Kubernetes

cgroups (abbreviated from control groups) is a Linux kernel feature that limits, accounts for and isolates the resource usage (CPU, memory, disk I/O, network, etc.) of a collection of processes. 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.
