Level 8: The Architecture
Structuring systems at scale: monoliths, microservices, serverless, and cross-cutting concerns.
Welcome to Level 8
Architecture is about making structural decisions that are hard to change later. This level covers the spectrum from monoliths to microservices, service decomposition, API gateways, service meshes, serverless, and the cross-cutting concerns every production system needs.

Key Takeaway
Architecture decisions are the most expensive to reverse. Understand the full spectrum from monolith to microservices, and choose based on your team size, domain complexity, and operational maturity — not industry hype.
