightweight Linux-based environments (containers) that are separated from each other in a way similar to virtual machines.
Containers are much easier to manager and a lot quicker to start or stop thanks to their reliance on the single Linux kernel (of your Docker host server) and a few isolation technologies like namespaces and cgroups.
There are a few limitations compared to classical VMs, but also quite a few advantages.
Docker for CentOS distribution is available for free Community Edition (CE) and as a subscription in Enterprise Edition (EE) and can be installed on bare metal or cloud infrastructure.
