A Virtual Private Server (VPS) provides all the features of a Dedicated Server, only it exists on a machine that is shared by other web hosting clients. As a result, customers get the same type of hosting services that are available with dedicated hosting without sacrificing performance or privacy.
A VPS is much less expensive than a dedicated server, with many of the same advantages. By using a method of partitioning a single physical server into many unique servers, a VPS has the appearance and capabilities of being run on its own dedicated server. Similar to dedicated servers, each virtual server can run its own operating system, and can be rebooted independent of other servers on the same physical system.
The physical server boots itself normally, then runs a virtualization program which boots each VPS individually. Each virtual server is usually booted from a disk image, and has not direct access to the hardware.
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 virtualization software and technologies for other architectures.
The physical server boots normally. It then runs a program that boots each virtual server within a virtualization environment (similar to an emulator). The virtual servers have no direct access to hardware and are usually booted from a disk image.
A growing number of hosting companies are now offering VPS hosting, or virtual dedicated server hosting, as an extension of their existing service offerings.
