3. SOA Mythology

4. Introduction to SOA
SOA is an architectural style for building software applications.
 Need for SOA
-- Heterogeneous IT infrastructures
-- Interfaces use different technologies, protocols and data formats.
 SOA Advantage :
-- Software Re-usability, loosely coupled , policy-driven
-- Service-based technology includes CORBA, SOAP , REST, SCA etc

5. Integration Frameworks and ESB
 Light weighted integration frameworks include Spring Integration and apache
camel and suited for simple integration needs.
 For complex integrations we need any one of the ESB's like Mule ESB , JBOSS
ESB or Apache Service Mix.
 All above Frameworks implements well know Enterprise Integration
Patterns (EIP)

6. BPM
 BPM enables Process centric thinking instead of functional thinking.
 Collaboration between business and IT to foster effective, agile and
transparent business processes [extract from BPM_For_Dummies - Kiran K,
VP-Software AG]
 Popular BPM includes IBM Process Manager, Oracle BPM Suite, TIBCO
Active Matrix, JBPM

7. Service Component Architecture aka SCA
 Architecture for building composite application following
SOA Principles.
 Similar to electrical components in Circuit board, Build
Service Component and wire them together to Composite
application using SCA.
 Components can be built in Java or any one of the programming languages
supported by SCA
 Created by major software vendors including IBM and Oracle and the
specification is maintained by Oasis Technical Committee.
 Open Source Implementations of SCA includes Switchyard, Fabric3m, Trentino
etc.

8. SCA Features
 Specification includes Component Implementation, Binding, Assembly and Policy
 SCA is Language Agnostic
 Supports diverse technologies , protocols and frameworks
 SCA is not JBI
 JBI (Java Business Integration) mostly addresses middle ware vendor requirement ,
eg : ( Service Interfaces for creating of new bindings )
 SCA is for Developers who want to built Composite applications

9. JBOSS Switch Yard
 Light weighted component based development framework
 Focused on building structured, maintainable services using the concepts and best
practices of SOA.
 Switchyard is set to replace JBoss ESB, adding better modeling and services
support.

10. Switch Yard Features
 Annotation over Configuration ( eg : Service dependency using @Service,
Dependency injection using @Inject )
 jBPM Components for Business Process Modelling
 Drools for Business Rule Processing
 Camel Components for Routing
 Supported bindings includes Http, SOAP, Rest (Rest Easy) , JCA, JPA, JMS,
AMQP etc (Bindings defines how one component communicates with other
another)

11. Switch Yard Demo
Getting Started :
 Patch EAP with downloaded switchyard zip (switchyard-1.1.0.Final-
EAP6.1.GA)
 Model your Services using Jboss Visual Tools
 Export Services to jar file and deploy the same in EAP
 Test the services via SOAP/UI or Maven Test
 Development Environment:
 Eclipse with Jboss Tools Plug-in / Jboss Developer Studio
 Java 6 or above
 JBoss EAP 6.0.1 integrated with Switchyard Module
 SOAP UI / Maven
