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

In this talk from NDC Copenhagen 2025, the Stack Overflow team walks through how they carved a tiny feature out of their huge monolith and turned it into a standalone microservice. They moved the data to a new database, rebuilt the UI as a microfrontend on a fresh framework, and managed a zero-downtime deployment.

Along the way, they tackled eventual consistency headaches, multi-tenancy puzzles, circular reference tangles, CORS woes, and more. You’ll hear about the trade-offs they weighed, the paths they chose (and why), and the lessons they picked up during this migration experiment.
