How To Gain Computing Efficiency With Hosted Virtual Desktops

By Melanie Vaughn


Computer networking as a concept has changed the way computing carries on. Virtualization is a product of such a concept. In this implementation resources that were otherwise remote can be shared by utilizing the computer network. As such the resources here are availed just as if they were physically present. Hosted virtual desktops are implemented using this type of technique.

The client server model of computing as the basis of such a technique has a number of benefits. Most of these are made possible through the server operating system components. Such a component is like the virtual desktop interface (VDI). This model also enables the implementation of a centralized resource management approach. This will cover such details like data and resources management as well as security.

The VDI will enable a network administrator to initiate and host various user sessions all running on the server. This component of the server operating system allows the operator to identify and assign different user sessions which can then be executed in shareable mode. By using this approach the user will have their own session that is transparently executing on the server as though it was on their personal computer.

In this way those powerful resource hungry applications can be executed on thin client. The configuration enables the server to run the applications in the background a process that is performed on behalf of the thin client. This is the case because the application may outstrip the thin client resources as far as memory and processor power is concerned. In this case a smart phone or similar mobile computing device is a typical thin client within such a configuration.

This type of arrangement is referred to as virtualization and is the basis of such applications like the cloud computing. In this way a thin client is able to remotely run applications that have a high processor and memory demand than what has been provided by the thin client. In this way smart phones and other mobile computing devices carry out powerful computing applications. The software hardware and platform are available within such an arrangement at a fee and on demand.

Currently it is possible to remotely carry out computing activities that require powerful hardware. With virtualization the remotely located computer will perform the processing transparently in the background. The results will be transferred back to the thin client on completion. This is necessary because the thin client cannot sustain such an application due to limited resources.

The VDI enabled sessions can be accomplished based on a number of approaches. Typically a centralized approach is where everything runs on the server that is remote to the client. Additionally the remote synchronization approach can also be implemented. In this latter case duplicate copies of the instances are also execute by the client concurrently. Generally such configurations carry on in a transparent manner whereby the user assumes that the applications are executing on the local machine.

The typical application of hosted virtual desktops can involve different administrators logged on to the same server to perform different administrative tasks. The server operating system through the VDI can implement this type of arrangement. Generally each administrator will have their own independent session all of which are running on a single server
