Summary

• SMX versions
• Current state architecture and NMR features
• Short term SMX 4.4
• Middle term SMX 5

3
My Background

• Jean-Baptiste Onofré
• Software Architect at Talend
• ASF member
• PMC for Karaf and ServiceMix
• Committer for ACE, Camel, Kalumet

4
ServiceMix ?

• Apache ESB
• Reliable messaging
• Routing/messaging/EIP
• WS/REST
• WS-BPEL
• Production ready feature (provisioning, cluster,
  etc)

5
SMX 3 old stable

• Very popular in production
• Powered by Spring, and JBI oriented

ServiceMix JBI Components

SMX 4 current stable

• OSGi/Karaf powered
• NMR layer
• JBI backward compatible

Pro/Cons
ServiceMix 3 ServoceMix 4
Great adoption Very stable
Documentation - Poor documentation/website
- Only JBI and Spring OSGi/Karaf, highly extendable
- Production tooling/features Provisioning, failover, enterprise feature
8
Short term

• SMX JBI Components 2011.02 dependencies upgrade
  (ActiveMQ 5.5.0, Camel 2.8.3, CXF 2.5.0)
• SMX Specs 1.9.0
• SMX Utils 1.5.0
• SMX 3.4 last SMX3 release, just dependencies
  upgrade

9
Short term SMX 4.4

• Dependencies upgrade Karaf 2.2.4, ActiveMQ
  5.5.0, Camel 2.8.3, CXF 2.4.4
• Documentation/website
• Improvement on build and remove the JBI layer by
  default
• Focus on the NMR 1.5.0 features

10
Current NMR status

• NMR is a feature core bus of SMX4
• NMR is highly plug and play
• JBI is just a subset of the NMR

11
NMR security

• Users authentication
• Endpoint access authorization
• Exposed as OSGi services org.apache.servicemix.n
  mr.api.security.AuthenticationService
  org.apache.servicemix.nmr.api.security.Authorizati
  onService
• Configured as service properties endpoint,
  operation, type, roles, rank

12
NMR JNDI

• Provide a JNDI context factory
• Expose OSGi service as JNDI using
  osgiservices/ltinterfacesgt/filter
• InitialContext context new InitialContext()
• ExampleService (ExampleService)
  context.lookup("osgiservices/com.example.ExampleS
  ervice")

13
NMR Interceptors

• Intercept messages between NMR endpoints using
• NMR events (global)
• Wires (specific from/to)

14
NMR Events

• API receiving notifications
• EndpointListener
• public interface EndpointListener
• void endpointRegistered(InternalEndpoint
  endpoint)
• void endpointUnregistered(InternalEndpoint
  endpoint)
• ExchangeListener
• public interface ExchangeListener
• void exchangeSent(Exchange exchange)
• void exchangeDelivered(Exchange exchange)
• void exchangeFailed(Exchange exchange)
• Registration as OSGi services

15
NMR Audit

• File or JBDC auditor
• Store all exchanges including mep, status, role,
  properties, in (content and properties), out
  (content and properties), fault (content and
  properties)
• Shell commands to manipulate the audit log
• audit/find status error

16
SMX5, Karaf
Karaf 3 with profiles, OSGi subsystem,
etc Karaf Cellar cluster support (especially
around DOSGi) Karaf Cave as default
repository/registry Provide a complete pro
console (leveraging the new Karaf WebConsole
sub-project)
17
SMX5, from NMR to Camel

• Promote Camel as the premium solution for
  routing (replacement of the NMR)
• Refactor most interesting NMR features to be
  Camel oriented (audit, events, tracing, etc)
• Leverage Camel new features support of async
  transactions, unified statistics, improvement of
  the ThreadPoolProfile for thread management, etc

18
SMX5, CXF

• Leverage new CXF features
• Better OSGi/Karaf integration (new shell
  commands, etc), including config admin to
  configure CXF workqueues
• Better management capabilities
• Better performance especially around WS-Security
• Security STS, WS-Trust support, JAX-RS security
  (OAuth 2, SAML, etc)
• Update to WS-RM 1.1
• Update to use CXF WS-Notification
