  4. 4. <ul><li>Standards (including open source) for interoperability </li></ul><ul><li>Self-defined, loosely coupled interfaces </li></ul><ul><li>Tools to visualize and integrate existing assets </li></ul><ul><li>Model Driven Architecture (MDA) </li></ul><ul><li>Service Oriented Architecture (SOA) </li></ul><ul><li>Business Innovation & Optimization </li></ul>But … Technology Applied Correctly can Pave the Way for successful Business Innovation Outsourced Supplier Case Study: Procure to Pay Process Shared Service Division Customer
  5. 5. What’s this “Service Thing?” Message M1, M2, … … Op1, inMsg1, outMsg1, faultMsg1 Op2, inMsg2, outMsg2, faultMsg2 … … … “ Those lying IMS swine. Those are stored procedures.” “ You whipper snapper, we Invented that in IMS in 1923.” “ .NET. I like it.” WSDL Nein! Das ist eine IDOC “ That’s my simul. package!”
  6. 6. What is Service-Oriented Architecture (SOA) ? <ul><li>SOA is different things to different people : </li></ul><ul><ul><li>a set of services that a business wants to expose to their customers and partners, or other portions of the organization </li></ul></ul><ul><ul><li>an architectural style which requires a service provider, requestor and a service description </li></ul></ul><ul><ul><li>a set of architectural principles, patterns and criteria which address characteristics such as modularity, encapsulation, loose coupling, separation of concerns, reuse, composability </li></ul></ul><ul><ul><li>a programming model complete with standards, tools and technologies such as Web Services </li></ul></ul><ul><ul><li>A set of standards </li></ul></ul>Business Executive, Consultant Architect Developer
  7. 7. SOA Defining Concepts Universal Connectivity: Integrates most diverse environments, bridging protocols, languages, platforms, APIs and messaging paradigms – providing scale and scope of integration required by today’s extended enterprise Service Orientation : Facilitates loose coupling between software components Incremental Integration : Start small and plug in capability to enrich your implementation as needs dictate Open, standards-based : Open APIs and protocols support the interoperability and substitution of middleware from multiple vendors Event Orientation: Decouples applications that publish business events from subscribing applications Flexibility: A variety of options for persistence, reliability, security, availability... Deploy where required, manage centrally
  8. 8. What’s Different about Web Services? <ul><li>Haven’t we heard this before? </li></ul><ul><ul><li>Structured programming and modules? </li></ul></ul><ul><ul><li>Message Passing/Driven Systems? </li></ul></ul><ul><ul><li>Remote Procedure Calls? </li></ul></ul><ul><ul><li>OO Languages? </li></ul></ul><ul><ul><li>CORBA, Distributed Smalltalk </li></ul></ul><ul><ul><li>J2EE </li></ul></ul><ul><li>This time we really mean it. No kidding. </li></ul><ul><li>If you can’t take a joke, you shouldn’t be using distributed systems. </li></ul><ul><li>There are some differences </li></ul><ul><ul><li>Microsoft supports this model </li></ul></ul><ul><ul><li>XML is more language and implementation agnostic. </li></ul></ul><ul><ul><li>WSDL, WS-Interop include RPC and Messaging from day one; One is not added to the other. </li></ul></ul><ul><ul><li>XML and WSDL is more forgiving of change in messages and evolution of interfaces. </li></ul></ul><ul><ul><li>Common model for “services/impls,” “data in DB,” “data in flight.” </li></ul></ul>
  9. 9. “Web Services, A Nascent Component Model” Prolog Types Messages Bindings Policy Control Descriptors Deployment Descriptors Operations Port Types JMS/MQ HTTP IIOP … … Impl. Stub Required Interfaces ESB Container “ Resources” “ Abstract Process”
  10. 10. Simplifying Development <ul><li>This is crazy. </li></ul><ul><li>Programmers want to build a “part” that implements a “basic building block” and then aggregate them together </li></ul>Daddy, Mommy gave me these documents to convert. What type of EJB do you want to build? Um. I do not want to build an EJB. You see, Mommy gave me these … Maybe you didn’t understand the question. Your choices are SLSB, SFSB, CMP Entity, BMP Entity, MDB You’re not very nice.

  19. 19. Implementing Patterns <ul><li>Patterns may be implemented as process guidance or may be codified within tooling </li></ul>The solution described by a pattern may be implemented in a component, or across several components, or in a service. There are various codifications of patterns. <ul><li>Configurable Component : parameterized software component implementing one or more patterns; may be published as a service </li></ul><ul><li>RSA Transform, Pattern : implements a pattern through actions which modify model elements and other artifacts </li></ul><ul><li>Template : contains sections marked for substitution with parameters supplied by the user </li></ul>RSA – Rational Software Architect recognizes & documents + creates (later) uses customizes an asset The codified pattern may be further customized by less skilled users.
