Multiple Choice

Below are excerpts from four different SOA adoption strategy documents. Based on your understanding of SOA, service-orientation, and the goals of service-oriented computing, select the adoption strategy that is clearly the most likely to succeed:

• A) "As part of our planned transition toward service-orientation, we will continue to extend the existing legacy applications with transformation-centric middleware that will enable seamless integration and runtime conversion between the different data models and data formats used by these applications."
• B) "Each of our existing legacy applications already establishes a domain boundary that is defined by the purpose of the application. We are confident that by leveraging these pre-defined silo-based boundaries we can create a series of effective domain service inventories, each with a scope that corresponds to a legacy application boundary."
• C) "Our strategy fully supports the tactical (short-term) nature of service-oriented computing by de-emphasizing standardization and allowing different project teams to deliver services optimized to their respective requirements. This not only speeds the initial delivery of services, it further supports interoperability by enabling services to leverage established integration technologies."
• D) "Our strategy is to make the consistent application of service-orientation principles a priority in order to support the attainment of the goals of service-oriented computing. The primary justification for this approach is the fact that we have identified the goals of service-oriented computing to be in alignment with our own business goals."
