A virtual desktop is a sophisticated software, which creates an interface environment in such a way that an end user can access, the personal resources like window, application, folder etc. stored in his/her own system, remotely from another system. To achieve this degree of success, the software must be installed on both the systems. The whole process is based on the concept of Virtualization technology. This technology enables the individual’s isolated computer, to separate the desktop environment from its physical existence. It is an application of discrete computing.
Concept of remote server
In Virtualization of the desktops, a remote server plays an important role. It is mainly responsible for creating and supporting a desktop environment. Through a virtual desktop, all the data of client’s device are stored in the server, so that it can keep intact with the device without the presence of the actual machine. In this way, an individual also can keep a backup of the system to recover from an accidental data loss. For this same reason, every organization and company maintain a centralized server. The idea is similar to the automated resort point of a PC.
The Virtualization follows a complex infrastructure of networking and communication to support the environment of desktops. There are several underlying layers that work behind it. Some of them are application layer, network layer, data link layer, psychical layer etc. Each of these layers is important to establish a connection and data transfer. Due to this complexity, the software is readily available with an additional administrative package to take care of the connection port.
Behind any kind of technology, performance, cost and security, these three things are considered most. The same is applicable here. For independent enterprises, it took extra cost and time to install the necessary software and OS on each machine separately. Instead of that, if the tech is integrated in just one machine capable of powerful computing i.e. having high configuration memory and processor, then it is possible to share a single resource by multiple end users concurrently.
The performance of the virtualized environment depends on delay time of transferring data from one PC to another. If the delay time increases, then the process of responding will slow down the client’s machine. But, the administrative capability of this software is great, so the synchronization process is always maintained among the devices. Besides, it provides a very high level of security as the access privilege is user based. Without proper authentication, no third party can operate any desktops from outside.
In this cutting edge of science, the idea like virtualized desktop environments is the only simplistic solution for all kind of enterprises and terminal users to overcome the barrier of physical relam.
