With the rapidly growing demands for cloud resource, the task to keep it balanced with supply at all times becomes especially challenging. However, most of existing mechanisms focus on auction-based allocation of cloud resource rather than balancing the demands for cloud resource. In order to address this issue, we formulate the problem of cloud resource consumption shifting between two different time intervals, and then present a directly applicable scheme with three-tiered. Users participating in the scheme, however, are motivated to get extra rewards through shifting certain consumption quantity from high to low demand time intervals. In addition, taking into account the fact that individual shifting costs and reduction capacity vary with the different geographic areas, this scheme firstly allocates rewards to agencies in different geographic areas in the way of equilibrium. And then a strictly proper rule is proposed to reward contributors according to efficiency, which achieves the theoretical properties including equilibrium, individual rationality, and budget balance and truthfulness. At last, to verify the method given by this paper, method analysis and case study is given to illustrate the correctness and effectiveness.
