Computer Network with serverVirtualization  is a type of technology that has been around for a few years now, however has only recently started to make its way into the everyday vocabulary of those who are involved in the IT industry. This technology itself helps in radically transforming a company’s infrastructure and improves overall efficiency of the company.

What is a Virtualization?

Many people tend to confuse virtualization technology with other form of technologies and sometimes also confuse in differentiating between virtualization and cloud computing. In Computing, Virtualization technology refers to the act of making a virtual version of something, such as network components, storage devices, computing environments or operating systems rather than utilizing a physical version for particular aspects of a company’s infrastructure.

For instance, server virtualization is the process in which many operating system applications operates on the same server simultaneously, as opposed to one server running one OS. This offers a company the capability to use their resources effectively and lowers the total costs that come with maintaining servers.

Types of Virtualization Technology

This technology can be used in several ways and can also take multiple forms aside from just server virtualization. The major types include hardware, application, desktop, storage and user.

  • Application virtualization

This server enables the user to access the application, not only from their workstation, but also from a remotely located server. This server stores all personal information and characteristics of the application, however can still operate on a local workstation.

  • Desktop virtualization

It is a special server technology that separates the associated application software and desktop environment from the physical client device which is used to access it. Desktop virtualization can be utilized in conjunction with the user profile management systems and application virtualization for providing a comprehensive desktop environment management system. All the components of the desktop, in this mode are virtualized. This results in a highly flexible and more secure desktop delivery model. Moreover, this approach also supports a more complete desktop disaster recovery strategy because all the components are saved in the data center. If a user’s hardware is lost, the restore is much easier and straightforward since all the components will be available at login from another device.

  • User virtualization

This server is much similar to desktop virtualization, but allows all users to maintain a completely personalized virtual desktop when not on the company network. All users can log into the desktop from various types of devices, such as tablets and smartphones. Since more companies are migrating to a BYOD policy, user and desktop virtualization are becoming increasingly popular.

  • Storage virtualization

It is the process of combining physical storage from many network storage devices. In this way it acts as it is on one storage device.

  • Hardware virtualization

This form of virtualization uses one processor to act as several different processors. Users can then run multiple operating systems on the same hardware. This form of virtualization needs a VM (virtual machine manager) known as a hypervisor.

  • Server Virtualization

The partition of physical servers into smaller virtual servers for maximizing your server resources is known as server virtualization. All the resources of the server are hidden, from users, and software is used for dividing the physical server into several virtual environments, known as private or virtual servers.

Benefits of Virtualization

Virtualization technology consolidates and organizes computer resources. Since both existing IT resources and equipment are leveraged, virtualization proves to be a cost-effective IT solution. Virtualization minimizes maintenance costs, licensing costs and, without a server room for maintaining, utility costs.

This technology has helped in reducing data centre space and power consumption. It helps in increasing hardware utilization, lower upfront and operational costs, for both training and maintenance. It also simplifies desktop and application lifecycle management, helps in leveraging your Windows Server skills, utilizing already purchased Windows Server capabilities, improving service levels, minimizing disruption to services, enhancing desktop business continuity, reducing user and application data deployment time and providing access to applications regardless of the location

1. Benefits for Companies

The major advantages of virtualization for a company are as follows

  • Greater company agility and efficiency
  • Virtualization also helps in increasing productivity, since employees can access the company network from any place.
  • Since Data is stored on one centralized server, this results in lowering risks of stolen or lost data.

2. Benefits for Data Centers

Not only it is beneficial for companies, but virtualization technology also provides many benefits for data centers. For instance, it cuts costs and wastes associated with cooling and maintaining its servers by maximizing the capabilities of a single server. It also allows a data center to be smaller in size, which results in overall savings due to a reduction in money and time required for maintenance, energy needed and hardware used.
