Microservices in Practice

" summary

SoundCloud migrated from a Rails monolith to small, independently deployable microservices by extracting logic only when large changes required it, keeping a thin service layer inside the monolith and an internal API to avoid big-bang rewrites. The platform — handling 12 hours of audio uploaded every minute — uses Cassandra for high-write domains, HTTP and AMQP for communication, event publication for deletes, feature-flagged progressive rollouts, circuit breakers, per-client BFFs, monitoring, and eventual-consistency patterns to prevent cascades and enable fast testing and deployment.
