Listen to the story of Sonos Voice and ZIO...
summary
Sonos Voice runs Scala with the ZIO library in production to provide on-device SLU for about 300,000 speakers while the cloud handles catalogs, authentication and playback orchestration. The team builds services from reusable ZIO layers, uses time-travel testing plus S3 and SQS mocks to run full black‑box integration tests, and learned from real load (post‑June 2022 launch) that queue-driven traffic required infrastructure fixes like rate limiting and concurrency tuning rather than application rewrites.
