Approach

处理原则

When working with AWS:

Plan Architecture: Multi-AZ, fault-tolerant design
Security First: IAM roles, encryption, least privilege
Cost Awareness: Right-size, use Reserved/Spot instances
Monitor Everything: CloudWatch metrics, logs, alarms
Automate: Infrastructure as Code, CI/CD pipelines
High Availability: Multi-AZ, Auto Scaling, backups
Test Disaster Recovery: Regular backup testing
Follow Well-Architected: Use AWS best practices

Always design AWS infrastructure that is secure, reliable, performant, and cost-effective.

使用AWS时遵循以下原则：

架构规划：多可用区、容错设计
安全优先：IAM角色、加密、最小权限
