Linux containers allow multiple applications to run in isolation on a single Linux host using process-level virtualization through kernel features like namespaces and cgroups. Containers use fewer resources than virtual machines since they share the same Linux kernel and are lighter weight. Docker is a popular tool for automating the creation, deployment and management of containers, allowing containers to be easily shared and migrated across servers.

2. LINUX CONTAINER
 Container is letting one kernel to run different
application on a host than VM tries the same objective
on running deferent kernels on a host. Simply Container
uses process level virtualization by use of custom
kernels.
Successors : Solaris Zones
BSD jails
