  3. Enterprise Computing History (Blank Page) © 2004 IBM Corporation

  4. 1st Generation Enterprise Computing • Discrete Business Applications within Enterprise • Coupled by manual or batch processing • Separate application sets like Order, Inventory, Accounting • Through print-out or screen-scraper • Local optimization on each business operation • Data silo issue © 2004 IBM Corporation

  5. 2nd Generation Enterprise Computing • Monolithic Integration with Package Apps around Business Process • ERP package integrates a set of application tightly but monolithic • Data silo issue resolved within ERP • Needs many customization to adopt • New business application packages create higher level data silo issue • Between application packages like CRM, e-commerce, SCM etc. • B2B and B2C create new integration needs across enterprises © 2004 IBM Corporation

  6. 3rd Generation Enterprise Computing • EAI needs by On-demand Business • ERP and monolithic application packages integration through EAI (Enterprise Application Integration) • Has to be responsive through entire processes as enterprise in network economy • Still tightly non-flexible integration between business processes • No dynamic partnership enabled • Difficult to change and create new process (70% of IT budget spent for current system-associated maintenance) • Difficult to change IT resource for business transaction fluctuation • Huge spike as e-commerce nature © 2004 IBM Corporation

  7. Next-Generation Enterprise Computing • Enterprise Application Needs for Network Economy • Build business process dynamically as composite services within Enterprise and across Enterprise • Disintegrate monolithic business processes • Long business transaction to complete a business process • Dynamic resource allocation for transaction fluctuation © 2004 IBM Corporation

Each institute will have ~10 physicists working on one or more channels; data for these channels should be cached by the institute server Pentium II 300 MHz Pentium II 300 MHz Pentium II 300 MHz Pentium II 300 MHz Tier 4 Physicist workstations Example of Scientific Application • Similar Requirements in Scientific Application • Build research process dynamically as composite services across Internet • Dynamic resource allocation through Internet • Science applications leap from discrete applications to Grid through WWW http://www.griphyn.orghttp://www.ppdg.net http://www.eu-datagrid.org © 2004 IBM Corporation

Horizontal Process Business Flexibility IT Simplification Partners Partners Partners On-Demand Operating Environment • IBM’s Articulation of Next-Gen Enterprise IT Environment Integration • Business Modeling • Process Transformation • Application & Information Integration • Access • Collaboration • Business Process Management Infrastructure Management • Automation/Virtualization • Availability • Security • Optimization • Provisioning • Policy-based Orchestration • Business Service Management • Resource Virtualization of Servers, Storage, Distributed Systems/Grid and the Network SOA Grid © 2004 IBM Corporation

  13. Web Services Evolution with SOA (Blank Page) © 2004 IBM Corporation

  14. UDDI Find Publish WSDL Service Bind Requestor SOAP What SOA (Service Oriented Architecture) is • SOA aims at realizing “plug-and-play” software component • Easy to connect and easy to disconnect • Consists of a collection of “services” and can communicate each other simply • A “service” is a function that is well-defined, self-contained, and does not depend on the context or state of other services. • Web Services as one of technology to realize • A set of architectural principles which address characteristics • Amazon and Google as early adopters © 2004 IBM Corporation

  15. Enterprise Service Bus Server Foundation Modeler Monitor BPEL Studio SOA Evolution • ESB as a design pattern for Services Orchestration • Total Application Lifecycle support for SOA • Transaction/Long Transaction needs © 2004 IBM Corporation
