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.

Shape = Transport protocol

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
an esb gives soa its full value

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

how do we connect applications
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,

websphere message broker constructs flows and nodes
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

<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>

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.
what are message flows
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.
message flow example

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

message flow scenario

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.

nodes
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

Message Broker Parsers
a typical parser example
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.

message transformation
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
examples of message addressing

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”); ...

}}
