  1. "SOA en BPEL" Is Service Orchestratie een overdraagbare aandoening? Sandor Nieuwenhuijs

  2. No Application is an Island Example: Modern Web Application Application for the provisioning and activation of cell phone plans Telco Activation Services SMS Activation Manager GPRS Activation Manager China Roaming Activation Manager Application Server Automatic Payment Approval New Plan Selection User Interface Service Not Available Exception ADF Orchestration Billing Services Payment Services Credit Card Payment Services

  3. Orchestration Today Not enough metadata  Not tool friendly Proprietary flow languages  Rare skill sets, consulting Hard Wired/Code  Rigid, difficult to change Incompatible Infrastructures  Difficult to manage and scale Java + JCA + JMS + EAI = “Not Enough” Java Services (EJB) Messaging Destinations (JMS) Legacy Applications (JCA, adapters) Portal Java Platform ? User Tasks Web Services (Sync and Async) ADF Orchestration

  10. What is BPEL? Markup language for composing a set of discrete services into an end-to-end process flow SalesDB start • 10+ years of R&D from MSFT and IBM • SOAP but also Java, JCA • Rich Flow Semantics • Optimized Bindings • XPATH+XSLT+XQuery • WS-Security • A Process is a Service Duplicate Number! Billing Router end
