ABSTRACT

The goal of the DoD enterprise integration should be to create a "distributed and shared" information environment and ecosystem that supports delivery of products, functions, or services. This becomes an even greater challenge when DoD organizations and resources are distributed throughout the world, stove piped and accustomed to working their own way. Instead of static composition (with dynamic objects and dynamic binding) in the Object-Oriented (OO) approach, SOA allows dynamic composition at runtime, requiring knowledge of the service interfaces only. This includes, dynamic service discovery and matching runtime ranking and selection of services runtime collaboration establishment and runtime interoperability verification Dynamic Architecture via Dynamic Composition. Dynamic composition: occurs during the system modeling and assembling stages. SOA applications can use the same set of services to compose application architectures with different topologies.
