Understanding the Types of Virtualization in Cloud Computing

Virtualization in cloud computing refers to creating virtual versions of computing resources, including servers, storage, and networks, to run multiple virtual instances on a single physical infrastructure.

Thanks to this emerging technology, businesses can now efficiently utilize resources and enhance flexibility & scalability to build, deploy, and manage software apps in the cloud. All right! This article will discuss different types of virtualization in cloud computing. 

Virtualization enables efficient resource utilization, scalability, and flexibility in deploying and managing software applications in the cloud. Virtualization is a cloud computing component that allows you to optimize hardware usage and improve the performance and cost-effectiveness of cloud services. It has completely transformed the way we used to manage computing resources. 

But what is virtualization in cloud computing, and what are the different types in cloud computing? Whether you’re a business or an individual professional wondering about the various types of virtualization in cloud computing, continue reading this article.

What is Virtualization in Cloud Computing?

Virtualization is a computing technology that involves creating a virtual version of physical resources like a server, storage device, network, or a complete operating system. It is a primary component of cloud computing, which allows users to access computing resources such as servers, storage, and applications on demand via the Internet.

With virtualization, businesses can run multiple virtual instances on a single physical infrastructure, significantly reducing hardware complexity and improving resource utilization.

Virtualization is the backbone of cloud computing, which helps deliver various cloud services to businesses. Cloud applications are needed for multiple reasons, as they provide more flexibility, scalability, and reliability. Using cloud computing, cloud providers can now effectively manage and allocate resources, ensuring that users can access computing power without having to rely on particular hardware.

What are the Different Types of Virtualization in Cloud Computing?

There are different types of virtualization, which are mentioned below:

1. Desktop Virtualization

Desktop Virtualization allows you to run multiple operating systems with their virtual machines running on the same system. There are two main types of desktop virtualization: virtual desktop infrastructure and local desktop virtualization. Let’s understand them in detail:

a) Virtual desktop infrastructure 

This type of desktop virtualization can run multiple virtual machines on a central server and then host it to the host system to meet the on-demand users’ needs. It allows you to access the operating system from anywhere and on any device without installing the actual operating system on your local machine.

b) Local desktop virtualization

Local desktop virtualization allows users to run multiple operating systems simultaneously on their local computers without affecting the host machine.

2. Network Virtualization

Network virtualization involves creating a virtual instance of the network, which is primarily managed from a single console. As a result, it helps businesses simplify network management by abstracting away hardware components (e.g., switches and routers). 

Software-defined networking (SDN) and network virtualization are the two types of network virtualization mentioned below:  

a) Software-defined networking (SDN)

It allows users to virtualize hardware that can be used to control network traffic routing.

b) Network function virtualization (NFV)

This network virtualization is used to virtualize hardware appliances offering network-specific functions for seamless configuration and management, including firewall security.

3. Storage Virtualization

Storage Virtualization allows you to access all the storage devices for the system and manage them as a single pool. With storage virtualization, you can gather all the storage into a single pool, allowing it to allocate it to any virtual machines on the network as required.

Furthermore, we assist the hypervisor in assigning storage to virtual machines as efficiently as possible without wasting any hardware resources.

4. Application Virtualization

Application virtualization is the method of virtualizing applications in cloud computing, one of the ways users can access applications remotely. Servers contain all data and information related to applications running on them, but they can also be accessed over the Internet by systems in other geographic areas. There are three types of Application Virtualization: 

• Local application virtualization often runs on the host device in a virtual environment, not on the hardware.
• In application virtualization, the app runs on the server side and can send some components to the host device when needed.
• Using server-based application virtualization, the client system has a single interface, and no client-side processing is involved.

5. Cloud virtualization

Virtualization technologies provide the foundation for the three main service models in cloud computing. Cloud virtualization is the process of virtualizing cloud servers, storage, data, and other parts of the hardware resources to a greater extent. There are mainly three types of cloud virtualization, including:

a) Infrastructure-as-a-service (IaaS)

IaaS provides virtualized computing resources like virtual machines, storage, and networks. Microsoft Azure Virtual Machines and Amazon Web Services (AWS) EC2 are some examples of IaaS. 

b) Platform-as-a-service (PaaS)

PaaS is a leading cloud computing platform that allows users to develop and manage applications without worrying about the underlying infrastructure management. With virtualization, applications are isolated from one another and run smoothly on the same computer. Google App Engine is a good example of a PaaS cloud platform. 

c) Software-as-a-service (SaaS)

SaaS delivers software over the internet on a subscription basis. Virtualization allows you to seamlessly update and maintain software while ensuring immersive user experiences across all devices and platforms. Microsoft 365 and Google Workspace are examples of SaaS.

6. Data virtualization

Data virtualization involves abstracting data from multiple sources (databases, data warehouses, cloud storage, etc.) into a virtual data layer. In this layer, data from a wide variety of sources is presented to users and applications in a consistent format, providing a unified view of information. 

Additionally, it is used in applications for retrieving and manipulating data without requiring technical information. There are several reasons why data virtualization is a better option than storing data directly on individual hard drives.

Importance of Virtualization in Cloud Computing

There are numerous benefits of virtualization, including but not limited to: 

a) Improved Flexibility & Scalability

With virtualization, users can abstract physical hardware functionality into software and seamlessly interact with hardware resources without hassle. Thanks to virtualization, it is now possible to increase system workloads with existing hardware resources. 

b) Enhanced data analysis and server reliability

Thanks to virtualization, you can easily optimize hardware, software, and storage while seamlessly analyzing and managing large volumes of data. Virtualization also enhances the reliability, scalability, and availability of computing resources, such as servers. 

c) Cost-Effectiveness

Virtualization allows businesses to consolidate multiple physical servers onto one virtual server, reducing overall infrastructure costs.  

d) Improved software development

Virtualization allows developers to run software without causing any impact on other applications. 

e) Centralized management

Virtualization enables seamless centralized management of desktops.

Conclusion

In conclusion, it’s clear that there are different types of virtualization, each with its own properties and serving various purposes in cloud computing. Virtualization in cloud computing is a huge plus, which allows businesses to better utilize their computing resources and improve their flexibility and scalability.
