What is virtualization?
Virtualization is a solution that allows multiple "different operating systems" to be installed and executed simultaneously on a hardware system. Virtualization provides the ability to isolate hardware from an operating system, which makes it possible to make optimal use of IT resources, more flexibility, and hardware independence. Several virtual machines with the same or different operating system can be installed together on the same hardware, each with its own hardware. In this case, the virtual operating system can continue to operate, regardless of the hardware
