Abstract

Service-Oriented Architecture (SOA) is an emerging paradigm that entails building applications as a collection of flexible services. Although there is a considerable amount of research on the challenges involving the transition to SOA, it is still necessary to incorporate frameworks that provide guidance for companies adopting this architecture. Accordingly, this article presents a framework, which is entitled OSTRA (Opportunity-driven Service-oriented TRAnsition). OSTRA provides a realistic approach for the development of SOA by considering short-term and long-term term goals as well as by balancing planning and management. This work describes the three streams that OSTRA organizes throughout the SOA transition: SOA roadmap, SOA development and SOA governance. Moreover, it discusses the implementation of OSTRA in a real organization.
