Cloud computing realizes a utility computing paradigm by offering shared resources through an Internet-based computing.
However, how a system control can enhance profit and simultaneously satisfy the service level agreements (SLAs) has become one of the major interests for cloud providers.
In this paper, a cloud server farm provided with finite capacity is modeled as an M/M/R/K queuing system.
Revenue losses are estimated according to the system controls and impatient customer behaviors.
Three important issues are solved in this paper.
First, a profit function is developed in which both the system blocking loss and the user abandonment loss are evaluated in total revenue.
A tradeoff between meeting system performances and reducing operating costs is conducted.
Second, the effects of system capacity control and utilization on various performances of waiting time, loss probability, and final arrival rate are demonstrated.
Finally, the proposed optimal profit control (OPC) policy allows a cloud provider to make the optimal decision in the number of servers and system capacity, so as to maximize profit.
As compared to a system without applying the OPC policy, enhancing providers’ profit and improving system performances can be obtained.
