Way of using resources In the case of shared hosting, websites and / or applications residing on the server make use of resources and available server capacity at the same time. In the case of VPS hosting, each websites and / or applications residing on the server is being allotted a virtually distinct server.  Here a separate, exclusive server is often rented.
A VPN server is a machine on the internet that runs VPN software. A VPN client can connect to that server, and all data that travels between the client and the server is encrypted. If you wanted to connect to a website on the internet but didn’t want anyone, even your ISP, to see which site it was or the data your were sending, you could connect via a VPN. All an observer would be able to see is that you connected to the VPN server.
A VPS runs its own copy of an operating system (OS), and customers may have superuser-level access to that operating system instance, so they can install almost any software that runs on that OS. For many purposes they are functionally equivalent to a dedicated physical server, and being software-defined, are able to be much more easily created and configured. They are priced much lower than an equivalent physical server. However, as they share the underlying physical hardware with other VPSes, performance may be lower, depending on the workload of any other executing virtual machines.[1]
