A virtual machine (VM) is essentially one piece of software that contains operating systems, software, and files that take a portion of computing resources from your on-premises server. VMs behave like normal files, so you could deploy a fleet of them on any workstation with ease.
Unlike maintaining multiple servers, which have to be manually installed and configured, deploying virtual machines (VMs) require very little effort. By making a few simple adjustments in your virtualization console, you can easily create a virtual instance with enough resources to run even the most demanding apps.
