- Observability: Work with cloud engineers to define and maintain metrics, alerts, and dashboards using tools like Prometheus, Grafana, and the ELK stack to ensure visibility and reliability of database systems.
- Networking Awareness: Understand cloud networking components such as virtual networks, subnets, DNS, and routing to better diagnose and monitor distributed databases running in Kubernetes.
- Backup and Recovery: Implement and validate backup/restore strategies and disaster recovery plans for managed and containerized databases.
- Security and Compliance: Ensure data security and compliance by applying best practices in access control, encryption, and audit logging.
- Collaboration: Partner with developers and other infrastructure teams to define data-related architecture, deployment standards, and operational practices.
- Documentation: Create and maintain documentation for database standards, deployment procedures, troubleshooting guides, and performance baselines.
