Abstract
This chapter provides an overview on the recent advances and perspectives on content delivery networks (CDNs). After a reminder on the definition and core features of CDNs, the first section highlights their importance with quantitative illustrations. The second section identifies the various types of CDNs which have been deployed to address different markets. The growth of the CDNs has been driven primarily by video streaming. Next to media content, CDNs have evolved to deliver always more demanding social networks and applications. Security solutions are now fully integrated into CDNs and marketed as flagship products. The third, fourth, and fifth sections outline the challenges and technical evolutions of the CDNs to keep up with their customers' hunger for media content, web performance, and security. The sixth section focuses on the convergence of CDNs and clouds. The seventh section reviews the status and perspectives of different approaches for using multiple CDNs. The last section presents the current positioning and future perspectives of the CDNs in the mobile domain.
