Two-Location Three-Center Disaster Recovery Solution

Financial-Grade High Availability: Provides disaster recovery protection against center-level & city-level failures to ensure the security and reliability of business, and meet the national standards for financial-grade disaster recovery. In the event of a primary cluster failure, the standby cluster can perform seamless and rapid failover with zero data loss, taking over production services without interruption.

High Performance:Compared with logical log synchronization, physical log synchronization can improve performance by 10 times; accelerates ultra-long-distance data transmission between different locations, achieving low latency for cross-regional data synchronization.

High Reliability:Employs a multi-level majority consistency protocol to prevent split-brain scenarios under various conditions; Automatic cluster self-healing after various failures are recovered, with full-process automatic disaster recovery management.

Low Cost: Features a single data synchronization link between center clusters, enabling efficient utilization of center-level network resources. Cross-center data replication has minimal impact on production services.

Advanced Architecture: Decouples database sub-clusters across centers with isolated failure domains to prevent global network failures.

Within the center: RPO = 0, RTO < 8s

Between centers: RPO = 0, RTO < 60s

Between remote centers: RPO as low as sub-second level, RTO = minute level
