VPS – Virtual Private Server. If you rent VPS service, your services will be on VPS, which is on a powerful dedicated server. VPS functions independently from each other. So if there are a few VPS on one physical server, they do not influence functioning of each other. Each virtual server gets its own dedicated resources. The owner of VPS gets a full access (root) to own virtual server and can work with it like with a separate physical server. It will also help to install any additional applications, modules and services. It will also help to do any suitable settings of all programs. In case you use VPS the Virtual servers share the resources of their physical server – its processors, RAM and network bandwidth. In such a way, VPS-hosting gives you full access and control of your server and practically the same advantages as the physical server has. And at the same time the price of a virtual server is much lower than of a dedicated server, and its productivity is higher than the productivity when using a virtual hosting.
