5 quick tips to make your Java apps more awesome
summary
Five concrete practices and a working demo: build a Jakarta EE/MicroProfile service with fault tolerance (timeouts, retries, circuit breaker, bulkheads) that fails over to a backup endpoint when a flaky backend (dice-roll failure) trips, expose health probes (liveness/readiness/startup) and /metrics for Prometheus, use feature toggles via Unleash to flip features in ~10 seconds, and manage infra as code (Terraform/Pulumi) for reproducible Kubernetes deployments; demo runs as four containers and the failover/toggle behavior works.
