You can provide sets of more specialized applications to specific users through app layers, independent of the core applications that are generally distributed with the common base layer.
You can capture an app layer that contains a single application, or a suite of applications from the same vendor. You can create app layers to include applications relevant for a specific department or group. You can combine app layers with other app layers and deploy them on any compatible endpoint.
You define and deliver app layers by capturing an app layer and then assigning them to endpoints. See Assigning App Layers.
The app layer capture process creates a snapshot of designated applications installed on a live reference machine, which is generalized for mass deployment.
You can use a CVD as the reference CVD for app layer purposes. A base layer does not need to be present on the reference machine.
