The Cloud@Home Resource Management System
Salvatore Distefano, Maria Carolina Fazio, Antonio Puliafito · 2011
Cloud is strongly emerging in the ICT world as the distributed computing paradigm able to raise the level of abstraction of physical resources toward a "user-centric" perspective. In this challenging scenario, we propose a new form of computing mixing Cloud and volunteer paradigms' aims and goals into Cloud@Home. In particular, this work focuses on the Cloud@Home resource management issues. In order to deal with the dynamics of the overall infrastructure, where resources asynchronously join and leave the system, we propose a solution based on autonomic and self-adapting algorithms, structuring all the available resources into a hierarchical cluster. In this paper, we first specify the architecture of the Cloud@Home resource management system and then we detail the algorithms and the mechanisms that allow to elastically manage the hierarchical cluster-based infrastructure.
