Jeff Rothschild, VP for Technology at Facebook, shared some detailed insights into Facebook architecture. Over the past few years, Facebook has grown into one of the largest sites on the Internet today serving over 200 billion pages per month and with more than 300 million users. The nature of social data makes engineering a site for this level of scale a particularly challenging proposition. In this presentation, Jeff discussed the aspects of social data that present challenges for scalability and the core architectural components and design principles that Facebook has used to address these challenges. He also discussed emerging technologies that offer new opportunities for building cost-effective high performance web architectures.
