Abstract :
Service-oriented architecture (SOA) is becoming an integral part of the IT landscape. An increasing number of organizations are building service-oriented architectures, all major application vendors have incorporated support for technologies related to SOA, and Web services are becoming an important mechanism for business-to-business transactions. The technology for realizing service-oriented architectures is maturing, making initial adoption easier. However, with larger deployments of Web services in organizations, new questions related to implementation strategies, governance approaches, and broader organizational impacts need to be considered.
