On the benefits and costs of offloading among cooperating clouds

A model of two multi-class service provisioning clouds which cooperate by offloading jobs from one to the other is analysed in the steady state. The costs of successful and unsuccessful offloading are set against the revenues obtained by serving local and offloaded jobs. The solution is based on approximate class decomposition and fixed-point iterations. It may be generalized to more than two cooperating clouds. The results of several numerical and simulation experiments are presented.

Automated summary

This study analyzes a model of two multi-class service provisioning clouds cooperating with each other, examining the costs and revenues associated with offloading jobs. The solution is based on approximate class decomposition and fixed-point iterations, and can be applied to more than two cooperating clouds. The results of numerical and simulation experiments are presented to demonstrate the effects of successful and unsuccessful job offloading on revenues from local and offloaded jobs.
