  2. Agenda • Business Driven Development for SOA • Software Development Platform for Business Driven Development and SOA • Summary

  3. What is Business Driven Development?Development as a Business Process An integrated approach to software development that aligns line-of-business, development and operations teams to improve business performance • Align Technology and Business priorities • Improve efficiency and responsiveness • Address Governance and Compliance requirements Software development becomes a driver of competitive advantage

  4. Three Key Concepts To Adapt for Business Driven Development Service Oriented ArchitectureFocus on Flexibility and Reuse • An approach for designing and implementing distributed systems that allows a tight correlation between the business model and the IT implementation Model Driven ArchitectureFocus on Efficiency and Quality • A style of enterprise application development and integration based on using automated tools to build system independent models and transform them into efficient implementations Business Innovation and OptimizationFocus on Responsiveness and Optimization • A monitoring and management approach that leverages integrated resources to achieve aligned, accountable, and action-oriented business operations

  6. Demo SOA End-2-End High Level Business Process Tasks = I/T Services Granularity SOA Bridges the Gap between Business and I/T Business Models Identify Process Tasks How do I optimize my business processes? Business and I/T can use a common language a.k.a. “Process Integration” How do I integrate to my existing systems? I/T Components exposed as SOA Services

  7. What is Service Oriented Architecture (SOA) ? … a service? A repeatable business task – e.g., check customer credit; open new account … service orientation? A way of integrating your business as linked servicesand the outcomes that they bring … service oriented architecture (SOA)? An IT architectural style that supports service orientation … a composite application? A set of related & integrated services that support a business process built on an SOA

  8. Why should IT use Service Oriented Architecture? Organizations are composed of People Processes they run Information they use

  9. Business people drive processes that involve much information

  10. Organizations have been service-oriented for years… Accounts Payable Human Resources Organizations are Service Oriented Payroll Time & Attendance

  11. Why should I/T use Service Oriented Architecture? • I/T should use SOA for the same reasons businesses are organized by services: • More measurable and accountable • For efficiency and optimization • Specialization and best practices • Well-defined interaction and processes • Independently scalable • Reduce duplication and reuse assets • To isolate change & manage flexibility

  12. Flexibility SOA builds flexibility on your current investments The next stage of integration Service Orientated Integration Enterprise Application Integration (EAI) Messaging Backbone • Integration and choreography of services through an Enterprise Service Bus • Flexible connections with well defined, standards-based interfaces • EAI connects applications via a centralized hub • Easier to manage larger number of connections • Point-to-Point connection between applications • Simple, basic connectivity As Patterns Have Evolved, So Has IBM

  13. Applications can be composed of or exposed as services

  14. Applications can implement business process workflows… by using services Determine Customer Eligibility Retrieve Credit Report Request additional info Generate decline Etc…. Business Process is implemented by integrating services

  15. User Interaction Logic Data Logic Integration Logic Process Logic Business Rules Monitoring & Management Logic What is in an application?

  16. Business Services Business Function User Interaction Logic Data Logic Integration Logic Process Logic Business Rules Monitoring & Management Logic Integration through “service orientation”

  17. User Interaction Logic Data Logic Integration Logic Process Logic Business Rules Monitoring & Management Logic Business Services Application Infrastructure(Tools help you Model & Assemble these) (Server infrastructure is out-of-the-box) • Modeled by business stakeholders • Realized by I/T stakeholders • Transforming existing assets • Creating new assets • Modular and re-usable • Composed into applications, processes,and composite services

  18. Design ( Models, Patterns, Templates, Policy ) Composition User Interaction Invocation Information BusinessComponents SOA Programming Model • Design • Focus on business design modeling, simplification, and role-based collaboration • Use of declarative policy to control execution behavior and relationships • Invocation • Loosely-coupled call-style and event-driven interconnection of services with built-in support for topology transparency, mediation, and brokering featuring standards-based interoperability • User Interaction • Dynamic support for people integration into the business design • Composition of Business-level Apps • Wired assembly of services to form business applications, workflows, & service orchestration • Information • Built-in access to service state, disconnected service-data exchange, information composition and transformation • Business Components • Composable and reusable services

  19. Design ( Models, Patterns, Templates, Policy ) Composition User Interaction Invocation Information BusinessComponents SOA Programming Model Supported by Key Standards • JavaServer Faces • Standard way to construct user interfaces for web applications, JSR 168 portlets, etc. • MVC based User Interaction Framework • Service Component Architecture (SCA) • Calling anything efficiently as a service, local or remote, human or system, cross-platform and open standards • Component services programming model which provides a consistent framework for assembling solutions • Jointly developed/endorsed by IBM, BEA, IONA, Oracle, SAP, and Sybase • Apache Open Source Incubator Project • http://incubator.apache.org/tuscany/ • Service Data Objects (SDO) • Uniform (technology independent) way to represent data • Provides Single abstraction (common API) across JDBC ResultSet, JCA Record, XML DOM, JAXB, Entity EJB, CMI (for MQ messages), and so on • Co-developed by IBM and BEA • Business Process Execution Language (WS-BPEL) • Standard way to choreograph processes (a.k.a. orchestrate services) standardized through OASIS

  20. Where we’ve come from….

  21. Where we are…a simplified SOA Programming Model

  22. SOA Lifecycle Bridges the Gap Between Business and I/TThe 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

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