Virtualisation
Virtualisation is a framework or methodology of dividing the resources of a computer into multiple execution environments, by applying one or more concepts or technologies such as hardware and software partitioning, time-sharing, partial or complete machine simulation, emulation, quality of service, and many others. Virtualisation is a technique for hiding the physical characteristics of computing resources to simplify the way in which other systems, applications, or end users interact with those resources. Virtualisation lets a single physical resource (such as a server, an operating system, an application, or storage device) appear as multiple logical resources; or making multiple physical resources (such as storage devices or servers) appear as a single logical resource
Benefits
- Reduced costs due to a lower number of physical servers
- Increase utilization efficiency of physical hardware
- Reduction in power, space and cooling requirements providing a greener infrastructure
- Greatly enhance an organisation's business agility
