Descartes Vision Paper to be presented at IEEE SCC 2010

The long-term vision and approach of the Descartes research project "Towards self-aware performance and resource management in modern service-oriented systems" by Samuel Kounev, Fabian Brosig, Nikolaus Huber, and Ralf Reussner will be presented as part of the Work-In-Progress Track at the 7th International Conference on Services Computing 2010.

Abstract:
Modern service-oriented systems have increasingly complex loosely-coupled architectures that often exhibit poor performance and resource efficiency and have high operating costs. This is due to the inability to predict at run-time the effect of dynamic changes in the system environment (e.g., varying service workloads) and adapt the system configuration accordingly. In this paper, we describe a long-term vision and approach for designing systems with built-in self-aware performance and resource management capabilities. We advocate the use of architecture-level performance models extracted dynamically from the evolving system configuration and maintained automatically during operation. The models will be exploited at run-time to adapt the system to changes in the environment ensuring that resources are utilized efficiently and performance requirements are continuously satisfied.
