Domain-Specific Service Selection for Composite Services

The authors propose a domain-specific service selection mechanism and system implementation to address the issue of runtime adaptation of composite services that implement mission-critical business processes. To this end, they leverage Quality of Service (QoS) as a means to specify rigid dependability requirements. QoS does not include only common attributes such as availability or response time but also attributes specific to certain business domains and processes. Therefore, they combine both domain-agnostic and domain-specific QoS attributes in an adaptive QoS model. For specifying the service selection strategy, they propose a domain-specific language called VieDASSL to specify so-called selectors. This language can be used to specify selector implementations based on the available QoS attributes.
