JBoss SOA Platform Strategy
Bring an SOA integration and process platform to mass market in an easy to consume and affordable package
Build core platform from existing components
Customers/Community –Registry, repository, JMS transport, and EJB endpoints
JBoss Enterprise Middleware –e.g., microcontainer, Messaging, JBossWS, Seam
Other OSS projects –e.g., Smooks for transformation
Extend to a Business Process Platform
Leverage jBPM and Rules mass adopted run time engines
SCA (Service Component Architecture)
Leverage Eclipse for visual designer and plug-ins –SOA lifecycle tools
Open up opportunities for Integration and SOA partners
Connectors, B2B Gateways, SOA Governance, Business Services

Enterprise Service Bus
JBoss Application Server
JBossESB Aims
SOA principles first and foremost
Use SOA principles internally as well as externally
Everything is (conceptually) be considered as a service
Every service can be replaced
Standards compliant
