Desktop virtualization is a process in which one or more computers serve as inputs to a central computer that manages all data and applications. This practice has many advantages in enterprise environments, and can potentially save time and money in the right environment.
In a standard network model, the user of a computer, its operating system, applications and running processes, and sends the data back and forth to other computers either directly or through a server that stores the network data to interact. In a virtualized desktop model, sometimes virtual desktop interface (VDI) referred to the central computer, not only retain the data, it also manages programs and processes applications. The terminals will be used by users shell representation of how such a main computer.
The main advantage of this configuration is that a person access to the same “computer” is on all systems on the network VDI. So especially for large companies, an employee can generally use a computer in his office, but must travel to other offices or to access their network from remote locations. Since the execution of server-side applications is the office of the employee to different terminals and a portable device, and accessible.
Network administration and technical support are simpler, if only a handful of computers that work and are on the remote computer as access points in operation. Computers can be added quickly to the network, such as new machines that do not require software installation to use VDI. By increasing the system’s requirements and require upgrades of hardware, the mainframe to update because the terminal cannot be strong enough to make the software must be running VDI. This also leads to potentially lower costs for equipment such as computers often require the speed of the interface and the minimum power to perform, and can even be acquired by outdated systems of another company. There is also less effort to install the programs, because programs must be installed on the host computer. The integrity of the data better, because they have created and modified on the server rather than on individual terminals, the network transmission.
The system is not without drawbacks. There is an increased level of complexity in establishing and maintaining a network VDI is compared to a conventional network. Communication problems within the network in all the affected computers useless, not having the opportunity, without access to the server function took place. Users will not be able to work without an active connection to the network, which means they do not necessarily have the opportunity to work from home, unless additional access has been agreed, and Internet user n is not down. It can also complicate to set up printers, faxes and other devices are working properly from their remote sites.
Not all business models and private benefit of a VDI, and the advantages and disadvantages should be weighed carefully because it is not easy to move from one network type to another.
