Virtualization is a technique of separating the service from the underlying physical delivery of that service. It is the process of creating a virtual version of something like computer hardware. It was initially developed during the mainframe era. It involves using specialized software to create a virtual or software-created version of a computing resource rather than the actual version of the same resource. With the help of Virtualization, multiple operating systems and applications can run on the same machine and its same hardware at the same time, increasing the utilization and flexibility of hardware. In other words, one of the main cost-effective, hardware-reducing, and energy-saving techniques used by cloud providers is virtualization. In this video, we are going to discuss the concept of Virtualization in Cloud Computing in detail along with its various prominent benefits.
