Each application represents a collection of packaged versions of that application. Users, Groups, Computers, or OUs can be entitled to receive the current package or a specific package version. You can use the Applications tab to create an application or application package, assign an application to an entity, and other management tasks.

The Applications summary page and the application details page (for every application) contain information about the application name, owner, status, and GUID, timestamp of the last synchronization operation between the source and target (Last Synchronized), entities assigned to an Application, computer prefixes associated with non-computer entities (Users, Groups, and OUs) and a list of application packages.
Note: The Last Synchronized field is displayed only for applications that are synchronized to the target.

On the Applications summary page, you can also perform some of the operations such as assign or unassign an application from an entity, create a package for the application, and manage the application. If your App Volumes instance is a target, then the application can be managed (edit and delete) only at the source. In such a case, the manage source capability is also available for the application on the summary page.

Application GUID helps in determining whether a replicated (or synchronized) application package is associated with the correct application. During synchronization, the application GUID on the target instance must match the application GUID on the source. This ensures that the correct application properties are synchronized from the source to the target.

For an understanding about application synchronization, see Configure Multiple App Volumes Instances for Application Synchronization. For specific information about managing synchronized applications and packages at the source instance, see Manage a Synchronized App Volumes Application at the Source.
