![]() System VMs are widely used in most modern data centers, as they are easy to manage, make good use of existing IT infrastructure, and support core business needs like application provisioning, disaster recovery, and server consolidation. This allows a program to execute the same way no matter which platform is the host and provides a platform-independent programming environment. By contrast, a Process VM does not try to provide a full OS, but instead abstracts or masks all of the details of the underlying hardware and OS. A System VM is a substitute for a real machine, providing all the functionality that needed to run a full OS, and the hypervisor shares and manages the hardware and keeps all of the guests that are sharing the same machine isolated from each other. There are two distinct kinds of VMs: System VMs and Process VMs. A single host server can run several guest VMs at the same time using software called a hypervisor to manage them. This makes it ideal for testing beta software, backing up data for disaster recovery, accessing data that may be infected, and running different operation systems (OSes) on the same computer. It works like a computer within a computer, whose contents are safely sequestered from the rest of the system. It has its own window that is accessible to a user, and it can run its own applications and programs as if it were a free-standing machine. A VM is referred to as a guest of the computing environment where it is installed, which is known as the host. A virtual machine (VM) is a computer system emulation that behaves like a computer but does not need its own separate hardware in order to function.
