What are virtual servers?

A virtual server is a server created by software called a hypervisor. The virtual server runs on top of a physical ‘host’ server and shares the host’s CPU, RAM, storage, networking, and other hardware resources. Virtual servers offer various benefits over physical servers, including cost-efficiency and on-demand provisioning. They are also known as ‘virtual private servers (VPS), ‘virtual machines’, or simply ‘VMs’.
