How to Set Up and Manage Virtual Machines in Azure

A virtual machine is a software-based emulation of a physical computer that enables users to run multiple operating systems on a single physical machine. Virtual machines allow users to create isolated environments for testing software, running legacy applications, or running different operating systems on the same hardware. They are widely used in data centers, cloud computing environments, and software development. Virtual machines are created and managed using virtualization software such as VMware, VirtualBox, or Microsoft Hyper-V.
