Dissecting Serverless Enterprise Java Applications #slideless
summary
Live demo deploys a Quarkus Java microservice to AWS Lambda via CDK deploy, packaging a function.zip with Maven and using DynamoDB on‑demand for persistence. Cold start measures ~0.5–3s then steady responses ~10ms; build duration shows 3ms billed runtime. Cost examples: 2GB Lambda ≈ €15/month, tiny EC2 ≈ €8/month, small RDS ≈ €80/month. Shows granting table permissions in CDK, function URLs, concurrency scaling (thousands), connection‑pool issues with RDS and RDS Proxy, and a working multi‑endpoint deployment.
