Deconstructing the Monolith

on YouTube ↗41m

" summary

Shopify breaks a tangled Rails monolith into a modular monolith, reassigning roughly 6,000 Ruby classes into business components, enforcing boundaries with an in‑house tool called packwork (wedge used earlier) and mounting components as Rails engines for new services like Shopify Fulfillment Network. CI rejects new dependency violations, teams own components programmatically, onboarding and on‑call routing shrink dramatically, and thousands of developers now work productively in one deploy while keeping a clear path to extract services.
