Fully Booked - Zero-Downtime Migration to Self-Hosted Kubernetes
Fully Booked ran on managed cloud infrastructure with a bill that grew every month and a stack nobody fully owned. We moved the whole platform onto a self-hosted Kubernetes cluster without a minute of downtime for the people using it. The cutover covered DNS, ingress, databases and the release pipeline, staged so that traffic shifted only once each layer had been proven on the new cluster. Nobody using the app that week knew anything had happened, which was the point. The recurring bill became owned hardware, and the same cluster now carries the platform's weekly releases.
