Penalty‐aware and cost‐efficient resource management in cloud data centers

Summary Today, data centers are the main source of providing cloud services through a service level agreement (SLA). Most research papers for cloud resource management concentrate on how to reduce host energy consumption and SLA violation (SLAV) to minimize operational cost. However, they do not consider the amount of penalty that cloud provider should pay to users because of SLAV. In this paper, we propose a new penalty‐aware and cost‐efficient method that considers cloud resource management as a cost problem. In this method parameters such as user budget, penalty, and host energy consumption cost play an important role in minimizing operational cost which leads to higher profit for cloud provider. The simulation results with CloudSim show that our proposed method minimizes operational cost compared to the prior resource managements. Copyright © 2016 John Wiley & Sons, Ltd. This paper focuses on how to reduce host energy consumption and service level agreement violation to maximize cloud provider profit. Hence, we consider cloud resource management as a cost problem with considering power cost as well as penalty cost of individual virtual machines because of service level agreement. Simulation results demonstrate that the proposed penalty‐aware and cost‐efficient method maximizes cloud providers profit by minimizing operational costs.
