The Weekly Dev's Brew Microfrontends: Cutting Through the Hype and Misconceptions (w/ Luca)
Micro-frontends promise to help teams scale development, but AWS Principal Architect Luca Mezzalira has seen some succeed and some just fall apart. In this conversation, he shares what he's learned from years of implementation work at companies like DAZN and through consulting with Fortune 500 organizations.
Luca explains why micro-frontends are fundamentally different from components—something many teams get wrong from the start. He discusses the common pitfalls he encounters: teams treating them like distributed components, sharing state across boundaries, and copying architectures from companies with completely different constraints and resources.
The discussion covers practical implementation details—from communication patterns and tooling strategies to when approaches like iframes actually make sense. Luca also touches on newer developments in server-side rendering and how they're changing the micro-frontend landscape.
This isn't about micro-frontends being good or bad, but about understanding when and how to use them appropriately. Luca emphasizes the importance of context and organizational design in making these architectural decisions work.
