The process of virtualization in computing environments involves creating virtual versions of physical hardware resources, such as servers, storage devices, or networks. This is accomplished using a hypervisor, which sits between the hardware and the operating systems, allowing multiple virtual machines (VMs) to run simultaneously on a single physical system. Virtualization enhances resource allocation and optimizes the use of hardware capabilities, enabling greater efficiency, scalability, and flexibility within IT infrastructures. It also simplifies the management of resources and can support dynamic workloads, making it a crucial technology in modern computing.
