In this paper, the authors develop a scalable geo replicated storage back ends for web applications. Web application mostly requires a storage system replicate across different sites also scalable. Generally, they use traditionally database having strict consistency guarantee and programming ease, but in concern in geo replicated no SQL are scalable and efficient. For scalable and geo replicated storage for web application they have two system Walter and Lynx. Walter supports transactions and replication of data across sites.
