Pasted from RH: OVERVIEW
The Docker project provides the means of packaging applications in lightweight containers. Running applications within Docker containers offers the following advantages: - *Smaller than VMs*: Because Docker images contain only the content needed to run an application, saving and sharing is much more efficient with Docker containers than it is with virtual machines (which include entire operating systems) - *Improved performance*: Likewise, since you are not running an entirely separate operating system, a container will typically run faster than an application that carries with it the overhead of a whole new virtual machine. - *Secure*: Because a Docker container typically has its own network interfaces, file system, and memory, the application running in that container can be isolated and secured from other activities on a host computer. - *Flexible*: With an application's run time requirements included with the application in the container, a Docker container is capable of being run in multiple environments.
