Serverless Scala - Functions as SuperDuperMicroServices
summary
Deploys a Scala chatbot as a serverless container on Cloud Run and shows end-to-end code, tests and a live Google Home invocation that works. Uses the ZIO interpreter pattern to separate effects from protocols so the same logic runs on console, telnet, unit tests and HTTP. Builds a native binary with Graal native-image to reduce cold starts (native build takes about seven minutes), demonstrates monitoring via Stackdriver and unit-testable mutable environments.
