The document discusses how Zynga scaled FarmVille from 0 to 100 million users. It describes the rapid growth, reaching milestones like 1 million daily users within 4 days of launch. To support this growth, Zynga emphasized a scalable platform using PHP and memcache on AWS, along with tools like Puppet, Nagios, and Hudson. Operations were scaled by cross-training the team, documenting processes, and implementing runtime configuration tools to change servers dynamically without redeploys.
