Dynamically Reconfigurable Resource-Aware Component Framework: Architecture and Concepts

摘要

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