Virtual Private Server
A Virtual private server (VPS) is a type of web hosting server where hosting is done by segregating a main physical server into multiple virtual servers. Each server in the system gets their part of resources based on custom requirements. Each part of this VPS has capabilities of performing independent operations with its own operating system and hardware resources dedicated to it. These resources are completely saturated from the other servers on the same platform. VPS offers great choice of customization and flexibility to manage and restructure resource unlike its counterpart of dedicated server.
Virtual private servers are commonly used in web hosting services, where they are useful for segregating customer accounts, pooling resources and containing any potential security breaches. To save space on such installations, each virtual server's file system can be created as a tree of copy-on-write hard links to a "template" file system. The hard link is marked with a special filesystem attribute and when modified, is securely and transparently replaced with a real copy of the file.
