8. SO – the Four Tenets  Boundaries are Explicit  Services are Autonomous  Services Share Schema and Contract, not Class  Service Compatibility is based upon Policy

9. SOA – Basic Patterns  Document Processor  “How do you create a simple to use, well defined contract that remains compliant with the SO design tenets?”  Loose-coupling  Represent a business process as a complete unit of work  Idempotent Message  How can you ensure messages are idempotent  Insist on a unique “Unit of Work” ID in each message  Reservation  How can you maintain data consistency across a long running process?  Tentative operations  Confirmation, Cancellation, Timeout  Service Compatibility is based upon Policy

10. A SOA – Baseline XML RDBMS

11. SO – Common Customer Database  People have more than 1 Policy  Have to deal with more than 1 system – not happy  Ownership  Services for change  Replication, Versioning and Notification  Semantics  Keys

12. SOA - Composability

13. Conclusion  Service Orientation is Important for Insurers  Systems will change to loosely-coupled asynchronous collections of services  Far fewer assumptions, consistent architecture is essential  Tools, methodology and language need work
