Abstract

A major challenge in cloud computing environments is how to fairly and e_ciently allocate the various sacred physical resources of cloud providers (CPs) among multiple cloud users (CUs). In this paper, we present a novel economic model to regulate resource sharing among multiple CPs. The proposed work models the interactions among the CUs as a multidimensional game among selfish players that aims at maximizing their profits and avoiding overloads as much as possible. Firstly, we formulate the payoff function of non-cooperative CUs, consisting of the utility function, price function and penalty function. Secondly, in the framework of non-cooperative multidimensional game, we prove the existence and uniqueness of the multidimensional Nash equilibrium (NE). Finally, Simulation results demonstrate the e_ectiveness and convergence of our model.
