Product Architecture

Ucloud Cloud Database MySQL High Availability Edition Architecture:

Disaster Recovery Principles:

1> High Availability UDB uses a dual-master architecture, and data synchronization is achieved through Semi-Sync.

2> The UDB Availability Management module monitors the availability of underlying nodes in real time. Once it detects that the Master DB is unavailable, it triggers automatic disaster recovery and VIP migration to the Standby DB to ensure the stable and reliable service of the user's UDB database.

3> For user benefits: single VIP access and seamless application layer switching, where users do not need any manual intervention or configuration changes throughout the entire process.
