CNCF-hosted Co-located Events Europe 2025

Previously, the biggest constraint in our engineering department was the time it took to make infrastructure changes. In this talk I'll describe the changes we made to both our codebase, and our ways of working to remove that constraint entirely, enabling us to optimise flow across our entire engineering department, and increasing the number of active contributors to our codebase five-fold.

We'll cover how to break apart large codebases to reduce plan and apply time, how to design patterns that are easy to repeat and share, and what we did to handle shared concerns across service boundaries. We'll talk about providers in the hundreds, and workspaces in the thousands.

We'll also briefly touch on how we used this pattern to enable more engineers to work on infra code quickly, and how we enable them to do so safely, and finish up with a few points about what we'd have done differently, and sharing some metrics to illustrate the impact this had.
