Containers implementations

Although this document is focused on docker we must clarify that there are different containers implementations.

LXC (Linux Containers)

This is the father of all kinds of containers and it represents an operating-system-level virtualization environment for running multiple isolated Linux systems (containers) on a single Linux machine. You can get more information Click Here

OpenVZ

This is an OS-level virtualization technology based on the Linux kernel and the operating system. OpenVZ allows a physical server to run multiple isolated operating system instances, called containers, virtual private servers (VPSs), or virtual environments (VEs).

Lmctfy

This was by Google to compete with docker but it was not a success.

The FreeBSD jail

This is a mechanism that implements an OS-level virtualization, which lets the administrators partition a FreeBSD-based computer system into several independent mini-systems called jails. The AIX Workload partitions (WPARs) These are the software implementations of the OS-level virtualization technology, which provide application environment isolation and resource control.

Solaris Containers (including Solaris Zones)

This is an implementation of the OS-level virtualization technology for the x86 and SPARC systems. A Solaris Container is a combination of the system resource controls and boundary separation provided by zones. Zones act as completely isolated virtual servers within a single operating system instance.
