AROSA 2014 - 4th Track on Adaptive and Reconfigurable Service-oriented and component-based Applications and Architectures

The goal of this track is to bring together researchers and practitioners both from the Academia and from the Industry working in the areas of Service-oriented and component-based software applications and architectures and addressing adaptation and reconfiguration issues. Different investigation topics are involved, such as: CBSE, SOA, Functional and Non Functional (NF) requirements (QoS, performance, resilience), monitoring, diagnosis, decision and execution of adaptation and reconfiguration. Different research axes are covered: concepts, methods, techniques, and tools to design, develop, deploy and manage adaptive and reconfigurable software systems.
The development of composite services poses very interesting challenges concerning their functional and NF requirements. On the one hand, a composite software system depends on the NF requirements of its constituting components in order to provide a satisfactory service to the user. On the other hand, the main issues for the fulfillment of QoS and service level agreements (SLA) are concerned with performance variability. Indeed, the QoS may evolve frequently, either because of internal changes or because of workload fluctuations. The performance and the robustness of the composite software system may be significantly improved by monitoring the execution of the components and by flexibly reacting to degradation and anomalies in a timely fashion.
The concept of adaptive and reconfigurable software systems has been introduced in order to describe architectures which exhibit such properties. An adaptive and reconfigurable software system can repair itself if any execution problems occur, in order to successfully complete its own execution, while respecting functional and NF agreements. In the design of an adaptive and reconfigurable software system, several aspects have to be considered. For instance, the system should be able to predict or to detect degradations and failures as soon as possible and to enact suitable recovery actions. Moreover, different NF requirements service levels might be considered in order to complete the execution in case of failure.
