Serverless Spring
summary
Spring Cloud Function provides a bean-based model where a single Function<String,String> (example: uppercase) becomes an invocable endpoint, and demoed wiring to HTTP and Kafka adapters. Startup measurements: a non-web Spring context starts ~800ms, tiny micro app ~200ms, devtools warm restart ~100ms; AWS Lambda cold starts run multiple seconds and billed ~5,800ms then fall to ~100ms minimum, with memory increases cutting cold-start time. A Kubernetes demo builds a Docker image, deploys project riff with Kafka routing, and the riff publish returns the expected response using spring cloud function.
