Incentive-aware virtual machine scheduling in cloud computing

Abstract

As cloud computing is a market-oriented utility, optimal virtual machine (VM) scheduling in cloud computing should take into account the incentives for both cloud users and the cloud provider. However, most of existing studies on VM scheduling only consider the incentive for one party, i.e., either the cloud users or the cloud provider. Very few related studies consider the incentives for both parties, in which the cost, one of the most attractive incentives for cloud users, is not well addressed. In this paper, we investigate the problem of VM scheduling in cloud computing by optimizing the incentives for both parties. The problem is formulated as a multi-objective optimization model, i.e., maximizing the successful execution rate of VM requests and minimizing the combined cost (incentives for cloud users), and minimizing the fairness deviation of profits (incentive for the cloud provider). The proposed multiobjective optimization model can offer sufficient incentives for the two parties to stay and play in the cloud and keep the cloud system sustainable. A heuristic-based scheduling algorithm, called cost-greedy dynamic price scheduling, is then developed to optimize the incentives for both parties. Experimental results show that, compared with some popular algorithms, the developed algorithm can achieve higher successful B Yang Liu

Multi‐objective container scheduling and multi‐path routing for elastic business process management in autonomic multi‐tenant cloud

“…The main aim was to maximize the resource utilization and the technique followed a self‐management mechanism to monitor and analyze the cloud system to obtain the historical data regarding the resource usage. A heuristic‐based resource scheduling strategy was formulated by Xu et al 31 using the cost‐greedy dynamic price scheduling (CGDPS) algorithm to satisfy both the users and the cloud service providers through the optimization of cost. The algorithm utilized the price adjusting function to adjust the prices of all the nodes by means of reducing the deviation.…”

“…The execution time of the model is found to be very high compared to the proposed method even under minimum load. The incentive‐aware approach formulated by Xu et al 31 focused on improving the overall execution rate of the requests arriving the cloud. Also, the approach tried to profit both the users and providers associated in the environment.…”

A multi-objective optimization for resource allocation of emergent demands in cloud computing

“…Another classical method of cloud resource allocation is to model VM placement as a multi-objective optimization mathematical problem [9][10][11]. The main idea is to express a cloud resource allocation problem as a multi-objective mathematical function, and then to use a multi-objective evolutionary algorithm to solve it.…”
