What is Virtualization in Cloud Computing?

Listen in Audio

The term virtualization simply means the virtual representation of cloud computing servers.

To make it easy for you, there is virtual software that resembles the physical hardware resources to facilitate the process of cloud operations. The virtual emulation of operating systems, network resources, or servers is very helpful for several businesses.

Adding to it, cloud computing is one of the most effective methods to host multiple web-based applications. That is why hardware virtualization, operating system virtualization, server virtualization, and storage virtualization has become the talk of the town.

Now, most of you have thought about why this virtualization in cloud computing is creating a buzz. What are the types of virtualization in cloud computing, and the benefits of virtualization in cloud computing?

Here’s a guide for you that explains everything about virtualization in cloud computing.

Virtualization as a Concept of Cloud Computing

Virtualization in cloud computing makes the creation of virtual machines easier. By creating virtual machines, the smooth functioning of multiple operating systems is possible. Moreover, it is because of the virtual ecosystem for server operating systems and multiple storage devices that run across multiple operating systems.

Therefore, we say that cloud computing is identified as an application or service running in a virtual ecosystem. And thus, there will be less requirement for physical resources. In the modern industrial age, cloud computing and virtualization are increasing dramatically. With their growing demand, they will quickly be unified and will give higher ROI to businesses.

Both of these advancements work together and ensure that users get sophisticated computing levels to complete entire operations. Moreover, applications are easy to share on different network threads by just executing some commands.

Characteristics of Virtualization

The following are some of the features or characteristics of virtualization

End-users can create their own computing environment through the use of virtualization technology in cloud computing. In order to accomplish this, one host machine must be created. This host machine allows the end-user to limit the number of active users. It is easy to control by doing so. Power consumption can also be reduced by using them.
Access to server resources: Virtualization offers several unique features that eliminate the need of physical servers. With such features, uptime is boosted, and fault tolerance and resource availability are reduced.
Isolated virtual machines are provided by virtualization. It is possible to have many guest users on a virtual machine, and the guest users can be either operating systems, devices or applications.
Users get an isolated virtual environment by the virtual machine. At the same time, sensitive information is protected, and guest users remain interconnected.
As the virtualization system ensures continuous uptime, it does automatic load balancing and ensures that services are not disrupted.
Cluster management software is used to aggregate virtual machines in Virtualization. The software ensures that homogeneous sets of computers or networks are connected and work as one unified resource.

How Cloud Virtualization Works?

So far you have read a brief introduction about virtualization and its characteristics. Now, is it the time to understand how this virtualization principle works? After all, there are different advantages of virtualization in cloud computing. Basically, it is a complex level of cloud computing. These virtual machines are created and they are operated with the help of multiple operating systems on different storage devices.

Cloud virtualization allows hardware and virtual systems to function at the same time in compatibility with software tools. The delivery support is for IaaS solutions for cloud computing. To ensure the successful execution of applications, it provides networking, memory, and storage services.

It is also important to note that cloud virtualization enables businesses to run multiple cloud environments. Cloud storage platforms such as AWS S3, Azure Blob, File Storage, or private clouds can be pooled and managed from a single console. Businesses are able to operate optimally in the event of a disaster by preventing vendor lock-in.

How is server virtualization different from containerization?

With containerization, application code can be deployed to run on any physical or virtual environment without requiring changes. Developers bundle application code with libraries, configuration files, and other dependencies that make the code run. One package of software, called a container, can run on any platform independently. Application virtualization is a type of containerization.

It is similar to building a road to connect two places with server virtualization. Your application should run in a virtual environment created from scratch. Comparatively, containerization is like building a helicopter that can fly anywhere. You can run your application in any physical or virtual environment by using a container.

Key Cloud Security Benefits with Virtualization

You can leverage cloud computing in your business ecosystem with these advantages:

1. Flexibility

Users have a flexible sharing system without passing any physical resources among each other. So, the data is available across different systems.

2. Data Protection

With data virtualization in cloud computing, there is no room for data loss or malicious activities. It is because the information is stored in the virtual system.

3. Security against attacks

Methodically isolating applications and virtual machines reduce the risk of multiple attacks in case of exposure.

4. Cost Effectiveness

Virtualization reduces the amount of hardware needed in data centers, improving physical security in organizations.

5. Better Access Control

System and network administrators are granted a higher level of access control, which separates responsibilities and improves the system’s efficiency.

The Way Ahead

Organizations that aim to strengthen their cloud security can benefit from virtualization. In order to ensure a robust security posture, multi-layered protection must be implemented and adhered to systems. There is a need for organizations to develop strategies and have a better understanding of handling the security issues in virtual infrastructure and its components. Virtualization must be a top priority, not an afterthought, for organizations that look to strengthen their cloud security.
