A VPS eliminates the restrictions of shared hosting by giving you the power and flexibility of a dedicated sever with your own set of services and customizable disk space. Shared hosting is limited in comparison because its users do not have administrative access and software configurations cannot be customized, despite the fact that physical resources are also multiplexed. With a VPS, you can control your own unique file system and CGI-BIN, disk space, system resources, bandwidth and memory allotments. VPS users control a lot of the settings on the server thus getting customized environment for website and server needs.
