Docker

Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications.

http://www.zdnet.com/article/what-is-docker-and-why-is-it-so-darn-popular/

Developers can use Docker to pack, ship, and run any application as a lightweight, portable, self sufficient LXC container that can run virtually anywhere.

In a nutshell, here's what Docker can do for you: It can get more applications running on the same hardware than other technologies; it makes it easy for developers to quickly create, ready-to-run containered applications; and it makes managing and deploying applications much easier.

http://en.wikipedia.org/wiki/LXC

LXC (Linux Containers) is an operating system–level virtualization method for running multiple isolated Linux systems (containers) on a single control host.

LXC provides operating system-level virtualization through a virtual environment that has its own process and network space, instead of creating a full-fledged virtual machine.

The Docker Engine uses Linux-specific kernel features, so to run it on Windows we need to use a lightweight virtual machine (vm).
