Strategy analysis for cloud storage reliability management based on game theory
What is it about?
In this paper, we address the conflict between a user and the CSP, where a user prefers less auditing and the CSP prefers less replication. We propose a game-theoretic analysis to find out optimal strategies for a user and the CSP. We treat a user and the CSP as rational players who make decisions depending on their preferences only. Their strategies affect each other.
Why is it important?
In this paper, we describe a game-theoretic analysis to design optimal strategies for users and cloud storage provider (CSP). We use the pricing strategy adopted by Amazon S3 to explain our analysis. We analyze the effect of changes in pricing on the Nash equilibrium and the Bayesian Nash equilibrium. According to these results, a user can determine whether to pay for auditing by the pricing tags, and CSP can formulate appropriate policies for reliability and pricing. The paper should be of interest to readers in the areas of cloud storage reliability management.
