The containerization in Docker is achieved via resource isolation (cgroups), kernel names spaces (isolating the application’s view of the OS, process trees, etc) and a union-capable file system (such as aufs – mounting multiple directories into one that appears to contain their combined contents). Using containers removes the overhead of having to create, deploy and maintain full VMs for running your applications. As well as providing completely identical PROD, Staging, QA, DEV environments. In some cases you can even move a container from one server to another, making it ideal to spin a quick instance of your PROD environment on a separate server to do a quick test without messing with the actual PROD environment.
