The Importance of Virtualization

Virtualization is an important, popular and very useful technology that enables the creation of useful IT services, by building virtual versions of computer hardware platforms, software-based resources, computer network resources, storage devices, applications etc. Virtualization creates multiple simulated environments or dedicated resources from a single hardware. It functions with the aid of software that makes it possible to install multiple operating systems. In this technology a physical machine’s full capacity is utilized by apportioning its capabilities among multiple users as well as environments. Virtualization can be of many types. Its major types are network virtualization, storage virtualization, application virtualization, desktop virtualization and server virtualization.

Virtualization technology works with the aid of hypervisors, which are a type of software. A hypervisor is used to separate the physical resources from their virtual environments. Hypervisors can be installed on hardware, such as a server, or these can exist atop an operating system. A hypervisor divides physical resources, so that these can be used by virtual environments. Resources are segregated, based on requirement, for the creation of multiple virtual environments. Users interact with these virtual environments and carry out their computations within it. This virtual environment is referred to as a Virtual Machine (VM) or a guest machine. A VM acts as a single data file and is capable of being moved from one computer to another without losing its functionality.

While a virtual environment is operational and an instruction is issued by a user or a program requiring the physical environment’s additional resources, it is the hypervisor that relays this request to the system as well as caches the changes. This takes place at speed which is close to the native speed.

The extensive use of virtualization is due to its major benefits. It provides an effective solution to organizations for partitioning their servers and running legacy apps on a number of OS (Operating system) types and versions. It results in servers being used more efficiently, which leads to an overall cost reduction for the company that is using this technology, especially with regard to buying, setting up and maintaining servers. Moreover, the applicability of virtualization has aided in curtailing vendor lock-in. Virtualization is being used widely by enterprises due to the advantages that it has to offer. Many businesses have started using specialized software for virtualization management, which emphasizes the essential role that this technology is playing in the seamless functioning of today’s businesses that rely heavily on IT resources.
