Enterprise Systems Integration

  1. 1. Enterprise Systems IntegrationLong way to SOAAdastra klubVít Kotačka19. 6. 2012© Adastra Group
  2. 2. Agenda  Levels of Integration Maturity  Architectural solutions  Technical solutions  Projects & practice2
  3. 3. Enterprise Integration  Enterprise integration is the task of making disparate applications work together to produce a unified set of functionality.3
  4. 4. Levels of Integration Maturity4
  5. 5. Point-to-point integration  Easy & quick deal  Easy & quick implementation  Usually cheap cmp Streight Integration easy expose data Sytem A System B request data5
  6. 6. Point-to-point integration problems  Geometric progression complexity  Different formats and protocols  Transitive dependencies cmp Streight Integration difficult expose data for A Sytem A System B request data from B request data request data from C from x expose data expose data for A for B expose data for C System C System x request data from x6
  7. 7. Integration tier  Central control over data flow  Unified message format  Set of protocols (company communication standard)  Services reuse  Central data transformation, orchestration etc. cmp Middlew are expose data expose data MiddleWare Producer 1 Consumer A request data request data expose data expose data Producer 2 Consumer B request data request data7
  8. 8. Integration tier problems  Higher costs  System complexity increasing  Slow (implementation/management) reaction cmp Middlew are expose data expose data MiddleWare Producer 1 Consumer A request data request data expose data expose data Producer 2 Consumer B request data request data8

  13. 13. Main Integration Styles  File Transfer – each application produce files of shared data for others to consume and consume files that others have produced.  Shared Database – applications store the data they wish to share in a common database.  Remote Procedure Invocation – each application expose some of its procedures so that they can be invoked remotedly, and have applications invoke those to initiate behavior and exchange data.  Messaging – each application connect to a common messaging system, and exchange data and invoke behavior using messages.13
  14. 14. Two main architectural solutions  Messaging + Broker  BPM based engine ̶ BPEL engine ̶ BPMN engine ̶ Rule engine ̶ Workflow engine14
  15. 15. Message Broker15

  19. 19. Canonical Data Model  A common model independent from any specific application. Require each application to produce and consume messages in this common format.19
  20. 20. Technical solutions20
  21. 21. Messaging & BPM Solutions  IBM WebSphere MQ  Oracle SOA Suite  IBM WebSphere Message Broker  Apache ActiveMQ  Drools  Apache Camel21
