Overview
Huawei Cloud Availability Zone (AZ) capability allows you to deploy a DR architecture for an application at a low cost to prevent service interruptions caused by a single-AZ fault. Application systems can be designed to access resource pools across multiple AZs. They use the cross-AZ data replication and switchover provided by cloud service instances or supported by applications to replicate data, balance loads, and perform failover across AZs. This helps application systems handle failures within specific AZs effectively.
