Mastering Challenges of Cloud-Native Architectures With Spring
summary
Step-by-step walkthrough of a runnable supply‑chain demo (order, product, shipping) shows synchronous REST plus RabbitMQ async wiring, externalized config via Spring Cloud Config with live /actuator/refresh, service discovery and client load‑balancing, Redis caching, and circuit breakers implemented with Resilience4j fallbacks. Build pipeline notes include layered Docker images, Cloud Native Buildpacks / kpack, AOT cache and GraalVM native images; measured wins: JDK 21 gives ~10% faster startup and AOT/Graal approaches report up to ~65% startup reduction, all demonstrated working locally from the repo.
