I understand that in a work environment, different types of servers doing specific tasks can be each a VM.
In: Engineering
Well, a VM is a just an operating system running under other operating system. In a work environment is useful because you can isolate the access and limit the resources that each VM can uses in order to improve security, optimize resources and because they are easier to manage(you can create, remove,start or stop virtual machines through software so you don’t need physical access to the computer).
For home users is most useful when you want different operating systems(like if your main OS is Linux but you need to run a Windows application), but you don’t want to install the other operating system instead of your current system or to install it beside it, which can be tricky. Also you benefit from the features mentioned for the work environment, most important the easy management and security, for example executing a risky application.
