Virtualization is a mechanism to separate a service from its fundamental physical delivery developed during the mainframe era. It could also be understood as being a virtual version of anything such as computer hardware.

It also includes utilizing specialized software to generate a virtual or softwarecreated version of a computing resource rather than the actual version.

Virtualization allows different operating systems and applications to operate on the same machine and on the same hardware at the same time, enhancing hardware usage and flexibility. EstNOC is a company based in Estonia that provides hosting and colocation data center services along with which they also offer cloud computing in Switzerland and other places.

Types of Virtualization

Network Virtualization

In cloud computing, network virtualization is a method of connecting the available resources in a network by dividing bandwidth into different channels, where each channel is distinguished and separated. They at the same time can stay unassigned completely or assigned to a particular server or device. The theory behind this is that the technology hides the network's true complexity by breaking it down into manageable chunks, similar to how a segmented hard drive makes managing files easier. Network virtualization in cloud computing is of two types: internal and external, where internal virtualization provides network capabilities to a single system and external virtualization connects multiple networks or parts into a virtual unit.

Storage Virtualization

Storage virtualization allows the user to combine the storage space of numerous networked storage devices into a simulated single storage device that can be managed from a single command console. This storage approach is commonly employed in storage area networks. By disguising the true and physically sophisticated storage architecture, storage manipulation in the cloud is mostly utilized for data backup, archiving, and recovery. Administrators can use software applications or hardwaresoftware hybrid equipment to implement it. Storage Virtualization is of two types block storage virtualization and file storage virtualization, where the block storage virtualization works before the existence of a file system as it replaces controllers and obtains at the disk level and the file storage virtualization works in order to enable filelevel access, the server that uses the storage must have software installed.

Desktop Virtualization

Desktop virtualization is by far the most common in the IT sector, utilized commonly in the workplace. Every user's desktop in this system is virtualized and stored on a common server, allowing the user to virtual access the desktop from any system device. This system also ensures data security by guaranteeing that all data transfers are carried out via secure protocols. This type of virtualization has a number of benefits, including user portability and easy mobility, as well as simple and effective management of software, its installation, and updates as well.

Application Virtualization

Application virtualization enables a user to access an application from a server from a remote location. The server keeps all of the application's personal data and other characteristics, yet it can still be run locally on a workstation over the internet. For example, a user needs to run two versions of the same software.

Hosted applications and packaged applications are two examples of technologies that leverage application virtualization.
