Virtualization in Cloud Computing

Virtualization in Cloud Computing

Virtualization in cloud computing is a technology that allows a physical instance of a server or sharing resources between multiple users or multiple organizations, in other words, it is essentially a platform to create a server operating system (operating system). Storage devices, desktops, or network resources. When we talk about cloud virtualization, virtualization occurs using the resources available in the cloud to make cloud virtualization possible, which is shared among users.

How Virtualization Works in Cloud Computing

There can be many ways to run multiple applications and multiple users using a single server and one of these techniques is to implement software to create virtual machines to move from one host to another and create them. Never allow interruptions during your work. This method is also known as live transfer. Another approach involves load balancing techniques where the load is balanced across multiple hosts to make better use of virtual machine resources. This method is also known as dynamic resource handling.

When we talk about cloud computing, it's not just about sharing user data but also about sharing their infrastructure to create virtualization techniques that almost any organization I can be useful. It is then used to provide users with standard versions of the application for cloud computing. Once the latest version is released, it can be effectively delivered to the cloud and users.

Here are two ways to enable virtualization in the cloud.

• Operating System Virtualization - In this cloud computing virtualization, any application can run multiple times in any operating system.
• Hyperiser-based virtualization - In this process, the operating system shares the hardware from the host computer and, therefore, allows multiple operating systems (operating systems) to run on the same host.
• Grid view - Here, a given workload is distributed across multiple physical servers and once the result is calculated, it is returned. This type of service is mainly used for scientific purposes.

Types of Virtualization in Cloud Computing

Some of the important types are mentioned below.

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

1. Hardware virtualization

In Hardware Virtualization, Virtual Machine Manager, ie VMM, is located and installed on the hardware system. VMM installs software into the hardware system and hardware virtualization is enabled. Hyperizer is mainly used here to monitor and control memory, processor and other hardware resources.

Once the hardware virtualization is activated, you can install a different operating system (operating system) on it and run many applications on the installed operating systems.

2. Virtualization of the operating system

In operating system virtualization, VMM (virtual machine manager) or virtual machine software is installed in a host's operating system (OS) instead of hardware. Operating system virtualization is mainly used to test applications on different operating systems, ie on a different OS platform.

3. Server virtualization

In server virtualization, VMM (Virtual Machine Manager) or virtual machine software is installed directly on the server system where load balancing can be divided into multiple servers depending on the resource usage. This is done to meet the demand for resources and the server administrator plays the role of dividing the physical server into multiple servers.

4. Storage virtualization

In storage virtualization, physical storage is bundled from different servers (from different devices / network locations). When finished, it looks like a storage device. These all run through a virtual storage system. It can also be implemented using software applications. Storage virtualization servers in cloud computing do not know where the data is stored. The primary use of storage virtualization is to provide backup and recovery processes.

Benefits of virtualization in cloud computing

• Security - Security in virtualization is provided using firewalls and encryption. This ensures that everything in the virtualization cloud is protected and unauthorized access can be prevented. Data can also be protected from cyber attacks and threats related to files such as malware, worms and viruses.
• More economical - as we have seen, virtualization saves us the cost of physical machines such as servers and hardware. It is also environmentally friendly because we save electricity when the server usage is low. It allows any organization to run multiple operating systems (operating system).
• Agile Activation - Through cloud virtualization, we enable much more flexible operations that are more efficient and agile assistants. More complex scientific or technical problems can be solved from the point of view of grid computing obtained through cloud virtualization. It also avoids the need to recover data from corrupted devices.
• Promotes high availability and disaster recovery.
• Efficient and flexible data transfer - In cloud virtualization, users don't have to search hard drives or storage for data transfer or recovery. This can be done almost at any time using cloud virtualization. Finding and transmitting or retrieving data is much easier.
• There is no risk of system failure - in cloud virtualization, the risk of system failure is eliminated because data stored in the cloud can be recovered or transferred from any device at any time. In the traditional scenario, it is possible that while the operation is taking place, the server may hang, which can ultimately affect the operational functions of the organization. Clustering is also enabled in cloud virtualization so that if one server goes down, the other is always ready to take over.

To draw conclusions

In this article, we learned the definition of cloud virtualization while working behind it. We also looked at the types of cloud virtualization and the benefits of cloud virtualization today. So any organization can easily activate a robust cloud computing mechanism using virtualization.
