From Jakarta EE over MicroProfile to Serverless: Interactive Onstage Hacking

on YouTube ↗48m

" summary

Starts from a single Maven archetype and Java 8 dependency, generates a thin WAR and deploys to Payara/Open Liberty with only CLI and IDE; adds MicroProfile 1.x/2.0 features: metrics gauge counter (increment example), circuit breaker/fallback and bulkhead annotations, Config injection, OpenAPI/Swagger and health checks, all without extra plugins. Demonstrates Docker images (example image 581 MB but layered reuse makes incremental builds tiny), and packaging a CDI/JAX‑RS/JSON‑B serverless function via the Fn project (Lambda compatible).
