By creating multiple resources from a single computer or server, virtualisation improves scalability and workloads while resulting in the use of fewer overall servers, less energy consumption and less infrastructure costs and maintenance.
There are four main categories virtualisation falls into.
- Desktop virtualisation, which allows one centralised server to deliver and manage individualised desktops.
- Network virtualisation, designed to split network bandwidth into independent channels to then be assigned to specific servers or devices.
- Software virtualisation, which separates applications from the hardware and operating system.
- Storage virtualisation, which combines multiple network storage resources into a single storage device where multiple users may access it.
