Federated architecture

Federated architecture (FA) is a pattern in enterprise architecture that allows interoperability and information sharing between semi-autonomous de-centrally organized lines of business (LOBs), information technology systems and applications.

This is an approach to the coordinated sharing and exchange of information which is organized by models, which are describing common concepts and behavior. The pattern emphasizes a controlled sharing and exchange of information among autonomous components by communication via messages. Highest possible autonomy shall be given to the different cooperating components. In return they are expected to adhere to common models by using defined interfaces.
