A thin layer of software called a hypervisor decouples the virtual machines from the host and dynamically allocates computing resources to each VM as needed. Putting multiple VMs on a single computer enables several operating systems and applications to run on just one host machine. Software executed on a virtual machine is separated from the underlying hardware resources. Each self-contained VM is completely independent. Businesses can run more than one virtual system – and multiple operating systems and applications - on a single physical server, known as the host. Virtualization uses software to simulate the existence of hardware and create a virtual computer system or virtual machine (VM) that acts like an actual computer. Virtualization helps simplify IT management, reduce capital and operating costs, minimize downtime and ensure business continuity. Workloads get deployed faster, performance and availability increase, and operations can become automated in a virtualized environment. Virtualization can also increase IT agility, flexibility and scalability. ![]() Virtualization has become the most effective way for businesses of all sizes to reduce IT expenses and increase efficiency. Applications, servers, desktops, storage devices and networks can all be virtualized. Virtualization is the process of creating a software-based, virtual representation of a physical IT resource.
