Abstract:
Service-oriented architectures has become a commonly accepted solution for integrating enterprise applications around the globe. As the SOA environment grows, its complexity and the complexity of modelling, configuring and applying quality of service attributes to it increases. Though there are some tools supporting these activities, they are either limited to certain quality of service domains or dependent to specific development environments. In this paper, we elaborate a concept for managing quality of service attributes for Web services. In particular, our approach covers the modelling of arbitrary quality attributes based on a meta-model for quality attributes. It also covers the generation of a graphical user interface to configure the modelled quality of service attributes and the transformation of the modelled QoS attribute into policy descriptions. Finally, our approach outlines the assignment of the policies to the target Web services. This approach offers a solution, which reduces the cost and effort by the creation of QoS-aware Web services.
