Service Resilience

Huawei Cloud WAF is deployed in data centers that are active around the world. Data centers in two cities are deployed as disaster recovery center for each other. If a data center in city A is down, the data center in city B automatically takes over the job and serves your applications and data in compliance with the regulations to ensure service continuity. To minimize the service interruptions caused by hardware failures, natural disasters, or other disastrous events, Huawei Cloud WAF provides a DR plan:

If a fault occurs, the five-level reliability architecture of WAF supports different levels of reliability. Therefore, WAF has high availability, fault tolerance, and scalability.

Huawei Cloud WAF is available worldwide and is deployed in multiple AZs. With management planes, engines, and other components of WAF deployed in active/standby or cluster mode, WAF itself is stable enough.
