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 software-
created 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 hardware-software 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 file-level 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.
