What is server virtualization?
Most computer systems use hardware, an operating system and software applications. As a result the software application is linked to the server hardware.
Virtualization breaks that link. A component of virtualization software, the hypervisor, is located between the hardware and the operating system. Because of the hypervisor the operating system and software applications can run independently of the physical hardware.
Virtual servers
Thanks to the virtualization software it is possible to run various virtual servers on a physical server. The modern, powerful hardware makes it possible to install up to 20 virtual servers on one physical server.

Quick migration
Because of the fact that the link between the software application and the physical environment is broken, virtual servers can be easily migrated to other server hardware without any downtime.
It is also possible to do maintenance activities or expand server resources without interrupting the applications running on the servers.
