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.
