Microservices based off Akka cluster at iHeartRadio
summary
iHeartRadio builds a microservice platform called Powerand using Akka Cluster for binary-typed RPC, a Play API Gateway that serves HTTP routes defined inside services, and SBT/Docker scripts for blue‑green deploys on AWS. it ships three OSS projects: canala (reactive work pipeline with automatic optimal concurrency discovery — observed optima like ~8–10 for a DB and ~300 for a high‑throughput web API), the distributed REST DSL, and centralized distributed Swagger generation. the system adds circuit breakers, metrics, node/commit monitoring, and contributed the concurrency feature back into Akka.
