Virtualization is the migration of physical systems to a virtual environment, creating virtual copies of each device or asset, from servers to operating systems. With a virtual preview of computing resources it is possible to change one server into a host for a group of servers which share the same assets.
Virtualization enables immediate access to almost unlimited computing resources which translates to broader business opportunities and reduction of overall costs of IT and hardware.
The most important function of virtualization is the possibility of starting multiple operating systems and application on a single computer or server. This means increased efficiency achieved in fewer servers. Virtualization may improve the overall performance of applications by balancing assets and delivering only what is currently necessary to the user.
