Cloud computing has become more popular in terms of providing resources and services to the costumers. In cloud service provider perspective profit is one of the most important consideration. Profit can be determined by the configuration of cloud service platform under given market demand. At present single long term renting scheme is used which has some of the drawbacks like resource wastage, no guaranteed service quality. To overcome these drawbacks, in this paper we are proposing a double resource renting scheme. A double resource renting scheme is the combination of short-term renting and long-term renting aiming at resolving the existing issues. Secondly, service system is assumed as M/M/m+D queuing model and the performance indicators are also analyzed. Here the waiting time(D) is not fixed like the existing system. Thirdly, a profit maximization problem is formulated for the double renting scheme and solved to obtain optimized configuration of cloud platform. Finally, a series of calculations are conducted to compare the profit of our proposed scheme with that of existing scheme. Obtained results specify that our proposed scheme not only guarantee the quality of all requests but also generated profit more than the existing system.
