Bankruptcy approach to integrity aware resource management in a cloud federation

There has been a debate surrounding cloud federation in recent studies partly because of the cloud providers' profit increases and also because of resource utilization improvement. However, the main part of these studies suffers from the lack of considering integrity issues. In this paper, we provide a formal definition of cloud federation integrity in a proposing architecture and introduce a resource management mechanism inspired by the proposed solutions to the bankruptcy problem such as Talmud, Constrained Equal Awards, and Constrained Equal Loss. We utilize Social-Gap, Gini-Coefficient, Participation motivation, Deviant member destiny, and Deviation's social effects to evaluate the proposed mechanism. The obtained result in the conducted simulations based on the available bankruptcy award rules reveals that Talmud reduces the social gap by 37-55% and improves the Gini coefficient by 12-30% than other rules. Our study confirms that there is no motivation to deviate from honesty in announcing the number of virtual machines and the federation's bid price.

Automated summary

The paper discusses the issue of cloud federation integrity, proposing a formal definition and a resource management mechanism inspired by solutions such as Talmud. The simulations conducted showed that Talmud reduces social gap and improves Gini coefficient significantly, confirming there is no motivation to deviate from honesty in cloud federation.
