A cloud computing is becoming increasingly popular; cloud storage services attract more attentions for their high security and availability with a low cost. Cloud storage is expected to become the main force of the future storage market. As a key technology of cloud computing, replication faces new challenges, especially replica consistency. The intrinsic characteristic heterogeneous of cloud applications makes their consistency requirements different where the consistency requirement of certain application changes continuously at runtime. This paper presents a runtime replica consistency mechanism for cloud data storage to achieve a dynamic balance between consistency and performance. Evaluation result show that the propose mechanism guaranteeing the consistency and decrease the overhead.
