Carson: On the Path from Big-Ball-of-Mud to SOA

on YouTube ↗34m

" summary

Carson is a rails 3 host that runs many engines as gems so teams get Carson engine isolation, fast per-project test suites, and decoupled deploys via semantic versioning. Zendesk runs ~3–4 Rails 3 features and ~30–50 Rails 2 features, CI deploys patch updates every 15 minutes when backed by an internal gem server. Tradeoffs: single VM and central DB, global state risks, and extra dependency meetings. Patterns that work: namespacing, ActiveSupport::Notifications, read-only model copies, and client-first service layers.
