LXC

LXC (Linux Containers) is an operating-system-level virtualization environment for running multiple isolated Linux systems (containers) on a single Linux control host. The Linux kernel comprises cgroups for resource isolation (CPU, memory, block I/O, network, etc.) that does not require starting any virtual machines. The kernel also provides namespace isolation to completely isolate applications’ view of the operating environment, including process trees, network, user IDs and mounted file systems. LXC combines cgroups and namespace support to provide an isolated environment for applications. Docker can also use LXC as one of its execution drivers, enabling image management and providing deployment services.
