Virtual Private Server (VPS) and Virtual Private Server (VDS) are both types of virtual server. A virtual server is a computer that is used to provide a virtual space on the Internet for users.
A virtual server is also sometimes called a virtual hosting server.
A virtual server can be run on a physical server, or it can be run on a virtual machine.
The main difference between VPS and VDS is that a VPS is a dedicated server while a VDS is a shared server. A dedicated server is one that is specifically configured for your needs and is not shared with other users.
A shared server is one that is shared with other users.
