Engineering teams moving from traditional VMs to Kubernetes face the lack of reliability in running databases like MySQL and MariaDB. With complex production needs necessitating high availability and automated backups, Kubernetes operators become essential. One such migration case highlighted the successful use of the Crunchy Postgres Operator for PostgreSQL, demonstrating its effectiveness. However, the transition for MariaDB and MySQL raised challenges, specifically needing high availability, cloud backup support, and a smooth restore process, underscoring the complexities when selecting the appropriate operator for production-grade database management.
One of the final boss-level challenges for engineering teams transitioning to Kubernetes is reliably running production databases such as MySQL and MariaDB.
When migrating databases like PostgreSQL, the Crunchy Postgres Operator has proven to be a reliable solution that meets production-grade requirements.
