Abstract:
Nowadays, enterprises are faced with a variety of major challenges, such as the cut-throat competition in a global market, a decreasing customer loyalty, and the strategic adjustment moving from a product centric perspective to a customer centric perspective. Therefore, businesses need to change their operational processes in a flexible and agile manner to keep their competitive edge. A Service-oriented Architecture (SOA) may help to meet these needs. As the application landscape of enterprises is inherently heterogeneous and highly distributed it is a great challenge to provide services with a certain quality. This is particularly the case when services are requested externally via the web. Therefore, quality of service (QoS) measurement and analysis is a crucial issue in Service-oriented Architectures. As the key contribution of this paper we present a generic SOA Quality Model (SOA QM) based on the measurement standard ISO/IEC 15939, a SOA Information Model (SOA IM), and an architectural concept of a QoS System. The SOA IM is an XML-based specification for the measurement to be performed. The QoS System provides an execution platform for the SOA IM, based on a Complex Event Processing (CEP) approach and guarantees minimal impact on the SOA environment. The concepts are explained in detail using a standard process of the German insurance domain.
