Virtual Private Server?
Abbreviated as VDS, a virtual dedicated server is a type of virtualization that enables a virtual server, which is a shared resource and not a dedicated server, to to work and act as if it were a dedicated server. Each VDS has its own disk space, bandwidth, CPU allocation, memory and operating system. Also called a virtual private server (VPR).
Server virtualization is the partitioning of a physical server into smaller virtual servers to help maximize your server resources. In server virtualization the resources of the server itself are hidden, or masked, from users, and software is used to divide the physical server into multiple virtual environments, called virtual or private servers. This is in contrast to dedicating one server to a single application or task.
