Virtualisation
What is Virtualisation?
Virtualisation is one of the most significant recent advances in business technology.
In basic terms it refers to software which 'virtually' creates multiple servers out of one single physical server. Each virtual machine is able to interact independently with other applications and users as though it were a separate physical resource. The technology removes the limitations of the traditional IT approach thereby allowing a business to maximise upon its hardware investment and to realise considerable savings in energy consumption and administration/maintenance costs. Organisations are able to remain safe in the knowledge that if one machine crashes it does not affect the others, due to each virtual machine being isolated from other virtualised machines.
Host software ('Hypervisor') is the unique software component which makes virtualisation possible. It sits between the hardware and the virtual machines and presents a 'virtual' set of hardware to all other software running on the machine, convincing each operating system that it has exclusive access to a particular set of hardware. It not only manages the flow of information between the software, the virtualised hardware and the physical hardware but also controls the amount of access which the operating system and applications have with the processor and other hardware resources such as memory and disk access.
The technology can be applied to a range of other facilities including desktop and storage virtualisation which further improves the resilience and flexibility of the network.
