5 What is Service Oriented Architecture (SOA) ?

6 Agenda Distributed Computing Service Oriented Architecture (SOA) Service Delivery Platform Benefits Oracle Fusion Middleware

7 Phase I Downsize Client/Server Client/Server DCE DCE Phase II Phase IIComponents CORBA CORBA DCOM DCOM EJB EJB Phase III Phase IIIMessaging MOM MOM History of Distributed Computing

8 Issues with Existing Models Proprietary protocols Interoperability Platform lock-in Inflexible

9 What is SOA ? Evolution of distributed computing Application functions are modularized and presented as services IT architecture for synchronous and asynchronous applications Services are loosely coupled Service interface is independent of the implementation

10 Why SOA ? – The Cruel Reality Source: Gartner

11 Why SOA ? - The Reality of Modern Business Geographic, Departmental Evolution Mergers & Acquisitions (M & A) Compliance issues Difficult to Answer Simple Questions Costly to Operate Inflexible Difficult to achieve benefits of an Information-Driven Enterprise E-Business Suite Siebel Legacy SAP Web Services Suppliers PeopleSoft Business Intelligence

12 Why SOA : Monolithic Applications Inflexible, Inefficient, Hard to Maintain Print Invoices Print Invoices Generate POs Generate POs Credit Verification 1 Credit Verification 1 User Authentication 1 User Authentication 1 Account Validation 1 Account Validation 1 Create Customers Create Customers Credit Verification 2 Credit Verification 2 User Authentication 2 User Authentication 2 Account Validation 2 Account Validation 2 Hard to adapt to changing business requirements Duplication of functionality means wasted resources Small fixes require large investments of time and labor

28 Policy Enforcement and Visibility: Monitoring Provide real-time visibility into Web Service interactions Automatic issue resolution by dynamic policy updates Alerts about anomalies Enforce policies Validate compliance with IT best practices

29 Benefits of SOA Better reuse Build new client functionality on top of existing Business Services Well defined interfaces Make changes without affecting clients Easier to maintain Changes/Versions are not all-or-nothing Better flexibility
