Virtual private server

Virtual private servers or Virtual dedicated servers are a form of virtualization that split a single physical server into multiple virtual servers. The practice of partitioning a single server so that it appears as multiple servers has long been common practice in mainframe computers, but has seen a resurgence lately with the development of software and  technologies such as VMware, Xen, FreeBSD Jail, User-mode Linux, Linux-VServer, FreeVPS, OpenVZ, and Virtuozzo.
