Published Desktop Vs. Virtual Desktop : Comparison of Desktop Virtualization

Published Desktop Vs. Virtual Desktop will be compared using a cost-benefit analysis and to conclude with an analysis to investigate the results obtained. Through consolidation of virtualization and server environments, now people are looking for a way to virtualize desktops. The requirement for a virtual desktop depends on who is using or how this is to be used, due to the different approaches these points are highlighted and evaluated here in the context of desktop virtualization. There are mainly two alternatives – Published Desktop and Virtual Desktop for the sake of discussion here. What lies behind these technologies and how to run a direct comparison is within this article on Published Desktop Vs. Virtual Desktop.

Published Desktop Vs. Virtual Desktop : Previous Theoretical Articles

Few previous articles need to to be cited within this article :

1. Desktop Environment and Virtualization :Desktop Virtualization provides a complete work environment. Custom configured operating system of the guest systems are stored on the host systems.
2. Benefits of Desktop Virtualization for Business :This article will give an overview on the topic Benefits of Desktop Virtualization for Business.
3. Desktop Virtualization with VMware View :Intel VT is being delivered by Intel with various added proprietary technologies and is targated for server virtualization. The reason is, the usage of Server Virtualization will increase in next few years.

Published Desktop Vs. Virtual Desktop : Structure and Objective

For the sake of comparison of Published Desktop Vs. Virtual Desktop, a cost-benefit analysis is carried out (in my original paper, a brief summary is provided here). This is followed by the designation and explanation of the analysis and their description. The analysis of whether or to what extent the criteria are covered by the alternatives is also discussed. In this article, two methods is compared; on one hand Published desktops and on the other virtual desktops. These are compared using a cost-benefit analysis and conclude with a sensitivity analysis to investigate the results obtained.

Definition of Cost Benefit Analysis

Definition of Cost Benefit Analysis : Cost-benefit analysis is the analysis of a set of complex alternatives with the purpose to arrange the elements of the set according to the preference(s) of the decision maker with respect to a multidimensional target system. The conclusion is drawn by specifying the utility values ??and total values ??of the alternatives. In carrying out the cost-benefit analysis there are some advantages :

1. The method of cost-benefit analysis is transparent and easy to understand.
2. The alternatives are directly compared.
3. The priorities can be changed depending on the decision maker.

The profits arising from the cost-benefit analysis has disadvantages too:

1. Assessment of alternative is subjective.
2. The selection criteria can be chosen wrong.

In the cost-benefit analysis subjective factors are excluded as far as possible and replaced by objective factors.

Published Desktop Vs. Virtual Desktop : Desktop Virtualization and Virtual Desktop

The desktop virtualization is a method which allows multiple users to execute application programs on a remote computer (host) simultaneously and independently in respect to each other. Such desktop virtualization can be configured individually for each user and operating system(s) in the host operating system instance. The users thus operate in a virtual environment system which behaves like an ordinary local computer. A similar procedure has been around since 1998, meant here is the driver is server terminal technology. Here, an operating system is provided by a server, but in this case several users must share the operating system and the server’s resources and are not isolated from each other as in case of virtualization. Through desktop virtualization, the operating costs can be reduced such as electricity costs since existing servers are optimally utilized so that the server infrastructure can be optimized and reduced if necessary. Desktop virtualization can also be said to promote Green IT.

Virtual Desktop and Virtual Desktop Infrastructure (VDI) is the provision of a client operating system that is running on a physical server. The accounts of the physical workstation will be replaced by physical thin Clint on which the Virtual PC is running. Multiple virtual PCs on the server are provided for virtualization which usually operate in isolation from each other. Each user has its own virtual machine and therefore must share resources, because each desktop is entitled to a fixed number of resources, which is independent of the other VM and can not be influenced. Therefore be in Virtual Desktops – data, user settings, operating system and the desktop, that is the graphical interface which virtualizes. With virtual desktops, there is a default image that is loaded when starting a VM and then depending on the needs of the user applications are added. In the same way also the user data is provided.

Published Desktop Vs. Virtual Desktop : Published Desktop

Published desktop uses Microsoft Terminal Services (formerly Terminal Server) to provide a desktop interface on a server via remote access. Here this desktop is based on a single server-side operating system installation, which publishes the desktop interface in the form of a session. Any computing power needed is not dependent on the client but on the connected server.

Published Desktop Vs. Virtual Desktop : Comparison

The published desktop technology has been able to prevail because of the easy to realize infrastructure. Here, however, the weaknesses is in the area of usability and networking. Note that the network load and user friendliness can be rated better with Virtual Desktop than with Published desktop. The criteria and their weighting are not to be understood as a measure, because these represent only the subjective perception of a person. Using a sensitivity analysis of the method comparison is viewed from a different standpoint.

Hosted Virtual Desktops are in the valley of disappointment. This means that the initial expectations of the product were not met at the earliest important time for the market. Generally one can say that the companies gain additional flexibility by desktop virtualization, this also results in the ability to deploy applications on the mobile devices. In addition to the flexibility, the operating costs can be reduced because the energy and maintenance costs are reduced with the use of thin clients.
