## [2026-04-25] ingest | CTP Topic 63 Optimise resource cost using automation

- Summary: 使用自动化手段优化 AWS 云资源成本——五大策略:批准区域标准化、Graviton ARM 实例选型(比 Intel 便宜 20-25%)、承诺计划(1年 40% / 3年 64% 折扣)、GP2→GP3 存储优化(节省 20%)、基于标签的 EC2/RDS 自动化调度(每天只运行 10 小时可节省 70% 成本)
|
||||
- Concepts created: 无(已存在的 [[Savings-Plans]] 涵盖承诺计划;Graviton/RightSizing 等概念在本 wiki 中出现频次不足以独立建页)

- Notes: Pushka 演示 Terraform Scheduler 模块配置(`auto_shutdown = yes` 标签);无内容冲突
