2.5 Summary

   

This chapter covered the following issues:

  • A number of drivers contribute to the need for a broad-scale, general-purpose integration infrastructure.

  • The accidental architecture is the dominant design in use today. In this kind of system, the enterprise is currently not very connected at all.

    • Only 10% of applications are linked.

    • Of these, only 15% use any kind of middleware.

    • To date, distributed computing technologies have perpetuated, not solved, the accidental architecture problem.

  • Hub-and-spoke EAI brokers have had moderate success. However, they:

    • Are largely proprietary

    • Failed to provide organizations with a standardized integration platform that could be applied to general-purpose use across an enterprise

  • The ESB draws value from lessons learned in EAI broker technology.

  • Integration is a departmental and corporate culture issue as much as it is a technical issue.

  • The ESB allows incremental adoption to occur in accordance with the individual needs of departmental development schedules.
