2.5 Application patterns for Extended Enterprise

Using the interaction classification framework introduced in this chapter in Figure 2-11 as a guide, we observe the following three Application patterns and their variations for the Extended Enterprise business pattern (also known as inter-enterprise integration):

  • Exposed Direct Connection application pattern and its Exposed Message/Call Connection variations

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

  • Exposed Broker application pattern and its Exposed Router variation

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

  • Exposed Serial Process application pattern and its Exposed Serial Workflow variation

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

Each of the Extended Enterprise pattern names are prefixed with Exposed to highlight that these patterns are concerned with exposing applications outside of the enterprise boundaries.

These three Application patterns for Extended Enterprise are summarized in Figure 2-13. 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. Here the top right-hand corner has been left blank to indicate that Parallel Process implementations are currently not widely implemented in Extended Enterprise scenarios. As the process composition technologies mature, we expect to see more widespread use of the Exposed Parallel Process application pattern and its Exposed Parallel Workflow variation.
