VPS clients become their own administrators and, therefore, they gain access to many admin functions from which they would be excluded with shared web hosting. This means that users can control all aspects of their VPS service; however, this also means that they are leaving the system more exposed to the chances of viruses and malware entering the system. It also means that end-users may carry out actions that could have a deleterious effect on the VPS operating system.
The VPS operating system runs its own copy operating system, enabling users to install a great variety of software to run on the operating system. You find that some VPS companies do have certain restrictions as to what can and cannot be installed, but normally the user has much greater scope compared to straightforward, shared web hosting.
The software—programs and data running—on each VPS hosting service, have been configured so that they can be rebooted by the client, because they are set up to serve the needs of a single client.
