Abstract:
The critical business requirements and compelling nature of the competitive landscape are pushing Information Technology systems away from the traditional centrally controlled corporate-wide architectures towards dynamic, loosely coupled, self-defining and service-based solutions. Web services are regarded as a key technology for addressing the need for connecting extended applications and providing standards and flexibility for enterprise legacy systems integration. This paper reports our experiences when integrating a financial market trading system. This integration process starts from analysing the trading system’s architecture, then identifying system functionality and finally realising the design and implementation of a Web service. Performance and security and the trade-offs involved are the major focus points throughout this process. Comprehensive benchmarking is conducted with and without Web service and security considerations.
