A VPS hosting is an intermediary option between dedicated and virtual hosting. Such an option is virtually the only option for users, the sites of whom produce great load on the server, however buying a dedicated server is not required or off the budget.

A VPS hosting is providing a certain amount of the server system resources to a user. E.g., the user is assigned a certain amount of processor MHzs, Mbs of operative memory, etc. Moreover, the client does not need to worry how much his site load the server.

Such a hosting is the best solution for projects, related to, let's say, stats collection or provision of resource demanding services.
