Abstract

The heterogeneity and dynamicity of services, their underlying infrastructures make the problem of adaptation and monitoring an emerging issue for service-based applications (SBA). While various approaches aim to address these problems, most of them focus on a particular element of the SBA architecture. Indeed, those approaches are fragmented and isolated; they do not consider the effect of adaptations on the whole stack of the functional layers of SBA. In this paper we study the problem of cross-layer SBA monitoring and adaptation on a series of case studies and define the requirements for the integrated approaches that provide coherent solutions to monitor and adapt the whole application. Finally we propose the mechanisms and principles that are necessary for addressing the requirements and enabling an integrated cross-layer framework.
