2.4 Application patterns for Application Integration

Using the interaction classification framework introduced in this chapter in Figure 2-11 as a guide, we observe the following four Application patterns and their variations for Process-focused Application Integration (also known as intra-enterprise integration):

• Direct Connection Application pattern and its Message/Call Connection variations

  Allows a single interaction from the source application to be adapted and transported to one target application

• Broker Application pattern and its Router variation

  Allows a single interaction from the source application to be switched, split, and joined to multiple target applications concurrently

• Serial Process Application pattern and its Serial Workflow variation

  Allows a single interaction from the source application to execute a series of interactions with multiple target applications

• Parallel Process Application pattern and its Parallel Workflow variation

  Allows a single interaction from the source application to concurrently execute multiple series of interactions with multiple target applications

These four Application patterns for Application Integration are summarized in Figure 2-12. One dimension shows support for concurrent interactions to multiple target applications in parallel. The other dimension shows support for non-concurrent interactions to multiple targets in series.
