Dynamic monitoring of composed services

Abstract

Service-Oriented Architectures (SOAs) are becoming a dominant paradigm for the integration of heterogeneous systems. However, SOA-based applications are highly dynamic and liable to change significantly at runtime. This justifies the need for monitoring composed services throughout the lifetime of the service execution. In this chapter we present a novel approach to monitor services at runtime and to ensure that services behave as they have promised. Services are defined as BPMN (Business Process Modelling Notation) processes which can then be monitored during execution.
