Virtual private server, or VPS, represents the next generation of web hosting that revolves around partitioning a single computer to simulate multiple servers. The unique aspect is that each server has the look and feel of a physical server, equipped with its own operating system and the ability to be rebooted independently of others. Similar practices have actually been used in mainframe computers for some time, but the emergence of virtualization technology has pushed VPS hosting into the mainstream market as a cost efficient, high performance solution.
