What is virtualisation?

Virtualisation is a new technique that enables you to disconnect physical hardware from an administration system. In this way you can put several “virtual servers” in one physical subdivision. You can also put one virtual server on several physical subdivisions. With virtualisation resources like processors, disk space and memory can be used more efficiently and flexibility will increase.

Using virtualisation causes virtual environments with different systems to work isolated and separately on one or several physical machines. Every virtual environment has its own set of virtual hardware (disk space, memory, processors, network card etc.) where a system and applications or working on. The system has a consistent set of hardware, no matter the real physical hardware components.

Whole environments (with configured applications, systems, BIOS and virtual hardware) can be moved from one physical machine to another without interruptions for “zero-downtime” administration and continuously division of the load.

One of the main leading figures in virtualisation is Vmware. Nxs Internet is with its application of its Vmware ESX cluster one of the first authorised hosting providers of the Netherlands.
