Plan your VM hosted apps deployment as part of planning your overall XenApp deployment. Determine which applications to deliver using VM hosted apps and consider which types of desktops are most appropriate for the applications you want to deliver, what privileges to give desktop users, and how to secure your desktop environment.
If your VM hosted apps deployment includes virtual machines, install your hosting infrastructure and Provisioning services separately from VM hosted apps site.
A VM hosted apps site can use a dedicated Web Interface server or share one with other VM hosted apps sites and XenApp server farms. When VM hosted apps site shares a Web Interface site with a XenApp server farm, users can access applications from both without regard to how the application is published.
