Abbott and Fisher’s previous book, The Art of Scalability received good reviews for shifting the way we think about scalability from merely splitting databases and adding servers, to include the human factors that weigh heavily on its success. Together with the authors’ distinguished pedigree (PayPal, Amazon, and eBay between them), I picked up a copy of their second book, Scalability Rules – 50 Principles for Scaling Web Sites without a second thought.
If Art was about laying a strong foundation for a scalable organization then Rules is the reference point for when you actually tackle the growth challenges. It acts as a reminder when you come to a crossroad of decision-taking, to keep with the principles of scaling. Each guiding principle is clearly explained and illustrated with examples. It also prescribes how and when to apply the rules.
