Serverless Spring
summary
Demonstrates building a Java Function-as-a-Service using Spring Cloud Function, compiling a POJO uppercase function and running it locally, on Azure Functions and AWS Lambda (cold start ~3s then warm cached calls ~6ms), and packaging with riff and Helm to deploy riff on Kubernetes where functions scale from zero to N (example scaled to 6 pods) by monitoring Kafka lag. Shows reactive flux windowing 60s/2s stream processing, riff build/apply and HTTP gateway tests; the demos work end-to-end.
