A Virtual Private Server (VPS), also referred to as Virtual Dedicated Server (VDS), provides the features of a dedicated server for multiple web hosting customers in the form of "virtual computers". At first blush it sounds somewhat contradictory - how can you have a dedicated server if it is being shared by multiple users? Isn't that a regular shared or virtual hosting environment? It is true that with a Virtual Private Server you still share system resources like the CPU and RAM with other users but the resources are allocated in such a way that you cannot tell that the system has anyone else on it, much like a dedicated server. So resources are usually setup in such a way that each hosting client is only allowed to use an allocated percent, meaning that resources assigned to you will always available to you. Each virtual server looks and acts like a dedicated server.
