JBossESB. SOA everywhere!

1 JBossESB SOA everywhere! JBoss Inc. 2005

2 Aims To provide the standard OSS infrastructure for SOA SOA principles first and foremost Use SOA principles internally as well as externally Everything will (conceptually) be considered as a service Everything will be replaceable Standards compliant Though requirements live longer 2 The Professional Open Source Company

3 JBossESB = SOA Infrastructure 3 The Professional Open Source Company

4 JBossESB will provide Process orchestration Protocol translation Adapters Repositories (e.g., UDDI) Change management (hot deployment, versioning, lifecycle management) Quality of service (transactions, failover) Qualify of protection (message encryption, security) Management (versioning of services) 4 The Professional Open Source Company

5 Architecture overview 5 The Professional Open Source Company

6 Requirements Cannot mandate specific capability implementations All capabilities accessed as services Plug-and-play Extensibility All capabilities are message based Including (conceptually) the container Standards are important JBI Perhaps SCA 6 The Professional Open Source Company

7 JBossESB and standards 7 The Professional Open Source Company

8 Core message Everything is a service, including the bus All services are interacted with via messages. Includes service lifecycles Containers abstracted within architecture Services plugged directly into a lifecycle bus Services can be plugged into multiple buses concurrently 8 The Professional Open Source Company

9 The SOA Bus Underlying the ESB is a MOM abstraction Does not mandate implementation JMS, SOAP etc. ESB must be able to support pure-play Web Services deployments WS-RX Capabilities can be provided by multiple implementations Concurrently Support multiple buses Single bus concept is wrong Counter to SOA and Web Services Biggest problem with old-style EAI 9 The Professional Open Source Company

10 ESB versus SOA versus EDA SOA rules take precedence EDA is a way of implementing SOA JBossESB is a unitary EDA ESB is a narrowing of SOA Mediation not necessary for SOA Routing not necessary for SOA SOA infrastructure first and foremost ESB veneer 10 The Professional Open Source Company

11 Message view 11 The Professional Open Source Company

12 Core service requirements Container JBoss Microcontainer default MOM JBoss Messaging and Web Services Transformations JBoss Rules Repository UDDI Basic contract definition QoS Service versions 12 The Professional Open Source Company

13 Standards Important for interoperability Web Services JMS Important for portability JBI SCA But Requirements are more important Standards change! 13 The Professional Open Source Company

14 JBossESB interfaces 14 The Professional Open Source Company

15 Addressing Logical and physical names Logical requires indirection to lookup WS-Addressing based Not dependant on Web Services Just capabilities 15 The Professional Open Source Company

16 The Message Two levels of message Seen and used by clients and services Seen and used by the core ESB Latter is a superset of the former interface Message { public Header getheader (); public Context getcontext (); public Body getbody (); public Fault getfault (); public Attachment getattachment (); } 16 The Professional Open Source Company

17 Client plugin interface ClientPlugin { public void send (Address to, Body msg); public void sendasync (Address to, Body msg); public void sendasync (Address to, Body msg, Callback cb); public void sendreliable (Address to, Body msg); } interface ClientPluginFactory { public ClientPlugin getplugin (ContractDefinition def); } 17 The Professional Open Source Company

18 Service plugin interface ServicePlugin { public Body receive (Address from); } interface ServicePluginFactory { public ServicePlugin getplugin (ContractDefinition def); } 18 The Professional Open Source Company

19 But Lots to do We have many components We need to collaborate with partners SOA-within-and-without should help Best-of-breed approaches to ESB deployments No single solution Talking to partners and vendors now JBossESB as the unifying infrastructure 19 The Professional Open Source Company
