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.
Virtualization makes use of software called Hypervisor to simulate the underlying hardware to create a virtual computer. It abstracts physical hardware to provision resources like processors, storage, and network for the 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.
Hypervisor is categorized into two types:
Type-1 Hypervisor-This runs directly on the host machine’s physical hardware, so it’s also known as a bare-metal hypervisor.
Type-2 Hypervisor– runs on the operating system of the physical host machine, hence they are also called hosted hypervisors.
This article will explain in detail the advantages of each hypervisor, their usage, and the differences between them with examples so that businesses can choose one based on their requirement.
