An insight into Twitter’s scaling
Though they now use multiple other technologies, it’s relatively well known in the rails community that Twitter started off as a rails site. They’ve since grown to such a scale that daily usage is in excess of 500million tweets, at an average rate of 5.7k tweets per second. The engineering blog is fascinating, and this post https://blog.twitter.com/2013/new-tweets-per-second-record-and-how explains how they’ve overcome some of the scaling difficulties.
