The Power of Virtualization: An Introduction to Virtual Machines
A virtual machine (VM) is a software-based emulation of a physical computer. It is created and managed by a “hypervisor” and can run a complete operating system, behaving just like a real computer with its own CPU, memory, and storage. The key advantage of a virtual machine is that it allows multiple operating systems to run on a single physical machine, each isolated from the others. This technology is fundamental to cloud computing, server consolidation, and software development, as it offers a flexible, scalable, and cost-effective way to manage IT resources, test applications, and improve security by isolating different environments.
