How Virtual Machine Works and its Benefits – Guide
A virtual machine (VM) is a virtual environment that functions like a computer within a computer. It runs on an isolated partition of your host computer with its own CPU power, memory, operating system (such as Windows, Linux, macOS) and other resources. End users can run applications on VMs and use them normally on their workstations. A virtual machine is a computer file, often called an image, that behaves like a real computer. It can run in a window as a separate computing environment, usually to run another operating system – or even function as the entire user’s computing experience – as is common with many people’s work computers.
How does a virtual machine work?
Virtualization is the process of creating a “virtual” version of a computer based on software, with dedicated amounts of CPU, memory and storage that are “borrowed” from a physical host computer – such as your personal computer – and/or a server. remote — such as a server in a cloud provider’s datacenter. A virtual machine is a computer file, commonly called an image, that behaves like a real computer.
It can run in a window as a separate computing environment, usually to run a different operating system — or even to function as the user’s entire computer experience — as is common with many people’s work computers. The virtual machine is partitioned from the rest of the system, which means that the software inside a VM cannot interfere with the host computer’s primary operating system.
What are VMs for?
Here are some ways virtual machines are used:
What are the benefits of using VMs?
While virtual machines function as individual computers with individual operating systems and applications, they have the advantage of remaining completely independent of each other and the physical host machine. Software called a hypervisor, or virtual machine manager, lets you run different operating systems on different virtual machines at the same time. This makes it possible to run Linux VMs, for example, on a Windows operating system, or to run a previous version of Windows on a more current Windows operating system.
And because the VMs are independent of each other, they are also extremely portable. You can move a VM on one hypervisor to another hypervisor on a completely different machine almost instantly.
Due to their flexibility and portability, virtual machines offer many benefits such as:
