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. ✍️ Talk: Luca Mezzalira | The Dark Side of Micro‑Frontends 🌎 This Talk was recorded at React Advanced London 2025, Website: https://reactadvanced.com/?utm_source...
