A Flexible Attribute-Based Access Control for the Dynamic Cloud

The purpose of the cluster in order to achieve more economic expansion, the expanded use cloud computing cluster point of departure, proposed the basic framework of a cluster expansion and describe local priority strategy and cloud environments priority strategy, and in accordance with the characteristics of cloud computing, based on the calculation of the strength of the new scheduling strategy. In addition, the design of the scheduling system, and are analyzed and compared under different circumstances of each strategy, drawn based on the characteristics of the low-cost and more task to calculate the strength of the scheduling policy timeout. Finally, more economic analysis on how to use cloud computing extensions local cluster.
