AWS re:Invent 总结： 1. AI 无处不在 2. Serverless 继续进化 3. 多云策略已成趋势 4. 安全是每个人的责任 最大感受：云计算还远没到天花板。

GCP 的 Cloud Run 真的很適合小團隊。不用管伺服器，按流量計費，部署超簡單。

Passed all three AWS certifications this month. My brain is 90% cloud architecture diagrams now.

Cloud costs dropped 60% after we right-sized our EC2 instances. We were running t3.2xlarge for a cron job that runs once a day.

Edge computing is not replacing the cloud. It's extending it. Different tools for different problems.

云原生安全三板斧：网络隔离 + 最小权限 + 日志审计。听起来简单，做到位的团队不多。

Serverless is amazing until you get the bill for 50 million Lambda invocations. Know your workload patterns.

Serverless 的冷啟動問題在 GCP 上改善了很多。Cloud Functions 2nd gen 啟動速度快了三倍。

インフラコストの見える化をしたら、不要なリソースが全体の25%もあった。定期的な棚卸しは大事。
