云基础设施脆弱性暴露 工程师回归裸金属
文章指出云并非抽象无重力的存在，而是由墙体、冷却管道和电缆构成的实体建筑。去年 5 月单个 AWS 数据中心过热，导致 Coinbase 宕机、Cloudflare 脚本笔误令数千网站不可见，暴露了现代互联网对少数超大规模供应商的脆弱依赖。作者认为业界正为集中化付出代价，部分资深工程师开始悄然回归裸金属部署。

3 0 1 3 Save Share We have spent the last decade convincing ourselves that the cloud is a magical, weightless place. But it isn't. The cloud is a building. It has walls, cooling pipes, and power cables. And sometimes, that building gets too hot.
When a single AWS data center overheated last May, it didn't just take down some servers. It exposed the terrifying fragility of the modern internet. A broken air conditioner in Virginia meant Coinbase went dark, and a single typo in a Cloudflare script made thousands of websites invisible.
We traded the messy, decentralized web for the convenience of a few massive providers. Now, we are paying the price. This is a story about the hidden economics of the cloud, the illusion of resilience, and why the smartest engineers are quietly moving back to bare metal.
