Hypervisors in Cloud Computing

Comments 0 Comment

A hypervisor, also known as a virtual machine monitor (VMM), is a critical software layer in virtualization technology. It allows multiple virtual machines (VMs) to run on a single physical hardware system by managing and allocating resources such as CPU, memory, and storage to each VM. Hypervisors ensure that each VM operates independently, with isolated environments, while sharing the underlying hardware. Imagine you have a single powerful computer, and you want to run multiple operating systems like Windows, Linux, and…
