Agenda

• What is SOA and EDA/ESB?• Real-world Example• Best Practices• Introduction to BPEL and the Oracle BPEL

Process Manager• Demo!


What is SOA?

ERP/Legacy Apps

Custom Apps& Services

Web services

WSDL/WSIF

XML/XML Schema

SOAP JCA JMS

BUSINESS SERVICES

XSLT/XQuery

BPEL

ORCHESTRATE

Reduce friction, enhance visibility, thrive on change

What is EDA?

Devices RFID, Sensors

Network, Automated Call Distribution (ACD) Switches

Embedded systems

Security Authentication, authorization, audit trail

Database and Data Sources SQL, Legacy

Flat files, Excel, Logs

System Management Performance metrics, alerts, logs

System status – outages, utilization

Business Process Management Monitoring activity metrics, process

states

Messaging Systems JMS, TIBCO, MQSeries

Applications CRM, SCM, ERP, Financials

Web, External Business Partners

Business Events, Transactions

Important design concept, core to SOA• Supports dynamic business processes

• De-couples requestor from service provider (“Loose Coupling”)

• Fits asynchronous design patterns

• Business Activity Monitoring – Enables insight into distributed data


SOA/EDA InfrastructureInteraction Patterns

• Request/Reply• Requester to Provider and back

• Conversational• Coordinated exchange of messages

between two or more participants

• Notification/Response• One-way Notification to Provider,

Response from Provider to Requester

• Publish/Subscribe• Sender publishes to Topic, rather than

addressing to specific recipients

Example: DSL Provisioning at Belgacom

Application for the provisioning and activation of DSL lines. Belgacom is processing up to 15,000 DSL provisions / day through SOA and BPEL processes which link their customer interfaces and OSS layer, managing activation and repair.

Application Server


Best PracticeLoosely coupled interfaces (XML, WSDL) for coarse-grained services

Make composite apps easier to build and maintain, increased chance for re-use, easier to version

Asynchronous messaging(WS-Addressing)

Processing efficiency, reliability

Data-driven / rules-driven processing

More flexible applications, fewer production code changes

Separate process flow logic Management, monitoring, compliance

SOA standards Future-proof applications, vendor independence, decreased learning curve

Expect to focus on exception management

70-80% of time spent on negative cases. Build more robust composite apps.

Policy-driven security Ensure security compliance, enhanced management
