Abstract

Large-scale distributed applications tend to become more and more complex and hard to develop, and execute. Approaches used when building such systems have to be revised, in order to decrease coupling within the code and increase productivity during the development process. Especially event-based programming applied to Web services should gain much attention. In this paper, we present an experimental publish/subscribe infrastructure, which introduces robust event-based mechanisms to be used with Web services-enabled applications. The concept of this solution is built upon the extensibility and configurability principles. We show that performance gap between traditional distributed event-based technologies and the Web also services-based approach is not necessarily as significant as most people tend to think.
