Modern Enterprise Java from the Ground Up
summary
Demo builds a tiny coffee-shop WAR (11 KB) with Maven in ~3 seconds, packages it into Docker layers that push only a few kilobytes, and deploys to Kubernetes with health, metrics and config via MicroProfile/Jakarta EE. Development uses Liberty Maven plugin and Quarkus dev mode for near-instant hot redeploys, unit tests (Surefire) and integration tests (Failsafe) run fast, and config changes (version 1.2.3 → 1.2.4) reflect immediately. Claims: keep runtimes thin, prefer external config and simple CI/CD per 12-factor principles.
