Why Your Micro‑Frontends are a Distributed Monolith | AWS Architecture | Luca Mezzalira

How to scale frontend architecture across hundreds of teams and achieve independent deployment? 🏗️ Solving the primary pain points of micro-frontends.

Luca Mezzalira (Principal Architect at AWS, Author of "Building Micro-Frontends") shares architectural strategies derived from working with 100+ AWS engineering teams👨‍💻

You will learn:
✔️ Optimizing for Team Independence over Code Reusability.
✔️ Using Coarse-Grained Splitting to reduce cognitive load.
✔️ Designing technology-agnostic and stable Application Shells.
✔️ Implementing Dynamic Discovery Schemas for flexible routing.
✔️ Managing Canary Releases and instant rollbacks on the Edge.
✔️ Data sharing via BFF and Event Emitters instead of Global State.
