I’ve read two really good books on scaling large-scale web applications lately: Building Scalable Websites by Cal Henderson and Scalable Internet Architectures by Theo Schlossnagle. (Original titles, eh?) Both dispel common myths and misconceptions about scaling. While neither maps directly to the approaches we’re taking at Automattic, they’re both must-read for developers approaching or past the million/day pageview mark. I only wish I had more time to discuss my thoughts on the various concepts in the books—particularly Cal’s.
