The Two Types of Virtual Machines

VMware backup software is specially designed for a specific type of software implementation of a machine called a virtual machine. Virtual machines are used to perform mirrored instructions of a physical machine. They have been praised in software news magazines for their ability to save information and protect data..

The term “virtual” originated came from the study of mirrors, called optics. Objects that appear in mirrors are really just reflections of their physical counterparts, but they look exactly the same.

Virtual machines are separated into two types of categories based upon their job and degree of connection with a real physical machine. One of these types is called a system virtual machine and the other type is known as a process virtual machine.

A system virtual machine provides an entire system platform to its users. A systems platform is a type of hardware blueprint software framework that allows software to run. The system virtual machine helps to sustain an entire operating system. It allows physical machines to run data to multiple virtual machines. Each of these machines runs on its own separate operating system. The software providing the virtualization is called the hypervisor and can run on top of an operating system.

There are many advantages to system virtual machines. They can co=exist on the same computer and work efficiently together. It can also provide an instruction set that is somewhat different from the physical machines. It is easy to maintain easily transported. The disadvantages include an inefficiency when accessing the hardware directly and instability when running off of the same physical machine host.

A process virtual machine is also referred to as an application virtual machine. These virtual machines support a single process and run as a normal application. It provides a platform-free programming environment that allows a program to execute in the same way on any platform.

This type of virtual machine provides a high level abstraction and has become extremely popular with Java programming language and the Parrot virtual machine.

A special kind of process virtual machine is one with systems that can abstract over communication devises of computer clusters. These process virtual machines have one process per physical machine in the cluster instead of a single process. They are created to make the job of programming parallel applications easier.

Using virtual machines and the VMware backup solutions that accompany them is a very smart investment. It will protect your data and secure your computers.
