The document discusses Blinkist's migration from a dedicated server infrastructure to cloud-based services on Heroku and MongoDB. It describes initial issues with downtime on the dedicated server and slow boot times with Java Spring applications on Heroku dynos. It then outlines Blinkist's switch to using Ruby on Rails applications with services like Heroku, S3, Codeship, New Relic, MemCachier, Logentries, MongoHQ, and others to improve performance, scalability and reduce costs.
