What is virtualization technology in computing?

Well, virtualization is a form of partitioning hardware resources (hardware and/or memory) on a host operating system to allow users to access their data from another computer running the same operating system. Virtualization is an open source technology that empowers every desktop, laptop, tablet PC and smartphone to run any applications (programs) that they need from a remote location.

What is virtualization in computing

A brief history about virtualization technology

In the past most computers used one physical computer for processing tasks and serving data to other programs and devices. This setup was very limiting to both the consumer and the manufacturer of the computer. With the advent of the personal computer and the growth of cloud computing there has been a dramatic increase in what is available to consumers. There are now multiple computers that perform different tasks all performing at the same supreme level of speed. The virtualization in computing explanation refers to the act of dividing a physical computer system into multiple virtual systems so as to make use of the maximum amount of resources without having to dedicate the entire machine to perform tasks.

In previous years, there were two major methods of virtualization in computing, namely software virtualization and hardware virtualization. The latter is a lot more taxing on the operating system than the former, which is why it is not as commonly used.

Software Virtualization

Software virtualization means the utilization of a software virtualizer, which allows a program (virtualized) to “talk” to a specific device (physical) using generic code. In this way, one can think of a device like a mouse or keyboard and the virtualized application as a web browser. A similar method is used by the Hypervisor, which acts as a layer on top of the OS and is usually abstracted away from the OS in such a way as to allow a specific hardware virtualization environment to be created.

However, with the rapid development in technology, operating systems and virtualization have reached a new level of performance and complexity. Hardware virtualization is also advancing quickly, but it is not quite up to the same standard as software virtualization. To make a better understanding, let us take a look at a few key features of both virtualization and the current operating systems. This may shed some light on how one would go about choosing an OS for your computing needs.

Virtualization can be defined as the separation between the physical hardware and applications on a computer. This provides users with an environment that feels like a “dedicated” computer. In essence, users are given the impression that the computer is performing solely as it is expected to while running all activities in a completely isolated manner. By creating a virtual machine, this enables the user to run multiple virtual environments on one computer. This then allows users to have access to multiple programs at the same time on their virtual machine. Although, there are significant differences between the two, both still use shared resources on a computer to achieve their goals.

With that being said, virtualization is often seen on two main levels. On the highest level is known as OS-level virtualization where the operating system and its programs are completely hidden from any external processes. Although this option is not typically recommended, many companies do choose this because they do not wish to replace the operating system because they feel it is old. What is important is that the operating system and the programs are completely separate and a good example of this would be Microsoft operating systems which run on Hyper-v and virtual environments that run on VMWare ESX Server.

Platform level virtualization technology

Virtualization can also be found on a lower level, which is known as virtualization on the platform level. With this form, applications are run on a specific hardware device which then enables them to utilize the underlying virtualization technologies such as virtio, libvirt, etc. This allows an individual or a company to have their programs running on a hardware device which is not always something that is feasible. Therefore, they must find a method to run their applications without having to rely on a physical hardware device.

One of the most popular uses for virtualization in computing is when a company or an individual requires access to multiple operating systems, but they have only one physical server or workstation to run all of them. What this does is saves them money by using virtualization to run several operating systems on one server thus saving both memory space and monetary cost. What is important is that a person or company needs to determine what they want to achieve with virtualization before pursuing it. Then, they can easily find a company that will work with them to help them achieve their goals.
