The Role of Service Granularity in a Successful SOA Realization A Case Study
Naveen Kulkarni, Vishal Dwivedi · 2008
This paper presents the case study of a leading US financial Institution International Financial and Brokerage Services (IFBS), which faced SOA realization issues while it followed an inappropriate SOA design strategy. While riding on the SOA hype wave, it implemented thousands of fine grained Web-services without paying much heed to issues like governance, and usage within its business processes. IFBSpsilas service portfolio comprises of a gamut of services which although on paper looked good, but presented a lot of challenges in their usage and maintenance. We address some of these issues in this paper and present our framework for SOA adoption (called INSOAP) which can be effective in a similar end- to-end SOA adoption exercise in an enterprise.
