  • 1. Next Generation Open Source SOA Burr Sutter Sr. Product Manager, SOA (JBossESB, Riftsaw, jBPM, Drools) September 3, 2009 1 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)
  • 2. Agenda Is SOA Dead? JBoss SOA Platform Overview & Roadmap RESTful inclinations Complex Event Processing (CEP) w/ Drools Fusion Infinispan + ESB BPEL 2 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)
  • 3. Is SOA Dead? "The report of my death was an exaggeration." Mark Twain 3 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)
  • 4. SOA, ROA & WOA – Oh My! ROA – Resource Oriented Architecture - REST (Representational State Transfer – Roy Fielding) WOA – “Web Oriented Architecture (WOA) is a style of software architecture that extends service-oriented architecture (SOA) to web based applications, and is sometimes considered to be a light-weight version of SOA. WOA is also aimed at maximizing the browser and server interactions by use of technologies such as REST and POX.” - Wikipedia SOA is NOT SOAP - architectural style vs wire protocol SOA is NOT WS-* - patterns & principles vs a large body of standards 4 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)
  • 5. SOAP vs REST Technical Differences HTTP Verbs: SOAP – POST REST – GET, PUT, POST, DELETE Contract Definition: SOAP – WSDL – operations & messages REST – HTTP Verbs are the operations, messages may or may not have a contract via XSD and/or JSON (POX – plain 'ol XML) Content-Type: SOAP – focused on XML REST – allows for any payload – XML, JSON, Atom, RSS, etc. Clients: SOAP – requires a client that understands WSDL REST – requires a client that understand HTTP 5 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)
  • 6. Forget Services, I want Events! - EDA EDA – “Event Driven Architecture is a software architecture pattern promoting the production, detection, consumption of, and reaction to events. An event can be defined as a significant change in state” - Wikipedia Services have historically been more request-response focused – synchronous processing – normally for responding to awaiting users/consumers. Events are more real-time alerting, no waiting – asynchronous processing – think push. “Event-driven architecture can complement service-oriented architecture (SOA) because services can be activated by triggers fired on incoming events” - Wikipedia. 6 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)

  • 12. REST 12 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)
  • 13. Value of REST with an ESB JBossESB is not hard-wired into Web Services nor JMS, it is async event-driven and also allows for sync request- response. RESTful style interactions (GET, PUT, POST, DELETE) allow for Groovy, JavaScript, Ruby, etc clients to more easily consume a service. JBossESB now allows for different content types and use of HTTP response codes. REST is based on HTTP – new http-provider (ESB 4.7) 13 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)
  • 14. New HTTP Provider (jboss-esb.xml) <providers> <http-provider name="http"> <http-bus busid="http_gateway"/> <exception mappingsFile="/http-exception- mappings.properties" /> </http-provider> </providers> <services> <service category="Sales" name="List" description="" invmScope="GLOBAL"> <listeners> <http-gateway name="sales" busidref="http_gateway" urlPattern="sales/*" /> </listeners> <actions mep="RequestResponse"> <action name="createAtomFeed" class="atom_publisher.MyAction"/> </actions> </service> http://localhost:8080/MyESBArchive/http/sales/* </services> 14 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)

  • 18. ESP + CEP via ESB, Rules & JON Many Streams Or Flows ESB: consumption, capture, transformation, routing, orchestration Rules: selection, aggregation, correlation, generation and publication Governance Tools Repository: for editing, versioning, testing JON: start/stop services, monitor and alert on service and publishing new rules and SOA and action-level performance, monitor and alert on artifacts business metric values 18 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)
  • 19. Event Declaration & Selection declare StockTick @role( event ) @expires( 2m ) end rule "average over last minute" when $stat : Statistics( $symbol : symbol ) Number( $av : doubleValue ) from accumulate( StockTick( symbol == $symbol, $p : price ) over window:time( 1m ) from entry-point average( $p ) ) then modify( $stat ) { average = $av } end 19 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)

  • 21. Value of CEP – Drools Fusion Stateful Rules Engines live in ESB Nodes, they retain the real-time history of the event flow Rules look for significant/interesting events in the stream, expiring older, insignificant events (memory management) – stateless rules engines/ESB nodes can route to stateful engines. Event data can be aggregated/accumulated over a time window or event series New events or messages back through the ESB can be generated, providing an alerting mechanism. 21 JBoss World 2009 | Burr Sutter (bsutter@redhat.com)
