City Storage Systems, a startup in the real-estate and foodtech space, has successfully implemented a scalable global infrastructure using CockroachDB and Kubernetes, as discussed by engineering manager Rasmus Bach Krabbe and software engineer Frederick Stenum Mogensen at RoachFest. By leveraging CockroachDB for their OLTP workloads, the company has minimized manual labor and reduced human error, despite initial challenges with manual cluster provisioning and scaling. To overcome these issues, they developed a custom Kubernetes operator, streamlining the deployment and management of resources, which significantly simplified operations such as cloud migrations. This approach has provided City Storage Systems with a highly available and consistent database solution capable of supporting multi-region and multi-cloud environments, ultimately aligning with their global ambitions.
