Cloud storage services have become commercially popular now a day. To provide unique and updated access of file on cloud, a Cloud Service Provider (CSP) maintains multiple replicas for each piece of data on geographically distributed servers. The main problem of using the replication technique in clouds is that it is very costly to maintain consistency among data on clouds. In this paper, the authors first present a novel Consistency-as-a-Service (CaaS) model, which consists of a large data cloud and multiple small audit clouds.
