This presentation provides a practical, in-depth look at City Storage Systems' three-year experience of running CockroachDB on Kubernetes as our main production database. We'll share the lessons learned from building a home-grown Kubernetes operator and achieving multi-region and multi-cloud compatibility, including a successful cloud migration. We will discuss cost and reliability tradeoffs, as well as showcase trials and triumphs in implementing resizable disks, CPU autoscaling, topology considerations, disaster recovery tooling, and more. Join us as we explore the highs and lows of our cloud adventure.
