Virtualization is the process of creating a virtual version of something, such as a server, a storage device, a network, or even an operating system where the framework divides the resource into one or more execution environments. Distinctly separated from the physical hardware, it allows multiple virtual instances to run simultaneously on a single machine. Virtualization is widely used in web hosting for efficiency, scalability, and better resource management, enabling the hosting of multiple virtual servers on a single physical server.
