  4. Agenda • Why the need for service oriented architectures (SOA) • IT Challenges • What is SOA and Web services • Elements of SOA • Benefits of SOA • Business Opportunities in SOA • Oracle’s solution for SOA • Tools, Application Servers, Database, Portal, Integration • Customer case Studies of SOA • How to get started?

  5. IT Challenges • Applications are monolithic • Discrete steps supported by single application • Applications are brittle and are not easy to adapt • Applications are hardwired to presentation devices • Complexity of heterogeneous technology • Interactions within and across enterprises are difficult • Based on proprietary standards & technology - No Interoperability • Difficult to connect to a large number of applications • Applications operate as inflexible silos • Difficult to build end-to-end business processes • Difficult to adapt business processes

  6. The Answer… • Applications are monolithic • Build applications as services • Complexity of heterogeneous technology • Do not create “yet another platform” • Deploy on standards based platforms • Use interoperable technology • Applications operate as inflexible silos • Integrate services to event-driven business processes • Compose business processes rapidly and adapt to changing requirements

  8. Service Oriented Architecture (SOA) • “Service-oriented architecture is a style of multi-tier computing that helps organizations share logic and data among multiple applications and usage modes” • Web Services enable an interoperable SOA • Across programming languages • Across hardware and O/S platforms • Across computing platforms (J2EE, .NET)

  9. Service Registry Publish Find Web Services Conceptually ServiceRequestor ServiceProvider Invoke

  10. Points to description UDDI Registry Points to service Finds Service Web Services Technologies WSDL Describes Service Web Service Client (J2EE, .NET,PL/SQL …) Web Service (J2EE, PL/SQL,.NET,C/C++,Legacy …) SOAP Invokes with XML Messages

  11. Web Services Versus Web Applications Web Services Web Application • XML/SOAP • Program-to-program interaction • Static or dynamic integration • Re-usable service • HTML • User-to-program interaction • Static integration of components • Single use service

  12. Browsers HTML Web Presentation EJBs BusinessLogic SOAP Databases Firewall External Applications Application Server Benefits of SOA and Web Services • Application Re-Use • Enables sharing of business logic • Shields developers from mode-specific presentation

  13. Case Study: Dell • Dell Business Model • Direct material purchase represent 70% of revenue • Inventory asset exposure – prices drop 0.6% per week • Need effective supply chain planning • Dell’s challenges • Dell ships in 5 days, replenishes inventory in 45 days • Dell maintains an inventory that lasts about 30 hours • Manage large number of product transitions every year

  14. Business Opportunities: Dell • Dell’s Solution: Vendor managed hubs • Dell uses Web services based event management • Dell publishes a production schedule every 2 hours using web services • Vendors’ Inventory management systems determine what is needed for shipment • Vendors pick, pack, and ship in 90 minutes to Dell’s manufacturing units • Dell has no stock rooms now, 2 hours of inventory

  15. Oracle’s Web Services Strategy • Make Web services pervasive • Embed Web services across the infrastructure • Interoperate based on industry standards • Build Web services on J2EE and XML • Maximize productivity, minimize retraining • Inherit performance, reliability, security of OC4J • Deliver simple and business Web services • Enable business process based Web Services

  32. Where do I Start? • Look at existing technology investment and determine where Web services will add value • Look for low risk high benefit projects that do not disrupt existing operations • Focus on projects with short timelines and clear deliverables. • Develop deep understanding of the state of web services • Decide which standards are appropriate for your enterprise • Build out an entire Web services architecture
