On the performance of content delivery clouds

Abstract

Extending the traditional Content Delivery Network (CDN) model to use Cloud Computing is highly appealing. It allows developing a truly on-demand CDN architecture based upon standards designed to ease interoperability, scalability, performance, and flexibility. To better understand the system model, necessity, and perceived advantages of Cloud-based CDNs, this chapter provides an extensive coverage and comparative analysis of the state of the art. It also provides a case study on the MetaCDN Content Delivery Cloud, along with highlights of empirical performance observations from its world-wide distributed platform.
