This document describes the architecture and scaling challenges faced by myYearbook.com, a social networking site for teenagers. It details how the site grew from handling 100 million pageviews per month in 2007 with one database and web server, to 2.5 billion pageviews per month in 2008 using 30 database and 120 web application servers. Key lessons learned include migrating to a services-oriented architecture, horizontal and vertical scaling of PostgreSQL databases, implementing memcache, and developing internal tools like Staplr for trend analysis and an operations portal.
