A virtual private server works by having a physical server divided into multiple virtual machines (VMs) which run completely independently and isolated from one another. In this sense, a virtual private server acts and runs just like a physical server – in fact, the operating system on a virtual server does not know it is running in a visualized environment: as far as the operating system is concerned, it is running on a physical server.

The physical server runs special software that allows it to host virtual machines with computing resources like RAM and CPU being isolated in a way which means other virtual machines on the same physical server cannot access the resources which are being used by others. In other words, virtual servers are as secure as a physical server and offer much greater performance than any shared hosting environment.
