Productivity, Sustainability, and Fun in modern Java
summary
Claims that Java is modern, fast, and lightweight with concrete examples: a prime-number microservice is built with Micronaut and compiled ahead-of-time using GraalVM native-image (native binary starts in ~30ms), Micronaut’s annotation-processor precomputation and Gradle plugin enable the native build, AWS Lambda cold starts run under ~800ms on 256MB, and a Quarkus app auto-starts a Kafka instance via Testcontainers and even runs without local Docker using Testcontainers Cloud, showing the prototypes work end-to-end.
