Towards On-Demand Web Application Replication

Abstract

The increasing popularity of Web applications drives the need for systems that offer improve high performance web services by replicating applications at geographically distributed servers. In this paper, we propose a system for Web application replication that replicates both application code and its data. A key challenge in such a system is data replication and consistency, so that each replica server can access its shared data locally thereby avoiding the wide-area network latency that would be incurred by a traditional centralized database. In our system, we aim to minimize this consistency overhead using partial replication where data units are replicated to servers that only access them. This would reduce the consistency overhead as updates are sent only to servers that access them. We explore the design space of this system, find the key issues that need to be addressed to build it and propose solutions to solve them.
