Providing Consistency in Cloud Using Read after Write Technique to Endusers

R.Jeena, S.Saravanakumar, B.Poornima Bharathi, R.P.Priyancaa

A cloud service provider maintains multiple replicas for each piece of data on geographically distributed servers. In Existing system ,there occurs conflict in shared files,if one member in the group opens the file and editing or do some operations,if another member in the group opens and modifies the same file which is being used by another one then there occurs a conflict. In existing the algorithm used is HAS,heuristic auditing strategy but in proposed we are following Read-after-write consistency allows you to build distributed systems with less latency. As touched on above, without read-after-write consistency you’ll need to incorporate some kind of delay to ensure that the data you just wrote will be visible to the other parts of your system.
