| Abstract: with the improvement of science and technology,there are higher requirements for the reliability,security and stability of cloud storage service.In terms of cloud storage service,how to optimize the allocation of resources and to improve the quality of user experience. This paper proposes a method of cloud storage based on the Law of Large Numbers,in which the concrete way is to determine and redistribute users' demand for resources based on the frequency of storage and historical information by means of Bernoulli LLN,thereby reducing the data access delay. |
