A VServer is a virtual server.
You can think of a server as a computer, with the virtual server the computer is virtually divided into smaller units. Each unit has its own operating system installed.
You can now easily install the software you want to have on your server. From databases to game servers, there are countless applications that you can install. The advantages of the VServer are the high flexibility and the lower price than the dedicated server, because it is only a part of a dedicated server. Many providers have flexible extensions, so the Vserver can be extended simply by clicking.
If the booked performance is no longer sufficient, you can book an extension in no time without having to set up the server again.
