The Ultimate Guide to Virtualisation
Virtualisation is everywhere in the information technology space because it is so useful. It refers to the ‘virtual’ creation of a computer, a network, a storage system, or anything else, rather than a physical one. A physical device can contain multiple virtual ones, in other words, each instance of which can have different settings and capabilities. With powerful hardware, the value of virtualisation is quickly apparent: one physical device can contain multiple virtual instances, delivering greater flexibility and fulfilling multiple tasks. Virtual machines offer other advantages, including security and scalability, allowing systems administrators to adjust their computing estate to meet varying levels of demand.
