Virtualization in Cloud Computing: Types, Advantages, and Features

Virtualization is a mechanism for decoupling a service from its underlying physical delivery. It is the process of generating a virtual representation of something, such as computer hardware. It was first created during the mainframe era. It entails using specialized software to generate a virtual or software-generated version of a computing resource rather than the basic version of the same help. Multiple operating systems and applications can run on the same machine and its same hardware at the same time, thanks to Virtualization, enhancing hardware usage and flexibility.

According to research, In cloud computing, virtualization refers to the creation of a virtual platform comprising server operating systems and storage devices.

What is Virtualization?

Virtualization is a process that allows you to create a virtual version of a desktop, operating system, network resources, or server. Virtualization is critical and prominent in cloud computing.

This separates the physical delivery of the resource or application from the actual help itself. It aids in reducing the amount of space or cost associated with the resource. This method allows the end user to run numerous desktop operating systems and apps simultaneously on the same hardware and software.

The procedure also ensures the virtual emulation of products or services in the same machine while not slowing down or interfering with the system’s efficiency.

Virtualization was invented during the era of mainframe usage and as time progressed with advancements in new-age technology.


Virtualization as a Cloud Computing Concept

Virtualization in cloud computing simplifies the development of virtual computers and ensures the smooth operation of numerous operating systems. It also contributes to creating a virtual ecosystem for server operating systems and multiple storage devices and running several operating systems.

Cloud computing is defined as a virtual ecosystem-based application or service. An ecosystem of this type could be public or private. Virtualization decreases the need for physical infrastructure. Cloud computing and Virtualization are usually used interchangeably and are gradually becoming united.

Scalability, efficiency, and economic value are all advantages of cloud computing. It provides simplified workload management systems.

Cloud Computing, in conjunction with Virtualization, provides the modern organization with a more cost-effective solution to operate several operating systems on a single devoted resource.

Features of Virtualization in cloud computing

  • Resource distribution: 

Virtualization and Cloud Computing technology enable end users to create their computing environment. It is accomplished by establishing a single host machine. The end-user can limit the number of active users using this host computer. As a result, it makes control more accessible. They can also be utilized to reduce energy consumption.

  • Access to server resources: 

Virtualization provides various distinct advantages that eliminate the requirement for physical servers. Such characteristics increase uptime while decreasing fault tolerance and resource availability.

  • Isolated Virtual Machines: 

Virtualization enables isolated virtual machines. Each virtual machine can have several guest users who can be operating systems, devices, or programmes. The virtual machine separates such guest users in a virtual environment. This ensures that sensitive information is kept secure while keeping guest users connected.

  • Security and authenticity: 

Virtualization technologies offer continuous system availability, automatic load balancing and fewer service disturbances.

  • Aggregation in Virtualization: 

It is accomplished by cluster management software. This programme guarantees that disparate groups of computers or networks are linked and function as a single unified resource.


The Virtualization Architecture

Virtualization architecture is defined as a model that conceptually describes Virtualization. The application of Virtualization in cloud computing is crucial. End-users share data on apps known as clouds in cloud computing. On the other hand, end users can share the entire IT infrastructure via Virtualization.

Virtual infrastructure and application services help manage infrastructure and applications, respectively.

Virtual data centres and operating systems embed both services. Virtual services work on all platforms and languages. On-premise or off-premise clouds provide services. Third parties offer cloud virtualization services. Cloud users pay third parties monthly or annually. This fee compensates third parties for cloud services and application versions ordered by end-users.

The hypervisor is typically used to achieve Virtualization. A hypervisor separates operating systems from the underlying hardware. It allows the host machine to perform many virtual machines simultaneously while sharing the same physical computer resources. There are two approaches for achieving virtualization architecture, which are detailed below:

  • Type one: 

The earliest type of hypervisor is known as a bare-metal hypervisor. They run directly on top of the host system’s hardware. They provide good resource management and ensure that resources are always available. It gives you direct access to the hardware system, which improves scalability, performance, and stability.

  • Type two:

The hosted hypervisor is the second type of hypervisor. The virtual operating system runs directly beyond the hypervisor and is installed on the host operating system. It is the type of system that makes system configuration easier and simpler.

It also makes managerial chores easier. The host operating system’s presence might limit the virtualized system’s performance and create security issues or dangers.

Types of Virtualization in cloud computing

Virtualization technology has numerous varieties or kinds, which are listed below:

  • Desktop Virtualization

This type of Virtualization allows end-user operating systems to be remotely stored on a server or data centre. It enables users to access their PCs while sitting in any geographical location remotely. They can also access their computers virtually by using separate machines.

With desktop virtualization, end-user can operate on many operating systems based on their business requirements.

If the person wants to work on an operating system other than Windows, he can employ desktop virtualization. This allows the individual to work on two separate operating systems.

  • Application Virtualization

This is the form of Virtualization that allows an application’s end-user to have remote access.

This is accomplished through the use of a server. This server contains all the personal information and other characteristics required to use the programme.

The server is available through the internet and runs on a local workstation. An end user can execute two versions of the same programme or application using Virtualization.

Application virtualization is available as packaged software or as a hosted application.

  • Storage Virtualization

This sort of Virtualization offers virtual storage solutions that make storage management more effortless.

It enables effective storage management by allowing access to numerous sources from a single repository. Storage virtualization ensures smooth and constant performance.

It also provides ongoing upgrades and patches for advanced functions. It also aids in dealing with changes in the underlying storage device.

  • Network Virtualization

This type of Virtualization can run many virtual networks, each with its control and data plan. It occurs on top of a physical network and can be operated by people unaware of one another.

Network virtualization develops virtual networks and keeps a supply of virtual networks on hand.

Logical switches, firewalls,work load security routers, load balancers, and workload security management systems can all be developed using network virtualization.

  • Data Virtualization

This Virtualization is where data is sourced and collected from multiple sources and controlled from a single location. There needs to be a technical understanding of where such information is sourced, gathered, kept, or formatted.

The data is logically organized, and interested parties and stakeholders can then access the virtual view of such data. These reports can also be viewed remotely by end users.

Data virtualization applications range from data integration to business integration. They are also used for data services in service-oriented architecture and to help identify organizational data.

  • Server Virtualization

This type of Virtualization ensures server masking. The primary or intended server is partitioned into numerous virtual servers. To help the masking procedure, such servers continually change their identity numbers and processors. This make sure that each server can run its operating system entirely independently.
