Abstract:
The globalized markets now offer customers a variety of products and services as never before. This enormous selection reduces the loyalty of the customers to the companies. Today, products and services are highly interchangeable. This requires a strategic rethinking of the companies 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 maintain their competitive edge. A Service-oriented Architecture (SOA) may help to meet these need. Particularly in the insurance industry, this is an established key technology. Old monolithic software architectures have already been successfully transformed to 'traditional' SOAs. This could even be a good basis for future upgrades to micro-service architectures. But, before this upgrade is accomplishable, it is necessary to analyze and measure the already established SOA. As the application landscape of enterprises is inherently heterogeneous and highly distributed, it is a great challenge to provide services with a certain quality. A measurement system can help to capture the relevant QoS parameters of a software architecture. 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. Moreover, implementation details for our concept are given, including an overview of the general deployment of such a technology.
