Improving Performance By Using Hosted Virtual Desktops

By Mamie Conrad


Virtualization as a concept in computing that has introduced a whole new range of possibilities. Generally with such a concept it is possible to run applications that require a lot of memory and processing power on thin client. This is accomplished when the client accesses instances of the application running on a powerful server. In this way it appears as though the application was actually running locally. This adaptation is typical of the hosted virtual desktops that operate on this concept.

This is what is called client virtualization that entails separating the personal computer desktop environment from the physical machine. Based on the client server model this arrangement enables instances of the PC environment to run on the server through a virtual desktop interface (VDI). In this way smart phones or thin clients can execute demanding and powerful application on their local machines unaware that the processing is actually taking place on a server in the background.

Therefore in this way applications that have higher hardware demands can run on thin clients. The process will normally be transparent to the user who all the time assumes that the application is actually running locally. Generally all the processes are executed within the server operating system.

In this way many user instances can be available from the server. These different users can have access to each of their unique environments running concurrently on the server. In this way every user runs a personalized session unaware that it is on the server and that there are more than one user running their applications remotely.

Generally the benefit that accrues from such a concept includes the ability to support remote administration. Therefore using this set up various administrators can have their own unique VDI instances on the server. From these different VDI each can be able to carry on their individualized tasks all at the same time. Basically the controlling server works just like the local console or PC

Typically a number of advantages are associated with this method of computing. Generally with a demand for more desktop environment instances can be created and stored on the server. As such several users can simultaneously have access to the same instance and thereby share in the processing. The centralized approach will enhance resource management and eventually improve output.

Generally the remote access process is a secured activity. As such data integrity is maintained and even enhanced when this technique is implemented. Other benefits like longer refresh cycles are viable with this technique. This enables an environment where the users logged on to the server cannot notice any lapses in their processing even when they are many who are logged on the server at the same time.

Generally the implementation of the VDI can be accomplished in a number of ways. This includes the centralized and hosted approaches where the application runs completely on the server. It may also be necessary to implement remote synchronization where a client makes a copy of the VDI instance on to the local machine. Ultimately with such a growing need for virtualization implementing hosted virtual desktops is a viable option.
