Abstract: On the basis of Google open cloud environment, through the analysis of network topology and location information based on the relationship between the server location in the cloud environment, this paper gets hierarchical network topology map of collection of data blocks in the cloud environment, and gets risk assessment model through the analysis of data block distribution to the storage resources in the cloud environment and gives specific examples of risk calculation algorithms and specific example analysis and provides a theoretical risk basis for cloud storage resources in the cloud environment.

Key words: cloud computing, cloud storage, scalability, reliability, risk model, load balancing
