## Summary
- 核心主题：IPAM（IP 地址管理）与 Workload VPC 自动化 provisioning
- 问题域：企业级 VPC IP 地址分配的手动干预问题
- 方法/机制：Infoblox NIOS（Grid 架构）、YAML 配置文件定义 VPC 参数、Availability Zone ID（az id）代替 az name
- 结论/价值：消除手动 IP 地址管理，减少错误，支持多 VPC 同时 provisioning，/22 及以上 CIDR 需审批

## Key Claims
- IPAM 自动化消除手动干预，减少人为错误
- Infoblox Grid 架构防止重叠 IP 地址
- 使用 az id 替代 az name 避免可用区命名不一致
- /22 及以下 CIDR 块需要审批流程

## Key Quotes
> "We don't need to worry about IP address. If it's beyond IP address is 22 or greater, then only we need to take the approval."
- Pushka, Principal SRE

> "So we just need to put the information at the right place and everything will work."
- Pushka, Principal SRE
