Abstract:

When managing very large highly integrated information systems, special attention needs to be paid to the interfaces among the large components of the system. Only if they are stable and abstract enough, the components can be evolved independently. In practice, this is often implemented as a "Service Oriented Architecture (SOA)".

 Credit Suisse has been active in the field of service oriented architecture over many years. I chose the birth date of the "Credit Suisse Information Bus" 13 years ago as the starting point of a long journey towards an enterprise SOA at Credit Suisse. I have chosen a number of case studies, marking major steps in the SOA progress. Each case study starts with a strategic business need, continues with the chosen solution, and concludes with a discussion of the achievements and the remaining gaps. Putting these case studies into a historic perspective, shows a continuous evolution, where each step expands the business value, closes gaps of previous solutions, and last but not least leads to new challenges. I will illustrate each case study with examples and data.
