Requirement and Purpose of Virtualization in Cloud Computing

BlogsCloudTechRequirement and Purpose of Virtualization in Cloud Computing

The Purpose of Virtualization in cloud computing aims to bring many critical benefits to organizations. Virtualization is the foundation of cloud computing. It brings essential benefits such as creating multiple simulated environments within single IT hardware, creating a virtual barrier, saving time and money, etc. As we all know, the cost of hardware is expensive. Hence, with Virtualization, an organization can create many virtual instances with a single piece of hardware.

Virtualization computing helps organizations lower their inventory cost by creating virtual resources like servers, desktops, files, storage and network, operating systems, etc. Virtualization has become an integral part of IT industries as today it is applied to a wide range of system layers. But, the system layers include OS-level Virtualization, hardware-level Virtualization, server virtualization, etc. Here in this article, we will study the purpose of Virtualization.

What do you mean by Virtualization?

Virtualization creates virtual machines (VMs) on a virtual computer system using the software. It creates an abstraction layer over the hardware. With the help of virtual machines, organizations can allow running multiple virtual computers, OS, and applications on a single server. It divides single servers into several virtual servers. One of the main advantages of Virtualization is that it’s more efficient than any other computing technique.

Virtual machines represent the computer, and Virtualization allows organizations to create VMs with their OS and applications on a single hardware. As a result, virtual machines need software called Hypervisor to interact with physical hardware. However, it cannot directly connect to the physical hardware. In the same vein, the Hypervisor is very important for Virtualization as it allows some operating systems to work or run. Moreover, it is a thin software that is required for the virtualization process.

There are four fundamental properties of virtual machines:


  • Firstly, Virtual machines help to run multiple OS on a single hardware.
  • Secondly, it divides system components into numerous virtual machines.


  • VMs deliver fault and security isolation at the hardware level.
  • With advanced resource controls, preserve performance.


  • Moving and copying virtual machines is become easy.
  • It helps to save complete Virtual machines data to files.

Hardware Independence

  • Most importantly, it can provision or migrate any virtual machine to any physical server.

How does Virtualization work?

Businesses are growing day by day, and there is a need to deploy multiple servers to work efficiently. Most organizations cannot deploy x86 servers due to some limitations. But due to some limitations of x86 servers, many organizations cannot do so. Hence, Virtualization in cloud computing makes their work easy. However, virtualization is dependent on software called Hypervisor, which is needed to create virtual computer systems. With Virtualization, organizations can run multiple OS, Virtual Systems, and many applications.

In other words, virtual machined is termed a Virtual Computer System. It is a software container with an OS and application present inside. Every virtual machine is independent. Further, creating multiple virtual machines on one computer hardware enables many operating systems and applications to run on a single server.

The host is the initial hardware parameter that operates the virtual Machine (VM), and the guest is nothing but a VM operating harmony in the host. Virtualization can use many OS to single central control and not reserved for one computer. Therefore, it will help for more extensive networks with multiple systems.

Purpose of Virtualization

The primary purpose of Virtualization is to run multiple applications normally. Virtual machines can allow server administrators to contract and expand servers without adjusting hardware. Moreover, with Virtualization, we can increase efficiency by dividing a single system into multiple parts.

Virtualization also helps to isolate each system without damaging any parts of it. If anything wrong happens with the operating system, Virtual machines use Hypervisor to protect the autonomy of all virtual guests being rubbed on a single host.
Operating System-level Virtualization is the most common form of Virtualization. At this level, we can run multiple OS on a single hardware. The virtualization process includes the separation of hardware and software. Further, iT will take place by emulating hardware using the software.

Above all, a virtual machine (VM) is a data file that can move or copy from one computer to another, just like the standard file. Similarly, categories of virtualizations are desktop, file, storage, etc. Now Virtualization has become an integral part of the computing process, as it has multiple benefits for an IT organization.

What are the main benefits of Virtualization?

There are many benefits of Virtualization offers with maximizing their output. Some additional benefits are as follows:

Single-minded servers

Virtualization delivers an easy and cost-effective way that helps organizations separate their databases, emails, and web servers.

Expedited deployment and redeployment

In an organization, if the physical server gets crashed, the availability of extra backup is not always there. Also in such cases, the clone of the server image is not always available. The redeployment process is very time-consuming and laborious. Therefore, if the data center is virtualized, then this process is easy and will be done in a short period.

Slash your IT expenses

If you are working in a non-virtualized environment, it can be inefficient. Because when you are not consuming the application on the server, the computing is idle and can not be used for other applications. A single physical server can transform into multiple virtual machines (VM) with Virtualization. Further, VM having different OS can run various applications, all hosted on a single server.

Increase efficiency and productivity

Virtualization helps the organization of greater efficiency and productivity. With fewer servers, the IT team will need less time for hardware maintenance which automatically saves operating time. Therefore, fewer time requirements are helping the IT environment to increase productivity.

Control independence and DevOps

Because of Virtualization, your IT developers can quickly spin up a VM without impacting a productive IT environment. Moreover, with a virtualized environment, developers can easily clone virtual machines. Also, testers can test the background without any difficulty.

Types of virtualizations

Virtualization can utilize in different ways to revolutionize your business. Here are some virtualization types that can help your business.

Server virtualization

Server Virtualization enables businesses to run multiple operating systems on a single server with high efficiency on Virtual Machines. Moreover, these wholly independent virtual server helps to reduce operating costs, eliminate sprawl, and deliver higher server availability.

Application virtualization

The organization can directly deliver to end users’ devices from a straight server with application virtualization. However, if your network server has some log, your employees can also access the application.

Network virtualization

Network virtualization can completely change the structure of the physical network. It combines all networking parameters into a single, software-based resource. Hence, this will allow them to work on a virtual network as they would work on the physical network.

Desktop virtualization

Desktop virtualization is one of the most popular types of Virtualization. It separates the desktop environment from the hardware and allows users to access their files and data from any PC. However, with desktop Virtualization, your employees will no longer need to come to the office to do a specific task; they can access their files anywhere.


In conclusion, the purpose of Virtualization is to make the IT environment more effective and productive. There are many benefits of Virtualization, starting from agility to increasing your workspace’s performance. Segmenting single physical hardware into virtual machines helps businesses make the most of available hardware. It will lower the cost and improve efficiency.
