  2. Agenda • Introduction • SOA Reference Architecture • SOA Roadmap • SOA Governance • Summary

  3. Service Oriented Architecture Different Things to Different People Roles Capabilities that a business wants to expose as a set of services to clients and partner organizations Business An architectural style that requires a service provider, requestor and a service description. It addresses characteristics such as loose coupling, reuse and simple and composite implementations Architecture A programming model complete with standards, tools, methods and technologies such as Web services Implementation A set of agreementsamong service requestors and service providers that specify the quality of service and identify key business and IT metrics Operations

  4. The SOA Lifecycle • Discover • Construct & Test • Compose • Integrate people • Integrate processes • Manage and integrate information • Gather requirements • Model & Simulate • Design • Manage applications & services • Manage identity & compliance • Monitor business metrics • Financial transparency • Business/IT alignment • Process control

  5. Aligning Business and IT Objectives Enterprise Architecture • Reference • Architecture Governance Roadmap SOA and Enterprise Architecture: A Common Goal AccelerateTime to Market Function(Service Definition) IncreaseRevenue Security &Compliance Performance &Quality (KPI) ReduceCosts ITObjectives BusinessObjectives

  6. SOA: The Focus of the Enterprise Architect Deliverable Description Overview SOA Reference Architecture The SOA Reference Architecture defines a reference framework and corresponding IT principles for SOA implementation projects SOA Roadmap The Roadmap is used to create a tailored transition plan for moving toward the SOA Reference Architecture Strategic Vision Incremental Adoption SOA Governance Model The SOA Governance Model defines the decision rights along with the associated measurements and controls

  7. Agenda • Introduction • SOA Reference Architecture • Providing a comprehensive model • SOA Roadmap • SOA Governance • Summary

  14. Agenda • Introduction • SOA Reference Architecture • SOA Roadmap • Relating business and IT objectives • SOA Governance • Summary

  15. SOA Roadmap: A Plan for Adopting SOA SOA Goal • Market return through transformation: quicker time to production, lower costs, competitive differentiation Two Primary Roadmap Perspectives • Strategic VisionBusiness and IT statement of direction which can be used as a guideline for decision making, organizational buy-in, standards adoption • Project PlansImplementation projects to meet immediate needs of the current business drivers Market Return through Transformation Strategic Vision Revenue and Profit Incremental Adoption Time

  16. Assess current state Determine future state Develop Roadmaps Identify required capabilities and initiatives Roadmaps: Building Plans In Context Business Goals and Imperatives BusinessFunction Services Information Services Domain of Capability CommonIT Services Infrastructure Services Discrete PartialIntegration EnterpriseIntegration Partner Collaboration DynamicPartner Collaboration Scope of Services

  17. SOA Adoption Considerations • Business Drivers • Accelerate time to market • Reduce costs • Increase revenue • Reduce risk and exposure • Organizational Readiness • Executive support and sponsorship • Skills • Current Architecture and Environments • Build and Runtime • Degree of heterogeneity • Operational Readiness • Ability to monitor and manage current operations • Integration of monitoring functions into production environments

  18. Agenda • Introduction • SOA Reference Architecture • SOA Roadmap • SOA Governance • Executing for success • Summary

  19. Establishing decision making rights associated with IT Establishing mechanisms and policies used to measure and control the way IT decisions are made and carried out What is Governance? SOA Governance is a catalyst for improving overall IT Governance IT Governance SOA Governance Extension of IT governance focused on the lifecycle of services to ensure the business value of SOA

  20. Why SOA Governance Matters SOA Governance empowers teams to innovate • Realize business benefits of SOA • Business process flexibility • Improved time to market • Mitigate business risk and regain control • Maintaining quality of service • Ensuring consistency of service • Improved team effectiveness • Measuring the right things • Communicating clearly between business and IT

  21. Agenda • Introduction • SOA Reference Architecture • SOA Roadmap • SOA Governance • Summary

  22. SOA for the Enterprise Architect … • Understand your business goals, drivers, and context • Understand your current environment • Development, Runtime, and Management • Establish a Roadmap • Find appropriate starting point • Determine the development and runtime requirements • Leverage Separation of Concerns and the SOA Programming Model • Establish Governance • Appropriate for your company culture and environment
