Cloud computing virtualization can be described as developing a virtual version of a desktop, operating system, storage device, server, or network resources. It is simply a methodology or process that lets several businesses or consumers share a single physical instance of a resource or application. It facilitates decoupling the service from the actual delivery of the service. Multiple operating systems and apps can then operate on the same computer and hardware with the aid of this technology.
Virtualization is very important in cloud computing technologies. Normally, users in cloud computing exchange data existing in the clouds, such as applications, but with virtualization, users share the infrastructure. For example, if the next version of that application is released, the cloud provider must give its users the most recent version, which is not practical because it is more expensive.
To address this issue, we primarily employ virtualization technologies. By utilizing cloud computing virtualization, third-party personnel manages all servers and software applications other cloud providers require. The cloud providers are obliged to pay the money monthly or annually.
1. Application Virtualization: Application virtualization enables a user to view an application from a server remotely. The server saves all personal information and other program characteristics, yet it may still be operated on a local desktop over the internet. For example, a user must run two separate versions of the same program.
2. Server Virtualization in Cloud Computing: This type of virtualization in which server resources are masked. The central server (physical server) is partitioned into numerous distinct virtual servers by altering the identification number and processors. As a result, each machine may run its operating system in isolation where each sub-server is aware of the primary server’s identity. It improves speed while lowering operational costs by relocating major server resources to a sub-server resource. Server virtualization in cloud computing aids in virtual migration, reduces energy usage, and lowers infrastructure costs, among other things.
3. Desktop Virtualization: Desktop virtualization allows users’ operating systems to be remotely stored on a data center server. It enables users to virtually access their desktop from any location using a separate machine. Users who need operating systems but not Windows Server will require a virtual desktop. The main advantages of desktop virtualization are user mobility, portability, and the ease of managing software installation, updates, and patches.
4. Data Virtualization: This type of virtualization is where data is gathered from many sources and stored in a central location. Without knowing more about the technical information, such as how data is collected, stored, formatted, and then arranged logically, its virtual view can be accessed remotely by its interested people, stakeholders, and users via the various cloud services.
5. Network Virtualization: It can operate several virtual networks, each with its control and data plan. It coexists on top of a single physical network, and it can be controlled by individuals who are possibly confidential to one another.
Network virtualization enables the creation and provisioning of virtual networks – routers, logical switches, load balancers, firewalls, Virtual Private Network (VPN), and workload security – in a matter of days or weeks.
6. Storage Virtualization: Storage virtualization in cloud computing refers to a collection of servers controlled by a virtual storage system. The servers have no idea where their data is kept and instead behave more like worker bees in a hive. It allows storage from numerous sources to be handled and used as if it were a single repository.
1. More flexible and efficient resource allocation
2. Disaster recovery and high availability
3. Increase the productivity of development
4. Allows the use of numerous operating systems
5. It brings down the cost of IT infrastructure
6. Pay for on-demand access to IT infrastructure
7. Remote access and scalability in a hurry
Virtualization in cloud computing entails running several operating systems on the same machine while exchanging all hardware resources. And it helps us provide a pool of IT resources so that we may share them to benefit the organization.
