With the increasing popularity of cloud computing, there is an increased demand for cloud resources in cloud. It has become even more urgent to find solutions to improve resource utilization. From the perspective of a cloud consumer, a cloud application processes a large information flow involving user actions that access resources, but little work has so far been devoted to research from the perspective of the interaction between the user and the cloud application. In this paper, we analyze the interaction in detail, and propose a general mathematical interaction model to formulate the challenge pertaining to storage resource allocation as an optimization problem, focusing on minimizing both the user's cost and server's consumption. A potential response mechanism is then designed based on the interaction model. Furthermore, the proposed model is used to explore strategies when multiple users access the same file simultaneously. Additionally, an improved queuing system, namely M/G/∞ queue with standby, is introduced. Finally, an evaluation is presented to verify the interaction model.
