Web hosting is a service which is used to publish website over the internet. Different types of web hosting servers are used to host different types of websites. Initially there were small basic websites and to host them shared hosting plan was introduced, in shared hosting plan one has to share its server resources with others. But as the web technology gets better people developed complex websites for personal as well as for business purposes and in order publish those complex websites one need more stable and reliable web hosting server.

Later on to fulfill the requirements of complex business websites various hosting plans were introduced which mainly include virtual private server (VPS) and dedicated server hosting. In VPS hosting one don’t have to share entire server, various virtual dedicated servers are created on a single physical server on the basis of software and each VDS is independent of other which means it partly act as shared and dedicated server. Using VPS you have various options such as you can choose an operating system (OS), control panel and can modify other aspects of server according to your requirements. VPS provide an efficient traffic control as it use scaling technique. Whenever there is a rise in traffic it automatically scales up and obtains additional server resources in order to fulfill traffic needs and when traffic gets to a normal level it also scales down and left extra resources. It is a bit more costly then shared hosting server but less costly then dedicated server hosting, so people with limited budget websites prefer to choose VPS hosting instead of dedicated server hosting.
