Virtualization in Cloud Computing: Definition, Types and How it Works

virtualization in cloud computing

Virtualization refers to the “creation (rather than an actual) version” of something such as a server or desktop, storage device, operating system, or network resource.

Also, Virtualization is a technique that allows you to share one physical instance of a resource or a shared application with multiple customers or organizations. It does this by assigning a name to physical storage when requested, it will provide a pointer to the physical resource.

What is the concept behind Virtualization?

Hardware virtualization is the process of creating a virtual machine that runs on existing hardware and operating systems. Virtual machines provide an environment that can be logically isolated from the underlying hardware.

The Host machine is the machine that the virtual machine will be created. The Guest machine is the name of the virtual machine.

Types of virtualization

  • Hardware virtualization
  • Operating system Virtualization
  • Server Virtualization
  • Storage Virtualization

1. Hardware Virtualization

Hardware virtualization is when the virtual machine software (or virtual machine manager ) is installed directly on the hardware system.

Hypervisor’s main task is to monitor and control the processor, memory, and other resources.

After the virtualization of the hardware system, We can install different operating systems on it and run other applications on them.


Because controlling virtual machines is easier than controlling physical servers, hardware virtualization is mostly used for server platforms.

2. Operating System Virtualization

Operating system virtualization is when the virtual machine software (or virtual machine manager ) is installed on the Host OS.


Virtualization of the Operating System is used primarily to test the applications on various platforms.

3. Server Virtualization

The virtual machine software or virtual manager (VMM)installs on the Host operating systems and not directly on the hardware also known as operating system virtualization.


Server virtualization can be done to allow a single physical server to be split into multiple servers according to demand and for load balancing.

4. Storage Virtualization

Storage virtualization is a method of grouping physical storage from multiple network storage devices to make it look like one storage device.

Software applications can also be used to implement storage virtualization.


Virtualization of storage is used mainly for backup and recovery.

How it works: virtualization in cloud computing?

Virtualization is an important part of cloud computing technology. Normally, cloud computing users share present in the clouds, such as applications, but t actually with the help of virtualization, they can also share the infrastructure.

Virtualization Technology’s main purpose is to provide applications with the current versions to their users. If the next version is released, the cloud provider must provide the most recent version to their users. This is because it is more costly.

This problem can be solved by using virtualization technology. Virtualization allows third-party people to maintain all the servers and software applications required by cloud providers. Cloud providers have to pay the money monthly or annually.


Virtualization is essentially the ability to run multiple operating systems on one machine while sharing all of the hardware resources. It helps us to provide the pool of IT resources so that We can share these IT resources to gain business benefits.
