What to do if Justin Bieber starts using your app

In this video, Sarah speaks about Instagram's Justin Bieber problem, in which data retrieval from Justin Bieber's images would cause the site to slow to a crawl. Sarah walks through two approaches Instagram implemented to deal with large amounts of asynchronous data: denormalizing their like counter, and using a database queue. Sarah also explains when and how you can create a scalability plan for your own apps.
