Virtual Machines

A virtual machine (VM) is a software-based representation of a physical computer that can run different operating systems and applications.

A virtual machine has its own CPU, memory, disks, and network interfaces, but it uses the resources of a physical host computer or server.

Virtual machines are isolated from each other and from the host, which means they are secure and portable.

Virtual machines are created and managed by a software layer called a hypervisor, which allows multiple virtual machines to run on the same physical machine.

Reasons for using a VM

Cost savings:

You can reduce the number of physical servers you need by running multiple virtual machines on each server. This saves on hardware, maintenance, and electricity costs.


You can easily create, delete, move, and resize virtual machines as needed. You can also run different operating systems and applications on the same physical machine, which can increase compatibility and productivity.


You can quickly add or remove virtual machines to match the demand of your workloads. You can also use cloud services to access virtual machines on demand, without having to invest in your own infrastructure.


You can isolate and protect your virtual machines from malicious attacks or unauthorized access. You can also backup and restore your virtual machines easily, in case of any failure or disaster.
