The service-oriented approach enables programmatic collaboration to be realized while maintaining the autonomy of individual codes at the different institutes and organizations. In the current work a Genetic algorithm optimization logic implemented as a Grid service at Southampton is used to drive the design search process while the aerodynamic analysis code located in Singapore is used to evaluate the objective function of the design points. Experience gathered from the current study on airfoil shape optimization is valuable for establishing effective efficient and customised programmatic links between institutions to solve complicated engineering design problems. 1. Introduction Collaboration lies at the heart of Grid computing. 1 Grid computing provides the infrastructure and tools to encourage collaboration between departments institutions and research centres to deliver better research outcomes. The concepts of service-oriented computing are seeing wide acceptance and becoming a standard approach for tackling distributed heterogeneous computing problems. Web services Grid services are evolving fast and the proposed WSRF WS-Resources Framework 2 is seen as a joint effort between industry and academia and
