Building A Highly Scalable Service that Survived A Super Bowl
summary
A small Erlang service encrypts and distributes keys for Rocket Mortgage, deployed July 2015 and serving a Super Bowl audience of ~110 million. Two senior .NET engineers build the system in about 2,000 lines of code within a 90‑day push, using Erlang, LevelDB, React Ensemble, Cowboy, LibSodium and Eximeter. Benchmarks show ~12,881 requests/sec on throwaway VMs and tooling peaks near 20,000 req/s, with sub‑1 millisecond response time in production; it remains always‑on and successful.
