Replication technology is a very important data management in cloud storage. Traditional replication control methods cannot usefully solve the load imbalance caused by the hotspot access. This paper proposed a dynamic replication algorithm based on access popularity called APDRA. Replicas were created and deleted dynamically according to the popularity of data, situation of the system and the load of nodes, effectively solving the problem of local overload caused by hot spot access and the recovery of idle replicas. In the end, the superiority of APDRA was verified by experiment.
