Docker -- wiki

Docker (software)

 http://en.wikipedia.org/wiki/Docker_(software)

Docker is an open-source project that automates the deployment of applications inside software containers, by providing an additional layer of abstraction and automation of operating system–level virtualization on Linux.[2] Docker uses resource isolation features of the Linux kernel such as cgroups and kernel namespaces to allow independent "containers" to run within a single Linux instance, avoiding the overhead of starting virtual machines.[3]

Linux kernel's namespaces completely isolate an application's view of the operating environment, including process trees, network, user IDs and mounted file systems, while cgroups provide resource isolation, including the CPU, memory, block I/O and network. Docker includes the libcontainer library as a reference implementation for containers, and builds on top of libvirt, LXC (Linux containers) and systemd-nspawn, which provide interfaces to the facilities provided by the Linux kernel.[4][5]
According to industry analyst firm 451 Research, "Docker is a tool that can package an application and its dependencies in a virtual container that can run on any Linux server. This helps enable flexibility and portability on where the application can run, whether on premise [sic], public cloud, private cloud, bare metal, etc."[6]
