By a News Reporter-Staff News Editor at Computer Weekly News -- Investigators publish new report on Cluster Computing. According to news reporting from Valdosta, Georgia, by VerticalNews journalists, research stated, "Virtualization is widely used in cloud computing environments to efficiently manage resources, but it also raises several challenges. One of them is the fairness issue of resource allocation among virtual machines."
The news correspondents obtained a quote from the research from Valdosta State University, "Traditional virtualized resource allocation approaches distribute physical resources equally without taking into account the actual workload of each virtual machine and thus often leads to wasting. In this paper, we propose a virtualized resource auction and allocation model (VRAA) based on incentive and penalty to correct this wasting problem. In our approach, we use Nash equilibrium of cooperative games to fairly allocate resources among multiple virtual machines to maximize revenue of the system. To illustrate the effectiveness of the proposed approach, we then apply the basic laws of auction gaming to investigate how CPU allocation and contention can affect applications' performance (i.e., response time), and its effect on CPU utilization. We find that in our VRAA model, the fairness index is high, and the resource allocation is closely proportional to the actual workloads of the virtual machines, so the wasting of resources is reduced."
According to the news reporters, the research concluded: "Experiment results show that our model is general, and can be applied to other virtualized non-CPU resources."
