Quality of service in cloud computing with a profit maximization scheme

Abstract

In this paper, a double resource renting scheme is designed to begin with in which quick-term renting and lengthy-time period renting are combined aiming at the existing problems. This double renting scheme can quite simply assurance the satisfactory of carrier of all requests and cut down the useful resource waste widely. Secondly, a provider system is viewed as an M/M/m+D queuing model and the efficiency indications that have an effect on the revenue of our double renting scheme are analyzed, e.g., the average charge, the ratio of requests that need transitority servers, and so on. Thirdly, a profit maximization main issue is formulated for the double renting scheme and the optimized configuration of a cloud platform is bought through solving the revenue maximization difficulty. Finally, a series of calculations are conducted to compare the revenue of our proposed

scheme with that of the single renting scheme. The results show that our scheme can't most effective warranty the service quality  of all requests, but also obtain more revenue than the latter.
