Shopify went in a different direction, and there is a lot .NET developers can learn from that. In this video, I break down how Shopify evolved its architecture into a modular monolith, why that decision made sense at their scale, and what lessons apply directly to building large systems in .NET. We go beyond the usual monolith vs microservices debate and focus on the real architectural issues that matter: boundaries, coupling, cohesion, and how to keep a large codebase maintainable as teams and complexity grow. What we cover: - Why Shopify is such an interesting architecture case study - The difference between a traditional monolith and a modular monolith - Why internal boundaries matter more than most teams realize - The problems caused by tight coupling in large systems - How modularity improves maintainability and team autonomy - The tradeoffs between modular monoliths and microservices - What .NET developers can apply in their own applications - Why scale does not automatically mean you need microservices This is a practical breakdown for developers and architects who want to build systems that scale without creating unnecessary complexity.
