Fairfax County Public Schools
IT staff at Fairfax County Public Schools (FCPS), a large district with 90,000 computers, had to manage and update many separate disk images. This complexity led to the deferral of most application deployment until hardware upgrades were done, which reduced application availability to teachers. At times, applications were deployed singly, adding to the maintenance complexity. Deployment could take four weeks, and then, teachers needed transition time. With Microsoft Application Virtualization version 4.5, IT staff can easily deploy images and applications, while maintaining 50 percent fewer images. IT staff can perform just-in-time application deployment dynamically, whenever they need to. Upgrades are less stressful for teachers because older application versions remain available to them. Teachers and students can access the applications they need from many more computers than before.
