Dynamically Reconfigurable Resource-Aware Component Framework: Architecture and Concepts

Abstract. Applications executed on a shared distributed platform compete for resources provided by the platform. In case these applications have highly fluc-tuating resource demands, a software architecture is required that provides sup-port for runtime resource management. In position paper [1], we have proposed such architecture and have introduced its key concepts and entities. In this pa-per, we introduce a metamodel that captures the key concepts and we identify lifecycle models for both applications and individual components. A set of dy-namic reconfiguration strategies is introduced and their relationship to the stag-es of the application lifecycle is given
