Fault Recovery

DSC fault recovery:
- DSC provides multiple physically independent and isolated AZs that are connected through networks with low latency, high throughput, and high redundancy.
- With AZs, DSC can automatically migrate faulty applications and databases between AZs without interrupting services.
- Compared with traditional single or multiple data center infrastructures, AZs provide higher availability, fault tolerance, and scalability.
API Data Security Protection fault recovery:
- API Data Security Protection supports dual-system hot backup for high availability. When the active device fails, an active/standby switchover is automatically triggered, making the original active device the standby device, thus improving system stability.
- The watchdog monitors service status in real-time and promptly starts the process if the service is abnormal.
- The bypass emergency escape mechanism transparently transmits traffic, ensuring service availability.
- OBS configuration backup and restoration are supported, enabling quick restoration of configuration information in case of a fault.
