Virtualization has been around for quite a long time. It has evolved from a technology used mainly to save space into a corporate strategy adopted worldwide. It is the most effective way to improve IT efficiency while cutting costs.
In order to simulate the underlying hardware and build a virtual computer, virtualization uses software called Hypervisor. It abstracts physical hardware to provide resources such as processors, storage, and networks for workloads. Abstraction enables the system to host multiple workloads simultaneously, leading to resource optimization, which in turn helps you cut down on cost, energy, and space.
The software layer (hypervisor), traditionally called the virtual machine monitor, provides the layer of abstraction. It handles requests between the physical and virtual resources and manages the support of virtual machines. It enables multiple operating systems to share the same hardware, and it allocates what portion of hardware resources each workload should get.
