Acceleration of Data Center-Hosted Distributed Database-driven Web Applications

Response time is essential to many Web applications. Consequently, many database-driven Web applications rely on data centers that host applications and database contents. Such IT infrastructure enables generation of requested pages at locations much closer to the end-users, thus reducing network latency. However, it incurs additional complexity associated with database/data center synchronization and data freshness. In this paper, we describe the deployment of NEC's CachePortal dynamic content caching technology on a database-driven Web site in a data center-based distribution infrastructure. The new system architecture has been experimentally evaluated and the results show that the deployment of NEC's CachePortal accelerates the dynamic content delivery up to 7 times while attaining a high level of content freshness.
