Live Coding: cloud-native application development with MicroProfile and Open Liberty
summary
Live demo builds two Java services using MicroProfile 5 and Open Liberty dev mode, coded in VS Code, packaged with Maven and Docker (OpenJ9 JVM), and deployed to Kubernetes. Service A calls Service B via the MicroProfile REST client; live reload shows config and code edits immediately. MicroProfile features used: metrics, OpenAPI UI, JWT auth with groups/UPN, health/readiness probes, and timeout + retry + fallback to turn intermittent slow failures into steady responses; Docker and kubectl deployment complete successfully.
