The application partitions are directory partitions that are copied to domain controllers and belong to the Azure Active Directory system. These domain controllers that are involved in the partitioning procedure keep a copy of the partition. Application partitions have the advantage of being able to be cloned to any individual domain controller, potentially leading to traffic reduction. Although domain directory partitions can transport their entire data to all the domains, application partitions in the domain area can only target one. This minimizes the need for application partitions and thereby increases their availability.
