Towards a Federated SOA Model in Achieving Data Interoperability in DoD
Abstract
The Department of Defense (DoD) is undergoing a progressive transformation towards a Net-Centric enterprise, and SOA has become a major enabling factor in driving the transformation. One of the major challenges facing many SOA-based programs in DoD is how to define a SOA model that is robust and scalable enough to meet mission-specific needs, while satisfying the Net-Centric requirements for data sharing across the multiple Services and Agencies in the Department. While there have been many SOA initiatives existed in DoD with various successes, data and service interoperability across multiple organizations are still limited due to lack of a coherent and overarching SOA model. In this paper, two different types of SOA models, a centralized and a fully distributed model, are discussed with respect to data interoperability and enterprise scalability. To achieve interoperability, a federated SOA model is introduced, along with a proposed strategy towards implementing a federated enterprise using the SOA principles. The identification and use of enterprise core services will be discussed, with respect to service discovery, security and support of disconnected operations. The benefits in data interoperability of the model and its applicability are demonstrated via a concrete case study on an existing Net-Centric program in DoD.
