Deconstructing the Monolith - Shopify

This post details Shopify's transition from a monolithic architecture to a modular monolith. It explains the advantages and disadvantages of monolithic systems, the challenges encountered at scale, and the rationale behind choosing a modular monolith over microservices. The core of the post describes the 'Componentization' project, which involved re-organizing the codebase by real-world concepts and developing tools like Wedge to enforce modularity and isolate dependencies by tracking and preventing violations of domain boundaries and data coupling across components.
