cgroups (a backronym for control groups) is a Linux kernel feature to limit, account, and isolate resource usage (CPU, memory, disk I/O, etc.) of process groups. This work was started by engineers at Google (primarily Paul Menage and Rohit Seth) in 2006 under the name “process containers”. In late 2007, it was renamed to “Control Groups” due to the confusion caused by multiple meanings of the term “container” in the Linux kernel, and merged into kernel version 2.6.24. Since then, many new features and controllers have been added, such as support for kernfs, firewalling, and the introduction of a unified hierarchy. – Wikipedia
LXC is a userspace interface for the Linux kernel containment features. Through a powerful API and simple tools, it lets Linux users easily create and manage system or application containers. – LXC
An open platform for distributed applications for developers and sysadmins. – Docker
