SCA Based Integration - Bindings EIS Import SCA Module B Web Service App SCA Import WS Import JMS Application WBI Adapter WebSphere Adapter Web Service App SCA Module A JMS App WBI Adapter WebSphere Adapter J2EE Application SCA Module A J2EE Application We have native ‘SCA’ bindings for SCA to SCA (modules). In addition to that, we allow SCA components to be called from (look left) a variety of client programming styles and we allow SCA programs to view a number of services as WSDL describe SOA services (look right) JCA JCA JMS Export JMS Import SCA Export WS Export EIS Export SCA Export WS Export SCA Import WS Import SLSB Import

SCA and SDO Standardization What we announced in November, 2005 A series of specifications aimed at developers building solutions and components using Service Oriented Architecture principles: – Service Component Architecture (SCA) – Service Data Objects (SDO) Meeting Customer Needs: – Simplification of Development (Simplify the enterprise developers life) – Composition and Implementation of Services – Multiple Language support (Java, C++, BPEL, PHP) – Flexible Quality of Service – Broad Industry Support – A procedure for obtaining community feedback Early Code Availability – Runtime offering for Developers, supporting the programming model in C++ and Java The specs on the IBM web site:

    30. 30. Conclusion and Summary
    31. 31. Patterns Across Products <ul><li>Things that we’re seeing </li></ul><ul><ul><li>Adaptor + Process Server - almost always have an adaptor or 2 in the mix </li></ul></ul><ul><ul><li>Broker + Process Server </li></ul></ul><ul><ul><li>Portal + Process Server </li></ul></ul><ul><ul><li>Many Modeler  WID/WPS projects, but Modeler still being used by architects in many of these scenarios </li></ul></ul><ul><ul><li>WAS/J2EE + Process Server - New projects, that might have previously focused on J2EE exclusively, now want to incorporate ‘process’ and thus SOA. </li></ul></ul><ul><ul><li>Periodic WebSphere Partner Gateway plus Process Server </li></ul></ul><ul><ul><li>Modeler  WID  RSA </li></ul></ul><ul><ul><li>Expect more Content Manager + Process Server (we saw a few WBI-SF + CM) </li></ul></ul><ul><li>Related Realties </li></ul><ul><ul><li>Lots of J2EE applications that now we want to make services of </li></ul></ul><ul><ul><li>Limited ‘true’ SOA design skills </li></ul></ul>
    32. 32. Applying the V6.0 Stack to Business Problems <ul><li>Reality is: </li></ul><ul><ul><li>The ‘no code’ objective is only partially met and in fact, so far we see a few POJOs in almost everything we do. </li></ul></ul><ul><ul><li>We need the products to work better together with in WBI and across AIM and SWG. We know this and are working on this. </li></ul></ul><ul><li>Problems we are solving today </li></ul><ul><ul><li>Business process automation </li></ul></ul><ul><ul><li>Service creation </li></ul></ul><ul><ul><li>Integration of existing Assets </li></ul></ul><ul><ul><li>Production Deployment </li></ul></ul><ul><ul><li>Enable an SOA Culture to be born, grow and deliver business value </li></ul></ul><ul><ul><li>Connection to a lot of things </li></ul></ul><ul><li>Problems we will enable next </li></ul><ul><ul><li>Event Driven </li></ul></ul><ul><ul><li>Automatic Service Composition, Selection </li></ul></ul><ul><ul><li>Complete Business Monitoring of SOA </li></ul></ul><ul><ul><li>Completely dynamic SLA management </li></ul></ul><ul><ul><li>Integration of Registry thought at development and runtime </li></ul></ul><ul><ul><li>Complete Ubiquitous “Connection” </li></ul></ul><ul><ul><li>Dynamicity and Full support for the lifeCycle of SOA based solutions </li></ul></ul><ul><li>Problems we are not going to solve (yet) </li></ul><ul><ul><li>?
