The Multi-Cloud DR Playbook: Architecture Patterns for Cross-Cloud Database Resilience

Cloud outages are no longer edge cases. For enterprises running mission-critical databases, regional redundancy inside one cloud is not enough when the cloud provider itself becomes the failure domain.

This eBook explains how to design multi-cloud disaster recovery for database workloads, with practical guidance for reducing single-cloud risk, meeting stricter resilience expectations, and choosing the right cross-cloud architecture.

Inside, you’ll learn:

• Why single-cloud database architectures remain vulnerable even with multi-AZ or multi-region setups
• How OceanBase Cloud enables managed cross-cloud disaster recovery across providers
• The difference between cross-cloud active-active and primary-standby architectures
• How hot standby, warm standby, and cold backup modes compare across RPO, RTO, cost, and network complexity
• How global endpoint routing helps applications fail over without changing connection strings
• Where multi-cloud DR can reduce operational cost compared with DIY replication, CDC tooling, and manual runbooks.
• A practical decision framework for matching your DR architecture to business continuity, compliance, and budget requirements
