GCube Accounting allows to collect information of the infrastructure usage and expose them for the interested consumer.

Architecture
The following picture shows the gCube Accounting architeture
The Accounting Architecture has been logically divided in three different layers.
All the developed component must respect this paradigm.
Accounting Enabling Layer
- accounting-lib
- accounting-analytics
- accounting-aggregator
Each enabling layer has its own correspondent backend implementation. Each backend implementation must be dynamically discovered at runtime. This allow to decouple the deployment of a different backend from the development of enabling layer. In other word each component on the enabling layer MUST NOT any dependency over a certain backed implementation. Furthermore, MUST NOT be any component in the infrastructure which depends by a specific backend library.
The only entitled software which can have a dependency against the backend component are the ones that allow to deploy and distribute a consistent infrastructure:
- bundles (e.g. smartgear-bundle, portal-bundle)
- provisioning script
Accounting Backend Layer
The actual backend is CouchDB
- accounting-lib-persistence-BACKEND (i.e. accounting-lib-persistence-couchdb)
- accounting-analytics-persistence-BACKEND (i.e. accounting-analytics-persistence-couchdb)
- accounting-aggregator-persistence-BACKEND (i.e. accounting-aggregator-persistence-couchdb)
Accounting Consumer Layer
In this layer we found not only the accounting consumer which retrieve information related to collected data (e.g. Accounting Manager Portlet) but also all the component which collect data and use accounting-lib to persist in a common pattern.
