CloudFront 東京加到七個 Edge...

在「Amazon CloudFront announces six new Edge Locations, adding two more in Tokyo, JP, and its first location in Perth, AU」這邊看到 Amazon CloudFront 在東京直接加兩個 Edge,變成七個 Edge 了:

Amazon CloudFront announces six new Edge Locations that are now part of its global network. These six new Edge Locations are located in the following cities:

Perth, Australia; Chennai, India; Rio De Janeiro, Brazil; Los Angeles, California; and two additional Edge Locations in Tokyo, Japan.

再加上大阪還有一個 Edge,日本的量這麼大喔?會跟 Regional Edge 有關嗎...

CloudFront 的第 100 個 PoP

昨天還在猜 Amazon CloudFront 的第 100 個 PoP 會在哪裡 (「CloudFront 第 99 個 PoP」),結果今天就開獎了... 是在東京擴充第五個 PoP (加上大阪之後是日本的第六個 PoP):「Amazon CloudFront now has 100 Points of Presence with the launch of its fifth Edge Location in Tokyo, Japan.」。

Our 100th Point of Presence (POP) is also the fifth Edge Location in Tokyo, and our sixth in Japan.

東京擴張的好快... Anyway,這是現狀:

可以看到美國中部的普及率還是偏低,另外缺了非洲... 如果 CloudFront 繼續擴張應該會看到消息。(美國的 PoP 一直有看到在加的消息,比起前幾年是好不少,不過看起來增加的速度還是沒有比其他地區的勤...)

Cloudflare 也能在各端點跑 JavaScript 了

類似於 AWS 先前推出的 Using CloudFront with Lambda@Edge (參考「在 CloudFront 的 edge 上跑 Lambda」以及「Lambda@Edge 的 GA」),Cloudflare 也推出了類似的功能:「Introducing Cloudflare Workers: Run Javascript Service Workers at the Edge」、「Code Everywhere: Why We Built Cloudflare Workers」。

整個系統是架構在 Chrome V8 上,尤其是安全性的部分是 Cloudflare 的人頗讚賞的重點:

Security: The V8 JavaScript engine is arguably the most scrutinized code sandbox in the history of computing, and the Chrome security team is one of the best in the world. Moreover, Google pays massive bug bounties to anyone who can find a vulnerability. (That said, we have added additional layers of our own sandboxing on top of V8.)

比較不一樣的地方在於 Cloudflare 拿 Service Worker API 來設計他們的架構,AWS 則是自己幹了一套出來...

然後現在還沒給出價錢,也還沒完全開放使用... 想要玩的人需要申請 beta。

KeyCDN 的台灣 PoP...

GCP 推出 Standard Tier 後,KeyCDN 就利用台灣的 GCP 機房建立了 PoP:「KeyCDN Launches New POP in Taiwan」。

GCP 在台灣的 Standard Tier 價錢是:

Source geolocation of traffic0-10 TB10-150 TB150-500 TB
From Asia$0.11$0.075$0.07

KeyCDN 亞洲區頻寬的價錢則是 USD$0.12/GB,加上機器費用,有機會不虧?

CloudFlare 總算記得要加美國的點了...

CloudFlare 一直加海外的點,在東南亞加到平均 latency 比美國低... 這有點不太像話 XD 總算是記得要加強美國的 latency 了:「Hello, Colorado! CloudFlare's 82nd Data Center is Live in Denver」。

這次加在丹佛剛好是目前美國的點裡面最弱的一環:先前離 CloudFlare 最近的機房應該是 Phoenix 或是 Dallas,都大約在 600km 左右,latency,而網路也不會直線連接,所以這次加上去後的改善很明顯:


Denver joins CloudFlare's existing United States data centers in Ashburn, Chicago, Dallas, Los Angeles, Miami, Minneapolis, Phoenix, San Jose, and Seattle. In the continued pursuit of faster performance, we have data centers at another ten North American cities in the works.


Our week of expansion isn't done. Tomorrow, we head to one of the world's largest cities.
