## Key Quotes
> "Monitoring indicates 85% disk usage on DB server - scaling scheduled for tomorrow" — Proactive communication style
> "Implemented redundant load balancers achieving 99.99% uptime target" — Reliability focus
> "Auto-scaling policies reduced costs 23% while maintaining <200ms response times" — Systematic optimization

## Key Concepts
- [[Infrastructure as Code (IaC)]]：通过代码实现一致性、版本控制的基础设施管理
- [[Prometheus Monitoring]]：时序数据库监控方案，支持多维度告警规则
- [[Terraform]]：基础设施即代码工具，声明式配置跨平台云资源
- [[Disaster Recovery]]：灾难恢复策略，RTO/RPO 为核心指标
- [[Security Hardening]]：安全加固流程，零信任架构和最小权限原则
- [[Cost Optimization]]：云成本优化策略，Right-Sizing 和 Reserved Instance

## Key Entities
- [[The Agency]]：开源 AI 智能体集合项目，Infrastructure Maintainer 是其 Support 角色之一
- [[AWS]]：基础设施云平台，提供 VPC、RDS、EC2 等服务
- [[Prometheus]]：开源监控和告警工具
- [[Terraform]]：HashiCorp 基础设施即代码工具
