Virtual Machines are great, and very useful when trying out new software. However, they might be an unnecessarily heavyweight solution when testing clusters, especially if these consist of multiple nodes running exactly the same software.

Docker is a wrapper around LXC, it automates the deployment of applications inside containers.
