What is Virtualization

What is Virtualization is a procedure in modern technology that facilitates users to develop valuable IT actions using resources traditionally associated with hardware. It enables you to utilize the entire capability of a physical device by allocating its potential among many users or environments. 

It is the way toward making software or a virtual portrayal of something, like virtual applications, storage, networks, and servers. Virtualization is the best method to cut IT costs while improving effectiveness and skillfulness for organizations of any size.

Example of Virtualization

In other words, it’s is the most revolutionary technology that permits the development of ‘virtual’ computers that operate on an actual computer. In this way, you can produce numerous virtual computers on the physically usable computer, in this manner permitting you to run various kinds of virtual computers of different operating systems such as Windows XP, Windows 7, Linux, Mac, etc. all on the one actual computer. The physically available computer should not be at your home or your work – it very well may be running on a PC that may be working on another continent. But it would perform in the same manner as an actual computer. 

History of Virtualization 

When it comes to the history of Virtualization, there are many theories given concerning its history but the most acceptable one dates back to the 1960s and was launched by organisations like General Electric (GE), Bell Labs, and International Business Machines (IBM).

How does Virtualization work?

Virtualization is not a rocket science technology that is hard to understand but a process of the latest technology where application, guest operating system (guest OS) or data storage is pulled away from the actual substantive hardware or software. A pivotal practice of virtualization technology is server virtualization, where a software layer works which is known as a hypervisor. Its work is to mimic the underlying hardware. Normally this procedure is to incorporate the CPU’s memory, input or output and web traffic.

Hypervisors obtain the physical resources and distinguish them so they can be operated by the virtual environment. They are equipped to settle on top of an operating system or in some other cases, they can be straightly launched onto the hardware. Hypervisors receive available physical resources and split them up so that virtual environments can utilize them.

Resources are divided depending on the condition from the physical environment to the numerous virtual environments. All the users associate with and run calculations inside the virtual environment. The virtual machine works as a single data document. What’s more, similar digital documents tend to be moved which are starting with one PC then onto the next, can be open to any one of the computers and works the same.

1.The virtualization procedure starts with the separation of the physical resource from their physical environment using the Hypervisors.

2.Resources are divided and distributed as per the requirements, starting with the physical environment to the numerous virtual environments.

3. System users work within the virtual environment and perform calculations in it.

4.When the virtual environment is running, a subject or program can send guidance that requires additional resources from the physical environment. Accordingly, the hypervisor transfers the message to the actual system and stores the modifications. This interaction will occur at a practically normal speed.

What are the types of Virtualization?

Data Virtualization 

Data that is circulated everywhere can be unified into one entity source. virtualization enables corporations to deal with data as a continuous supply—giving operating skills that can be used to consolidate data from many sources, effortlessly take in fresh data sources, and convert the data as per the requirements of users. virtualization mechanisms stand in front of many data streams and entitle them to be dealt with as one unique source, providing the necessary data in the demanding. 

Examples- TIBCO Data Virtualization, Oracle Data Service Integrator, Denodo, Actifio Sky, Red Hat JBoss Data Virtualization, AtScale, Stone Bond Enterprise Enabler

Desktop Virtualization

Desktop virtualization is a modern-day technology that enables the storage and formation of various user desktops on one main host which is mainly located in a database centre that may be far away. It is a part of virtualisation which permits you to apply several operating systems on a single machine. It enables the main administrator or in some cases a self-regulating administration device to launch imitated desktop environments to numerous physical devices at a time located in any place. Not like other conventional desktop environments which are installed physically, checked, configured, updated and remodelled on every machine. Desktop virtualization provides the central administrator to conduct mass setups, updates, and safety inspections on every virtual computer all in one time.

Examples- VMware Horizon View, Citrix XenDesktop

Server Virtualization 

Server virtualization is a method of separating the resources of one server into a considerable number of virtual servers according to the needs. All the virtual servers can operate as different devices. Server virtualization authorizes corporations to operate different numbers of autonomous operating systems all with different compositions requiring only an individual server. This procedure also helps in conserving the hardware expense included in maintaining a physical server. In this way, companies can formulate their server infrastructure more simplified.

Examples- Citrix XenServer, Microsoft’s Hyper-V, Red Hat’s Enterprise Virtualization

Network Virtualization

Network virtualization assists in controlling and regulating the whole computer network as one administrative element. Users can maintain a list of many characteristics of network infrastructure like switches and routers based on a single software console. Network virtualization enables web optimization for transferring data, speed, flexibility, safety, dependability, and availability. It enhances the all-around network’s progress and capacity. It comes to be manageable for administrators to distribute and administer resources effectively and assure increased and lasting network execution.

Examples- VPN, LAN  Routing, VLAN, NIC Switch

Storage Virtualization

Storage virtualization can be defined as a bunch of accessible storage devices which can be completely managed from a main or primary single device. With Storage Virtualization, the details, data and information saves in various locations and are protected with utmost safety and precautions so that if any harm to data can take place, it can be easily recovered. The main output of storage virtualization is fusing physical storage of many network storage tools so it works as a sole storage device. Storage virtualization provides many services such as simple backup, archive and recovery of files etc. It supports administrators in distributing, action, modification and arranging the resources effectively.

Examples- LUN’s (Logical unit number), Logical volume (LV), RAID groups

Application Virtualization 

Application Virtualization is the simple method of introducing or installing an application on the main server, in other words, on a one computer system that can easily be administered on numerous systems virtually is known as application virtualization. For the users sitting far away, the virtualized application functions just like an aboriginal application that is installed on an actual computer. With the help of application virtualization, it becomes simpler for companies to remodel, update, maintain, and check applications on a single system. It also helps users to get in touch with virtualized applications on devices that are non-Windows like iOS or Android. 

Examples- Citrix XenApp, Novell ZENworks Application Virtualization, VMware ThinApp

Benefits of Virtualization

Using the most significant technology of the modern world in increasing dependability on computers, Virtualization can boost IT skill, capability and flexibility and at the same time develop substantial pocket savings. It helps in the workload movement, improved execution and presence of all the necessary resources, automatic procedures etc.
