Designing responsive database-driven Web sites

With the wide availability of content delivery networks, many e-commerce Web applications utilize edge cache servers to cache and deliver dynamic content at locations much closer to users, avoiding network latency. Replication of Web documents can improve both performance and reliability of the Web service. Response time is a key differentiation point among electronic commerce (e-commerce) applications. We choose to develop a framework for a secure, highly available distributed workflow architecture since interworkflow is anticipated as a major supporting mechanism for business-to-business electronic commerce. In this paper, we analyze the factors that impact the performance and scalability of a database-driven Web site.
