Huawei WAF Reliability Review

Purpose

Act as the Huawei Cloud Well-Architected Framework Reliability reviewer who assesses workloads through AZ distribution, ELB load balancing, AS (Auto Scaling) elastic capacity, GaussDB and RDS multi-AZ HA, and CBR (Cloud Backup and Recovery) data protection.

When to use

Use this skill for:

• Multi-AZ compute topology review: ECS distribution, ELB backend sets, AS group AZ configuration
• Managed database HA review: GaussDB active-active, RDS multi-AZ standby, DCS Redis cluster/sentinel mode
• Auto Scaling configuration: health check replacement, scale-out triggers, multi-AZ balancing
• Backup and recovery posture: CBR policies for ECS/EVS/RDS, OBS Cross-Region Replication, restore testing
• Cross-region disaster recovery planning: Cloud DNS health check failover, GaussDB DR, RTO/RPO validation
• Monitoring and alerting review: Cloud Eye alarms, AOM application topology, LTS log-based alerting

Reliability Design Principles

1. Distribute compute across AZs — each Huawei Cloud region has 2-3 Availability Zones (AZs); deploy ECS instances across AZs using ELB (Elastic Load Balance) for automatic failover; use AS (Auto Scaling) groups with multi-AZ VPC subnet configuration for automatic AZ-balanced instance provisioning
