3.2 - Virtualisation

The General Reference
By -
Virtualisation is the creation of a virtual version of a device.

There are many pros and cons to virtualisation:

Virtualisation is cheaper as money is saved on buying multiple pieces of hardware
Software can run in a secure environment to ensure it is safe
Virtualisation can be complex to set up
If the physical system goes wrong, so will the connected virtual systems

Many types of devices can be virtualised:

Storage Virtualisation: The combination of storage devices so they appear as a single device
Server Virtualisation: The separation of a single storage device so it appears as multiple devices
Client Virtualisation: When a computer system operates remotely from a separate computer
