看到 CloudFront 的產品新聞稿：「Amazon CloudFront announces availability of Embedded Points of Presence」，AWS 在 CloudFront 上端出了 Embedded Points of Presence 服務，看名字就是更彈性的 CDN PoP，不過想知道更細節的東西得去看 FAQs 的部分...
從這段可以看到應該是 AWS 的 appliance，然後放到實體機房裡面提供服務：
These embedded POPs are owned and operated by Amazon and deployed in the last mile of the ISP/MNO networks to avoid capacity bottlenecks in congested networks that connect end viewers to content sources, improving performance.
比較特別的消息是，這個不會額外收費：
Q. Is there a separate charge for using embedded POPs?
No, there is no additional charge for using CloudFront embedded POPs.
另外這個服務會是 opt-in 選擇加入，但不需要額外設定 distribution，而且 CloudFront 會針對有 opt-in 的 distribution 自動混搭：
Embedded POPs are an opt-in capability intended for the delivery of large scale cacheable traffic. Please contact your AWS sales representative to evaluate if embedded POPs are suitable for your workloads.
No, you do not need to create a new distribution specifically for embedded POPs. If your workload is eligible, CloudFront will enable embedded POPs for your existing distribution upon request.
You don't have to choose between CloudFront embedded POPs or CloudFront POPs for content delivery. Once your CloudFront distribution is enabled for embedded POPs, CloudFront's routing system dynamically utilizes both CloudFront POPs and embedded POPs to deliver content, ensuring optimal performance for end users.
下一章「Compliance」的部分有提到 embedded POPs 是不包括在 PCI DSS、HIPAA 以及 SOC 這些 compliance 的，所以也可以回頭看到在提到推薦掛上來的內容，有避開掉敏感服務，主要是以大家都會看到一樣的內容的東西為主：
Embedded POPs are custom built to deliver large scale live-streaming events, video-on-demand (VOD), and game downloads.
看起來有點像是 Netflix 的 Open Connect 或是 Google 的 GGC，讓 ISP 或是 MNO 可以放 cache service 降低對外消耗的流量。
這應該會回到老問題，ISP/MNO 當然是希望 CloudFront 花錢放機器進來，不會是 ISP/MNO 自己申請放，這不是技術問題而是商業問題...
