Abstract
This chapter explores the issues of content delivery through CDNs, with a specialfocus on the delivery of dynamically generated and personalized content. Wedescribe the main functions of a modern Web system and we discuss how the deliveryperformance and scalability can be improved by replicating the functions ofa typical multi-tier Web system over the nodes of a CDN. For each solution, wepresent the state of the art in the research literature, as well as the available industrystandardproducts adopting the solution. Furthermore, we discuss the pros and consof each CDN-based replication solution, pointing out the scenarios that provides thebest benefits and the cases where it is detrimental to performance.
