A Taxonomic Specification of Cloud@Home

摘要

In this paper we present the Cloud@Home paradigm as an effective solution to the problem of building open and interoperable Clouds. In this new paradigm, users' hosts are not passive interface to Cloud services anymore, but they can interact (for free or by charge) with other Clouds, that therefore must be able to interoperate. Such innovative paradigm merges goals of Cloud and Volunteer computing by aggregating the computational potentialities of many small, low power systems, exploiting the long tail effect of computing. This paper, starting from a well-known Cloud layered taxonomy, try to implement such goals into a specific logical architecture and the corresponding middleware core structure, therefore deployed into a physical infrastructure.
