Nowadays the development of Grid/Cloud networks has accelerated to meet the increasing requirements for largescale computing, storage and network capabilities by consumers. Therefore how to improve the resource utilization in the Grid/Cloud to satisfy more task requests from users is becoming important. The objective of our investigation in this paper is to minimize the expense the consumers incur while obtaining the resources they request from Grid/Cloud networks. We propose a Tabu search based heuristic to solve joint resource allocation and task scheduling problem in Grid/Cloud networks, and examine the performance of the proposed method. The experimental results are analyzed and compared with the Best-Fit method we proposed in our earlier work. The results show that the Tabu search based heuristic method will equal or outperform the Best- Fit heuristic, and both can achieve approximate optimal solutions to the corresponding MILP (Mixed Integer Linear Programming) solutions. In addition, compared to the Best-Fit method, the Tabu search based heuristic will reduce the traffic blocking rate by 4%∼30% generally under different job scheduling policies.
