Abstract

Complexity is defined as the degree to which a software system is difficult to understand, maintain and evolve. The main difficulty stems from complex interaction patterns between system components/services. A growing importance of event-driven processing in service systems generates new research questions related to architectural styles that can best harness complexity when traditional service invocations/compositions are intermixed with event-driven publish-subscribe processing. This keynote addresses relevant complexity issues and offers a method to monitor and minimize software dependencies from architectural models.
