Virtual private server (VPS) is the method of dividing or splitting a physical server so that it serves multiple websites. In this case one computer can have several of these Servers, each one with its own Operating system (OP) that runs the hosting software for a particular user. Each of this server can run its own operating system and can be rebooted on its own. Most times it serves as a dedicated server to the user because it gives independence on shared servers.
When installed, it runs a program that boots each virtual server within a virtualization environment. The hosting software for each this server may include a file transfer protocol program (FTPP), a mail server and some specialized applications for some activities such as blogging. It has covered the gap between shared web hosting and dedicated hosting services but at a cheaper cost. Due to the increased number of users, dedicated server has a limited processor time, RAM and disk space. The ability of a single subscriber to maintain multiple virtual servers is also a useful advantage and aspect of virtual private server. Most upcoming companies, offer this service as an additional web hosting service while some companies even call it a dedicated server. It also serves as an alternative server for small businesses or companies that need a modified website server but cannot afford a dedicated server. It is obviously cheaper and gives maximum satisfaction.
