How is virtualization defined in IT?

Virtualization in IT refers to the creation of a virtual version of resources such as servers, storage devices, networks, or operating systems. This process allows multiple virtual instances to run on a single physical hardware setup, enabling greater flexibility, scalability, and optimization of resources. By abstracting physical hardware, virtualization provides the capability to allocate resources more efficiently, create isolated environments for testing and development, and reduce hardware costs.

The concept is crucial in cloud computing and modern data center management, as it allows for easier deployment and management of applications and services while improving overall system resilience and recovery options. This definition encompasses various techniques, including server virtualization, desktop virtualization, and storage virtualization, all aimed at maximizing resource utilization and providing robust IT solutions.
