Using virtualization in Linux is accomplished through the use of a hypervisor, such as VMWare, Virtual Box, or Virtual Machine Manager. Virtualization allows one to run small Virtual Machines (VMs) on one server platform and they each exhibit the functionality and performance of physical servers, yet are virtual. Containers are not actual servers; that is to say, not in the same way one would typically think of servers.

By increasing portability and using fewer system resources than traditional virtual4 machines, containers make ap
