Running a database on Kubernetes is closer to the full-ops option, but you do get some benefits in terms of the automation Kubernetes provides to keep the database application running. keyboard_arrow_right. To jump directly to Cassandra specific backup information. In non-production environments that do not have role-based access control enabled, these extra steps are unnecessary but do no harm to have defined, and serve as a best practice example ahead of your eventual production deployments. The headless Cassandra service is used for Cassandra cluster formation and “seed” discovery.
