Virtual Private Server concept is not a new one. The idea of dividing the resources of a physical server is being in use from many years. The idea is to divide the Mainframes ( slice up physical server into virtual or “private ) to allow more people affordable access to such huge and very costly devices, where each private server has it’s own unique file system, user space (including virtual root) disk space, process space, CPU, bandwidth, and memory allocations. Even though there limit on CPU, Memory there is no affect on other virtual private server in case of still a horde of heavy traffic. With a Virtual private Server account most important thing that you get Root access to individual private servers and these Private Servers are invisible to each other and do not share processes. Also each virtual private server has its own set of IP add and even in case of faults in one private server, it does not affect others.

The isolation performances eliminate the risk of downtime which may cause by others mistakes, or in case of fault and hack. In short within the fraction of the cost with a virtual private server you get all benefits of a dedicated server as you can share a physical server and still have the same guarantees of a dedicated server.
