Playtomics is a game analytics service which migrated from .NET to NodeJS for significant server savings. Read about how they did it and what the performance is like in this detailed article.
Just over 20,000,000 people hit my API yesterday 700,749,252 times, playing the ~8,000 games my analytics platform is integrated in for a bit under 600 years in total play time. That’s just yesterday. There are lots of different bottlenecks waiting for people operating at scale. Heroku and NodeJS, for my use case, eventually alleviated a whole bunch of them very cheaply.
