Virtualisation software allows a modern computer to replace several older computers and run all of the individual programs at the same time without them interfering with each other. Each copy of an operating system or computer program installed on a computer system using virtualisation thinks it has all of the computer resources to itself. In reality the virtualisation software or ‘HyperVisor software’ is juggling it’s time between lots of different tasks in much the same way that parents and teachers have to when looking after a group of young children. Unlike young children, most computer programs do need undivided attention, all of the time, so sharing resources is not only possible, but is also an extremely smart, efficient and cost effective way of working. Most larger companies have policies of putting all new computer system on ‘Virtual Servers’, unless a good reason can be provided for dedicating a whole computer to a single task.
