Abstract. In this paper we show how the application of the aspectoriented programming paradigm to runtime adaptation of service compositions can be used to prevent SLA violations. Adaptations are triggered by predicted violations, and are implemented as substitutions of fragments in the service composition. Fragments are full-fledged standalone compositions, and are linked into the original composition via special activities, which we refer to as virtual activities. Before substitution we evaluate fragments with respect to their expected impact on the performance of the composition, and choose those fragments which are best suited to prevent a predicted violation. We show how our approach can be implemented using Windows Workflow Foundation technology, and discuss our work based on an illustrative case study.

“…Recently, work in this area seems to have gravitated towards using the aspect-oriented programming (AOP) paradigm to technically implement adaptation, as exemplified by [9,14]. Other approaches use pure service rebinding [8] or parametrization of compositions [15]. The PREvent framework [2] supports adaptation on many different levels, and forms the basis of the research work presented in this paper.…”

Abstract. Existing research work considers runtime adaptation of service compositions as a viable tool to prevent violations of service level agreements. In previous work we have formalized the optimization problem of identifying the most suitable adaptations to prevent a predicted set of violations, and presented suitable algorithms to solve this problem. Here, we introduce the idea of stepwise optimization as a solution to the problem of how to deal with situations when the optimization result is not available in time, i.e., when decisions need to be taken before the optimization problem can be fully solved.

“…To enable the communication among the parts of a global process that run at different locations and hence be able to coordinate these partitions/fragments each service composition engine needs to provide information about events related to the life-cycle of process instances. Usually, an engine implements an event model, which is used to publish information for the purposes of monitoring; this has been used for enabling monitoring [9], adaptation [16] [8] [9] and a framework for coordination of service compositions [11]. These are all examples of the use of the events published by the engine, based on an event model.…”

Abstract. Outsourcing parts of a company's processes becomes more and more important in a globalized, distributed economy. While architectural styles and technologies such as service-oriented architecture and Web services facilitate the distribution of business process over several departments, enterprises and countries, these business processes still need to comply with various regulations. These regulations can be company regulations, national, or international regulations. When outsourcing IT-functions, enterprises must ensure that the overall regulations are met. Therefore they need evidence from their outsourcing partners that supports the proof of compliance to regulations. Furthermore it must be possible to enforce the adherence to compliance rules at partners. In this paper we introduce so-called compliance interfaces that can be used by customers to subscribe to evidence at a provider and to enforce regulations at a provider. We introduce a general compliance architecture that allows compliance to be monitored and enforced at services deployed in any emerging cloud delivery model.
