ECMAF: An event-based cross-layer service monitoring and adaptation framework

Abstract

Although several techniques have been proposed towards monitoring and adaptation of Service-Based Applications (SBAs), few of them deal with cross-layer issues. This paper proposes a framework, able to monitor and adapt SBAs across all functional layers. This is achieved by using techniques, such as event monitoring and logging, event-pattern detection, and mapping between event patterns and appropriate adaptation strategies. In addition, a taxonomy of adaptation-related events and a meta-model describing the dependencies among the SBA layers are introduced in order to "capture" the cross-layer dimension of the framework. Finally, a specific case study is used to illustrate its functionality. © 2012 Springer-Verlag.
