Hypervisors, also known as Virtual Machine Monitors (VMMs), allow multiple operating systems to run on a single hardware platform, maximizing hardware utilization and enabling isolated virtual environments. Hypervisors fall into two categories—Type 1 and Type 2—each serving different use cases, with distinct performance characteristics, benefits, and costs. Understanding these differences can help IT professionals and businesses select the best hypervisor for their needs. What is a Hypervisor? A hypervisor enables virtualization, a technology that allows multiple virtual machines (VMs) to run on a single physical machine, sharing its resources such...
