SOA Integration - 4 Implementation Scenarios

Having understood the structure of the blueprint covered in Chapter 3, Integration Architecture Blueprint, this chapter will use individual scenarios to illustrate how the business pattern can be implemented using the Integration Architecture Blueprint.

The scenarios shown in this chapter have been deliberately designed to be independent of specific vendor products, and are based solely on the building blocks that form part of the different layers of the blueprint.

The symbols used have the same semantic meaning as described in Chapter 3.

This chapter will:

• Explain service-oriented integration scenarios
  .
• Use scenarios to show how data integration business patterns can be implemented
  .
• Present a description of scenarios for implementing the business patterns for EAI/EII integration
  .
• Look in detail at the implementation of event processing business patterns
  .
• Describe a scenario for implementing business patterns for grid computing and Extreme Transaction Processing (XTP)
  .
• Explain how an SAP ERP system can be combined with the integration blueprint
  .
• Explain how an existing integration solution can be modernized using SOA, and describe a scenario that has already been implemented in practice
  .
• Combine the integration blueprint with the other Trivadis Architecture Blueprints

Service-oriented integration scenarios

These scenarios show how the service-oriented integration business patterns described in Chapter 1 can be implemented. These business patterns are as follows:

• Process integration: The process integration pattern extends the 1: N topology of the broker pattern. It simplifies the serial execution of business services, which are provided by the target applications.
  .
• Workflow integration: The workflow integration pattern is a variant of the serial process pattern. It extends the capability of simple serial process orchestration to include support for user interaction in the execution of individual process steps.
