Next-Generation Cloud Native Apps with Spring Boot 3
summary
Spring Boot 3 requires Java 17 baseline and shows concrete gains: the demo app drops from ~4s startup and 113MB heap on Java 8 to ~1.5s and ~half the memory on Java 11 and improves further on Java 17. Builds use Cloud Native Buildpacks (boot build-image) or GraalVM native images for millisecond startup and smaller attack surface. Persistence uses records + Spring Data JDBC, Flyway and Postgres; Testcontainers for dev+CI replaces Docker Compose for consistent local and test databases. Observability via Micrometer/OpenTelemetry, Prometheus, Tempo, Loki and Actuator works end-to-end.
