1 Next Generation JBoss ESB Presenter Kevin Conner Project Lead, JBoss ESB, Red Hat 3 rd September

2 Aims of the presentation Current and Future Highlight current issues (most can be worked around) Describe the approach in the next version Invite feedback 2

3 Topics Routing Registry Services Messages Service Contracts Gateways Service Models 3

4 Topics Domains Long Running Transactions Message Enhancements Choreography Monitoring Important Dates 4

5 Overview 5

6 Routing 6

7 Current Routing Example 7

8 Current Issues Physical Endpoint References Transported across ESB instances Visibility of Endpoint Firewalls Network routing Available client? Transient Failure Intensive Resource Usage 8

9 Routing in the next version 9

10 Routing in the next version Logical Endpoint References Local invocations through InVM (In memory, HornetQ Logging, Infinispan) Remote invocations through bridges (already established, bi-directional) Routing layer decides (services weighted) More Resilient Controlled Resource Usage 10

11 Convoluted routing in the next version 11

12 Registry 12

13 Current Issues Single, shared registry Possible federation using interceptors Does UDDI v3 solve this? 13

14 What's Missing? Are registered Endpoints still valid? Weighting for routing? Throttling? 14

15 Registry in the next version Local Service Registry (in memory, uddi, clustered) Endpoint Status updated by Bridging Events Weighting updated by Bridging Events Service information now consistent 15

16 Services 16

17 Current Issues Tied to transports (includes InVM) Most services pull messages No versioning support (can be done with content based routing) No Service Repository 17

18 Services in the next version No longer tied to transport Gateways handle external interaction Messages pushed into Service Versioned Services Service Repository 18

19 Messages 19

20 Current Issues Everything in a message Header Context Body Attachments Properties Reuse of message Java Object Serialization 20

21 Messages in the next version Just main body and attachments Separate message context Entries scoped (invocation, domain, conversation, permanent) Keep small XML Serialization on the wire Java within composite services 21

22 Service Contracts 22

23 Current Issues No global service contract Partial support through EBWS <actions inxsd= in.xsd outxsd= out.xsd faultxsd= fault.xsd,... >... </actions> 23

24 Service Contract in the next version Based on WSDL Enable automatic transformations Enable automatic exposure 24

25 Gateways 25

26 Current Issues Mostly One Way (in-only) Except JBR, EBWS, HTTP and *File (in-out) Notifiers No standard correlation mechanism 26

27 Gateways in the next version Bidirectional Publish ESB Service Endpoint Support for correlation Support for asynchronous Request/Response Support in-only/in-out/out-only/out-in Multiplexed Endpoint Publishing 27

28 Service Models 28

29 Service Models Webbeans POJO EJB Scripting Composite Services SCA 29

30 Domains 30

31 Domains 31

32 Domains Apply policies to Services Security Constraints Concurrency Constraints Policy Based Routing Transactional Requirements 32

33 Long Running Transactions 33

34 Long Running Transactions Based on WS-AT & WS-BA (not webservices) WS-AtomicTransaction Atomic Transactions Enlist local transaction in AT transaction All commit or rollback 34

35 Long Running Transactions WS-BusinessActivity Compensation based, requires business logic Work committed in units Effects undone by new operation 35

36 Message Enhancements 36

37 Message Enhancements Large Message Streaming Attachment Claim Check Message Expiry Message Coalescing Message Sequencing and In Order Execution 37

38 Choreography 38

39 Choreography Tighter BPEL integration jbpm 4 Drools Flow 39

40 Monitoring 40

41 Monitoring Wiretap Ping Traceroute Message Route Recording Platform Event Logging Business Activity Monitoring (based on events) 41

42 Important Dates 42

43 Important Dates 31 st March 2010 First Milestone Release 30 th June 2010 Second Milestone Release 30 th September 2010 Third Milestone Release. 30 th November 2010 GA Release 43
