MicroProfile for Dummies
summary
Live demo builds two REST microservices (service A and B) on Open Liberty using MicroProfile 4.0, wires them with a typed REST client configured via MicroProfile Config, and shows resilience with retry + timeout applied to CompletionStage responses so intermittent failures recover without changing service B. Auto-generated OpenAPI docs, /metrics, /health checks, OpenTracing spans, JWT-based role checks and a small GraphQL endpoint are all exercised interactively; hot-reload works and retries visibly reduce failed calls.
