Design of Service Component Layer in SOA Reference Architecture

This paper introduces the design of a template of architectural building blocks (ABBs) for the service component layer in the SOA solution stack (S3) reference architecture. SOA solution architects can use the industry practice-based template as a starting point to quickly configure, customize, and prototype their application-specific service component layer that provides code containers that implement services. We then formalize the issue of service component implementation selection into a one-sided sealed English auction problem. Along with architectural decisions, a cost decision model is deduced to help solution practitioners in selecting proper service component providers for the most cost-effective design of service-oriented solution design.
