   • Realizing and Preserving Intrinsic Interoperability

     The consequences of building silo-based and single-purpose applications have been well documented. As IT enterprises accumulate an ever-growing collection of disparate systems, the need to resort to fragile integration architectures results in convoluted environments that become increasingly burdensome and risky to evolve. Service-oriented architecture provides a direct alternative to this approach by establishing a method for the design of systems that are inherently compatible with each other. This leads to an opportunity to create a genuine level of interoperability that is intrinsic to each software program we build as a service. This method has been established and proven for years and has successfully realized concrete and measurable levels of intrinsic interoperability. In this session, the world’s top-selling SOA author will provide a tour of the steps and requirements for realizing intrinsic interoperability within solution design and implementation. The session concludes by highlighting the significance of governance controls required to continually preserve interoperability throughout the evolution of services and their underlying architectures in response to on-going business change.

8. Adjourn to Steering Division meetings

   • Realizing and Preserving Intrinsic Interoperability
8. Open Mic
   • Woody asks about similarity to Information Management concepts introduced 30 years ago. Communities, as groups of enterprises collaborating because it's the right thing to do, what examples can he offer from the recent experience? Thomas reports that the defense sector e.g. DOD has been very successful. They have moved through a governance framework into semantic web technologies well, with effective results. It may be that discipline is part of their culture… but he hasn't been as involved on the implementation side of late. Woody notes that organizations didn't follow info mgmt because of unwillingness to perform up front top down analysis. Thomas feels that SOA will work due to the balanced scope. Domain-based modeling has allowed them to stay away from an all-or-nothing risk and allows them to define a scope that is meaningful which allows them to proceed.
   • One attendee asks a question on coupling; SOA advocates a reduction in coupling and advocacy as part of the paradigm. Service logic to be decoupled from the API, decoupled from those that consume it. Dynamic media with REST binding solves some problems. Cloud computing has no formal models. Silos can be built in a cloud. Semantic web technology so far has the same weaknesses. It's about layers in architecture and representation.
   • Presentation will be made available on the wiki.

Meeting adjourned at 7:12 pm PDT to the Steering Division meetings.
