12 Factor, or Cloud Native Apps for Spring Developers
summary
Makes the specific claim that applying the Twelve‑Factor patterns to Spring apps and offloading ops to a platform speeds delivery and reduces friction. Shows a GitHub repo with per‑factor branches, builds with Gradle, runs Spring Boot apps via CF push into Cloud Foundry, binds a MySQL service (vcap_services), uses Flyway for migrations, sets config with CF env vars and CF set‑env, streams logs to stdout and inspects with CF logs, blue‑green routes traffic, and demonstrates fast instance startup and scaling (instances launch in ~1s).
