NDC Conferences: Migrating from a monolith to a new service - Connell Sharp - NDC Copenhagen 2025

This NDC Copenhagen talk walks through how the Stack Overflow team peeled a small feature out of their massive monolith, gave it its own database, rewrapped the UI as a microfrontend with a fresh framework, and rolled it out without a single second of downtime. Along the way you’ll see how they kept things smooth in production, from data migration to deployment.

They also dive into real-world headaches like eventual consistency, multi-tenant data isolation, circular references and CORS, sharing the options they weighed and the lessons they learned from each choice. It’s a practical, no-fluff look at migrating to microservices and microfrontends.
