Virtualization

Virtualization is splitting hardware resources so that multiple virtual machines can use them. Virtualization can be of two types. Virtualization can ether be as an application or as a hypervisor. Hypervisor acts as own operating system.

Part of system resources are allocated to a virtual machine, so if you have resource intensive application such as database then it is a bad candidate for virtualization.

Good candidates for virtualization are web servers, mail servers, etc. Careful analysis of utilization needs to be done before virtualization.

A benefit of virtualization is that hardware resources are virtualized making it easier to transfer applications from host to host.

Two common applications for virtualization are VirtualBox and VMWare. VirtualBox is an application that can be installed in an OS.
