Elixir Adoption at Scale: A Comprehensive Guide
summary
Bleacher Report runs Elixir and Phoenix in production for about three years and reports concrete wins: monitoring with Observer and Exometer, style gates with Credo and coverage with Coveralls, CDN via Fastly, and Datadog for metrics. The push system sends 225 million push notifications in three hours; load tests show the platform sustains eight times normal traffic with 95th‑percentile response times around 100–150 ms, fewer servers, removed Redis, and markedly improved reliability and developer happiness.
