Bettering Performance By Using Hosted Virtual Desktops


by Melanie Vaughn


Computer networking is perhaps one of the most powerful and essential concepts that are revolutionizing the computing process. In this way virtualization is currently possible. With the use of this technique remotely located resources can be shared as if they were physically present. Hosted virtual desktops represent such an implementation.

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.

Basically this kind of configuration can ensure that powerful applications are executed on thin client. In this approach the server carries out the processing which remains transparent to the client. However this cannot be executed on the client because of the overwhelming hardware demands that includes memory and processor power. Therefore within such an arrangement the server performs the computing and passes the results to the thin client which may be a smart phone or a similar mobile computing device.

This configuration is referred to as virtualization which is the main concept used in cloud computing. Such an arrangement enables powerful applications with a demand for enormous processing power and memory to run on thin client. Smart phone utilize this configuration which is also the case with other mobile computing devices that have limited capacity. In this case hardware software and platform are available as services that can be paid for on demand.

Therefore it is now possible to remotely accomplish computing requirements that would otherwise require powerful hardware. As such virtualization ensures that the remote server covers all the resource hungry applications and sends the results back. Most of these applications cannot be handled by the thin client.

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
