With the availability of content delivery networks (CDN), many database-driven Web applications rely on data centers that host applications and database contents for better performance and higher reliability. However, it raises additional issues associated with database/data center synchronization, query/transaction routing, load balancing, and application result correctness/precision. In this paper, we investigate the issues in the context of data center synchronization for such load and precision critical Web applications in a distributed data center infrastructure. We develop a scalable scheme for adaptive synchronization of data centers to maintain the load and application precision requirements. A prototype has been built for the evaluation of the proposed scheme. The experimental results show the effectiveness of the proposed scheme in maintaining both application result precision and load distribution; adapting to traffic patterns and system capacity limits.
