Scale your @Controller to zero with AWS Lambda or Azure Function

on YouTube ↗47m

" summary

Shows that an existing Spring Web @Controller app runs on AWS Lambda or Azure Functions using Spring Boot and Spring Cloud Function with an adapter, requiring no code changes to controllers; demo deploys a sample petstore and an uppercase function via Spring Cloud Function + AWS adapter and API Gateway. Cold starts without optimizations are about ~3.5s, enabling AWS SnapStart cuts that to roughly ~300–350ms for first restore and subsequent requests drop to ~2–3ms, and the deployed endpoints work as expected.
