Greg Scallan discusses Flipboard, a social magazine app launched 6 months after an initial team put it together. It delivers relevant articles and photos based on users' social networks and interactions, and now has over 5 million users and 2 billion page views per month. To manage the complex, real-time data needs, Flipboard uses Amazon RDS MySQL and ElastiCache for its operational configuration and state data needs. RDS provides a highly performant, reliable database technology to handle Flipboard's complex queries on user and relevancy data.
