VPS Web Hosting or Dedicated Server Hosting
VPS hosting is a more affordable form of dedicated web hosting. Dedicated Web hosting is an option favored by website owners who prefer to have fuller control over the environment under which their website operates. For example, they can choose the server hardware, operating system and server applications.
Because dedicated hosting involves setting aside one physical server machine exclusively for the use of one client, web hosting service providers typically charge much higher for this option compared to shared hosting. Under shared hosting, service providers can host websites from, say hundreds of customers on a single machine.
In Virtual Private Server or VPS hosting, one physical machine can create several virtual machines, each of them a complete environment independent of each other. Each VPS hosting client can choose the operating system and applications, and also choose to administer the server themselves. The administration, whether done by the client or hosting service provider, can include rebooting the system without affecting the other virtual machines of the same physical machine.
The practice of segmenting one physical machine into several virtual machines was earlier available only for bigger machines like mainframes. It has now become available for microcomputers which are typically used by Web servers. Latest virtualization software along with advances in chip technology has made this possible.
Because several virtual servers can be made available by investing in only one physical machine, web hosting service providers can afford to offer VPS hosting services at costs lower than dedicated hosting services. Clients of VPS hosting, on their part, enjoy practically all the advantages of dedicated hosting such as greater control and privacy. The availability of dedicated hosting features at the significantly lower virtual private hosting plans is making it a popular choice for website owners.
