CaaS Model for Cloud Consistency

Now a day, due to the overwhelming advantages cloud storage services become popular. Multiple replicas for each piece of data are stored on geographically distributed servers inorder to provide always on access. The main drawback of keeping such replicas is that it requires high cost for providing strong consistency. In this paper proposing a CaaS model, which is comprised of a data cloud and multiple audit clouds. We are implementing a two level auditing structure. At last heuristic auditing strategies are to reveal violations.
