Because you only are using a portion of the resources for the VM, you can have several of them running on one computer or server, as is common with hosting services. A hosting provider that offers VPS hosting has a vast number of physical servers that each contain multiple virtual machines. While demarcation and intrusion prevention within the physical machine is not a huge concern on your own PC, VPS hosts must have security safeguards in place to ensure isolation of each customer’s server. That’s why the terminology virtual private server is used – to denote the attention paid to privacy and the server programs that are typically loaded onto this type of VM.
A key aspect of VPS internet hosting is its virtualization capabilities. With VPS, the hosting provider divides each physical server into multiple smaller virtual servers with private and dedicated RAM and hard drive space. This provides site owners with a more isolated hosting environment without disruptions from other clients sharing server space.
A virtual server and a dedicated server differ by the number of users that possess resources on a physical server. With a virtual private server, some of the resources are isolated for individual users, but there are multiple users on the same physical server. With a dedicated server, a single user has access to all of the resources of a physical server.

The force driving server virtualization is similar to that which led to the development of time-sharing and multiprogramming in the past. Although the resources are still shared, as under the time-sharing model, virtualization provides a higher level of security, dependent on the type of virtualization used, as the individual virtual servers are mostly isolated from each other and may run their own full-fledged operating system which can be independently rebooted as a virtual instance.
