summary
Argues that the real claim is concrete: measuring and refactoring code reveals service boundaries, not buzzwords. Shows a largest ActiveRecord model at 1100 lines and uses a CodeClimate-style complexity vs churn scatter to locate trouble. Demonstrates refactorings like extract class to turn duplicated logic into testable objects, warns against a shared database and lock‑step deploys, and reports that smaller classes (and then smaller services) actually make SOA feasible and cheaper to learn.
