Have you ever wondered how other organizations like yours choose to deliver applications to their desktops virtual? As Citrix Consultant, I am constantly asked to provide this kind of "reality check."
I often relies on design cues in the office processing accelerator to help meet these types of questions. with over 8,500 registered projects in over 110 countries, the accelerator is probably the most extensive project database office processing real world in the world.
So let's take a look at what the accelerator tells us about how organizations are effectively deliver applications:
Chart: Application delivery combinations,% of projects
Source: Office design cues from the processing accelerator
approach the most widely used application delivery is to install on the virtual desktop (locally) and some set-Hosted (XenApp)
I can think of two good reasons why this combination is so popular.
1) a group of organizations decide not to use XenDesktop for all users, but only for a group of demanding users (ie developers or CAD engineers). In this scenario, the popular desktop applications are provided as published applications (using the existing XenApp environment), while specific applications in the user-as Visual Studio or CATIA- are installed directly on the virtual desktop. Besides centralized maintenance of desktop applications that also releases a fair amount of CPU / memory on virtual desktops. Especially in CAD scenarios each MB in RAM account.
2) The other group of organizations decide otherwise, and to grant to all users a virtual office. In this scenario, common desktop applications are usually installed right in the virtual desktop image. XenApp then provide access to applications "special" that are either user or a specific department and can not be integrated into the base image (compatibility / flexibility), require a back end connection at high speed ( ie work stations are located in another datacenter) or need to be updated frequently. In so doing, it is possible to use a single virtual image office for a wide variety of user groups. In addition, it is possible to minimize the maintenance cycles on the image.

This scenario has similarities to the one above, but the reasons for choosing it are probably different. In many cases, it is chosen by organizations that have standardized on virtual desktops but do not have a XenApp experience or whose applications are not compatible with XenApp (access to knowledge required local materials). So all the basic applications are installed in the virtual desktop image and user / role specific applications are distributed to customers through streaming packets. This combination offers the same advantages as the above scenario, but offers an advantage in the application testing aside. Since the application streaming isolates the integration testing of individual applications streaming becomes almost obsolete. Regression testing is necessary in cases where the integration between the applications is required (inter-isolation communication).
Have you found any other ideas in the table above?
