Active and Available Inventory (AAI) is the OpenECOMP subsystem that provides real-time views of available Resources, Services, Products, Offers, and their relationships. AAI (sometimes referred to as A&AI) not only forms a registry of active, available, and assigned assets, it also maintains up-to-date views of the multidimensional relationships among these assets, including their relevance to different components of OpenECOMP.
In addition to inventory and topology management, AAI provides the ability to do inventory administration, reporting and notification. Data in AAI is continually updated in real-time as changes are made within the cloud. Because AAI is metadata-driven, new inventory item types can be added dynamically and quickly with Service Design and Creation (SDC) catalog definitions, using the AAI model loader, thus eliminating the need for lengthy development cycles.

In addition, AAI data is provided from the OpenECOMP Portal, enabling a layered, graphical view of the virtual cloud network.
