| Abstract: |
In developing Service Oriented Architecture strategy, a primary concern is how to protect existing application investments while enabling real improvements in adaptability. An increasingly popular approach is to deliver new functionality that reuses services from many existing applications and sources, so called Composite Applications. But not surprisingly there are many issues with this inherently compromise architectural pattern and in this report we will look at the architectural options, discuss the many issues and look at how some users have overcome these. |
| Backgrounder: |
Composite Applications support new business processes by bringing together and reusing functionality from several existing applications. Reading much of the analysis and comment in this area we might easily conclude that composite applications are the new silver bullet. In fact a composite application approach is an inherent part of the Service Oriented Architecture.
CBDI has been advising for some time that the essential place for an enterprise to commence its SOA activity is in exposing core services from existing applications. We advise that these services need to be normalized such that they have minimal dependency upon the underlying application, which will make subsequent integration as simple as possible.
