Virtual Private Servers (VPS)

Virtual private server (VPS) is a term used for emphasizing that the virtual server, although running in software on the same physical computer as other customers' virtual machines, is functionally equivalent to a separate physical computer, is dedicated to the individual customer's needs, has the privacy of a separate physical computer.

In addition to reducing hardware and power expenditures, virtualisation allows businesses to run their legacy applications on older versions of an operating system on the same server as newer applications.

Each virtual server can run its own full-fledged operating system and can be independently rebooted.

The practice of partitioning a single server so that it appears as multiple servers has long been common practice on mainframe computers and mid-range computers such as the IBM AS/400. It has become more prevalent with the development of virtualization software and technologies for microcomputers.
