Application streaming simplifies application delivery to users by
virtualizing applications on client devices. Administrators can install and
configure an application centrally and deliver it to any desktop on demand.
Use the application streaming feature to install and configure an
application on one file server in your App Hub, publish the application using
the XenApp publishing wizard, and deliver it to any desktop or server on
demand. To upgrade or patch an application, you make the updates only in the
location where you stored the application. Application streaming augments
application delivery not only to user desktops and virtual desktops, but also
to servers in your server farms.
