  2. Agenda • ESB Market Dynamics • What is an ESB? • What is Message Broker? • Message Broker Constructs • Product Architecture • What’s new in 6.1 • Roadmap

  3. The Connectivity Challenge … to run their business like this. Customers want to improve this…. Why? Reduce Complexity Manage Exponential Change Ensure Compliance Reduce Cost Improve Control

  4. 100% 50% 76% 76% New projects Maintenance & operation of existing applications IT Spending Dilemma Customers want to allocate more money for new projects 100% New projects 50% Maintenance & operation of existing applications Time Time

  5. SOA turns this… …into this. Application Application Application Application Service Service Interface Interface Interface Interface Interface Interface Interface Application Application Application Application Service Service Service Service Service Service interface = SOA: • Introduces rich business abstractions to describe the application interface. • Decouples the interfaces from the business applications. • Reduces the number and technical complexity of interfaces. • Enables re-use of both the business applications and their interfaces. SOA simplifies connectivity interfaces… …but you still need to know (1) what services you can connect to, (2) where they are, (3) how to connect to them, (4) how to log into them, (5) how to mediate the differences in data between them.

  7. Shape = Transport protocol Color = Data format What is an Enterprise Service Bus? An Enterprise Service Bus (ESB) is a flexible connectivity infrastructure for integrating applications and services. An ESB performs the following between requestor and service • MATCHES & ROUTEScommunications between services • CONVERTSbetween different transport protocols • TRANSFORMSbetween different data formats • IDENTIFIES & DISTRIBUTESbusiness events

  8. Service Service Service Service Interface Interface Interface Interface Interface Service Service Service Service Service Service Service Service Service Service The ESB: • Connects and signs you into the appropriate service without requiring a hardcoded connection. • Communicates using the right protocol. • Customizes communications so that the message to the receiver makes sense. • Logs and manages the interaction and correlates events. An ESB gives SOA its full value An ESB turns this… …into this. Interface Interface Enterprise Service Bus Enterprise Service Bus Service Service The ESB  Virtualizes access to services.

  12. Agenda • ESB Market Dynamics • What is an ESB? • What is Message Broker? • Message Broker Constructs • Product Architecture • What’s new in 6.1 • Roadmap

  13. How Do we Connect Applications? Protocols • Applications need to talk with each other over a communications protocol. • e.g. MQ, TCP/IP, HTTP, File system, FTP, SMTP etc. Message Formats Applications need to exchange data, with specific formats e.g. Binary (C/COBOL), XML, Industry (SWIFT, EDI, HL7), User-defined Mediation Patterns Mediation patterns allow applications to interoperate. e.g. Route, Transform, Enrich, Filter, Monitor, Distribute,

  14. WebSphere Message Broker – Protocols and Applications Industry and Vendor Protocols IBM Protocols Any 3rd-party JMS (TIBCO EMS, Sonic MQ, BEA JMS, webMethods, See Beyond, Vitria) WebSphere MQ (+ PM4Data) (Enterprise applications (+ managed file transfer)) WebSphere MQ Everyplace (Mobile device applications) TIBCO Rendezvous (plug-in component) WebSphere MQ Telemetry (RFID, sensors & actuators) HTTP and HTTP(S) FTP and File WebSphere MQ Real-time (Very low latency over WANs, and the Internet) TCP/IP Sockets WebSphere MQ Multicast (Reliable Multicast Messaging (RMM)) (Very low latency for LANs) SMTP CICS Custom JDEdwards SAP Siebel Oracle Peoplesoft Enterprise Applications

  15. WebSphere Message Broker Constructs – Flows and Nodes • . • Message Flows • Provides the processing sequence required • to connect applications together Nodes Performs a different (input, output or processing) action

  16. <order> <name> <first>John</first> <last>Smith</last> </name> <item>Graphics Card</item> <quantity>32</quantity> <price>200</price> <date>07/11/08</date></order> [Customer, Order, Quantity, Price, Date] WebSphere Message Broker Constructs - Mediation Patterns Mr. Smith, Graphics Card, 32, 100, 11/07/08 [Customer, Order, Quantity, Price, Date] • An Application Integration Scenario. • Application A sends some data to application B with agreed format (UK currency) • Application C is introduced. It needs the same data, but needs data in different format (US currency and XML) • So, we now have an integration choice to make. Either application C must be enhanced to support the data format between A and B, or application A must be enhanced to support application C's data format.

  17. What are Message Flows? • Message flows are transactional • Provides vital processing and data manipulation • Completes all or none of its processing successfully. • Message flows are multithreaded • Message passing through a series of nodes will execute on a single thread. To allow • message flows can be defined with many additional threads assigned to them to increased message throughput. • Peak workloads use additional threads, which are pooled during inactivity. • Message flow nesting and chaining allow construction of enhanced capabilities. • Sophisticated flows can be rapidly constructed by linking individual flows together as well as nesting flows within each other.

  18. Output target (Failure) Message Flow Example Input source Output target A message flow contains the set of operations required to take a message from an originating application and deliver copies of it, some possibly transformed, to any number of connected applications for processing. Transform Output target

  19. Message is routed to the ‘Generate batch file’ node, which formats the message for subsequent output to a file in the ‘Write file’ node. Message Flow Scenario Routing decision is made based on a field described in the incoming message Message is transformed that is recognizable by the web service which is invoked by the subsequent ‘Call WS’ node.

  20. Nodes • The building blocks of message flows • Each node type performs a different (input, output or processing) action • Many different node types • Grouped into logical categories in the message flow editor

  21. Node Types • Input • Output • Processing • Protocol-specific • Transformation • Logical construct Examples: HTTP Input JMS Output Database Insert MQ Get XML Transform Try Catch

  22. Message Node Components output connectors node input connector Action input terminal input message tree output terminals output message trees • Nodes represent functional routines encapsulating integration logic • Terminals represent the various outcomes possible from node processing • Connectors join the various nodes through their terminals

  23. Model Input Message Bit-stream Input Message Bit-stream Parser converts logical structure to bit-stream F r e d S m i t h , G r a p h i c s C a r d … Parser converts bit-stream to logical structure < o r d e r > < n a m e > M r . S m i t h < / n … Model Output Message Bit-stream Output Message Bit-stream Message Broker Parsers

  24. A Typical Parser Example • Harry was the “parser” – he took the physical representation of the London Underground and converted into a logical structure. This logical structure is very much easier to work with. Into this Message Broker uses logical structures to describe physical data for similar reasons: it makes them much easier to work with, particularly when addressing or converting between data elements.

  25. Order Name Item Qty Price Date Integer String Date Integer First Last String String Message Modeling in Message Broker Physical Logical <order> <name> <first>John</first> <last>Smith</last> </name> <item>Graphics Card</item> <quantity>32</quantity> <price>200</price> <date>07/11/08</date></order> XML CSV John,Smith,Graphics Card,32,200,07/11/08 Same logical tree regardless of formats making it easy to add new formats Custom John Smith............Graphics Card.........3220020071108.........

  26. C Header XML Schema DTD COBOL Copybook WSDL WebSphere Transformation Extender Pre-built Enterprise Information System SOAP, MIME, CSV, IDOC, SWIFT, EDIFACT, X12, FIX, HL7, etc Define your own using the Eclipse-based Tooling (SAP, Siebel, PeopleSoft) File Import Type tree Different options for creating Message Models Message Set Parsers Message Broker

  27. Message Transformation • The conversion of one message format into another • Graphical, easy to use • Drag and Drop fields, apply functions • Convert XML to anything • Uses standard XSL Style sheets • Describe powerful transformations quickly • Uses SQL-based language (ESQL) • Uses Java programming language • Ability to use XPath • Run a WebSphere Transformation Extender map

  28. IF Body.Order.Date < ‘2008/01/01’ THEN INSERT INTO Database.OldOrders (LastName,Item,Quantity) VALUES (Body.Order.Name.Last, Body.Order.Item, Body.Order.Quantity);ENDIF; Examples of Message Addressing public class jcn extends MbJavaComputeNode { public void evaluate(MbMessageAssembly assembly) throws MbException { ... String lastName = (String)assembly.getMessage().evaluateXPath(“/Body/Order/Name/Last”); ... }}
