AWS 在 us-west-2 開 Local Zone

AWS 宣佈 us-west-2 (Oregon) 開 Local Zone,這應該是 AWS 第一次在美國開 Local Zone,上次看到好像是 ap-northeast-1 (Tokyo) 的 Osaka 區:「AWS Now Available from a Local Zone in Los Angeles」。

控制都還是在 us-west-2 的範圍控制,但代碼會是 us-west-2-lax-1a (目前只有一區),之後會開 us-west-2-lax-1b (第二區):

In the fullness of time (as Andy Jassy often says), there could very well be more than one Local Zone in any given geographic area. In 2020, we will open a second one in Los Angeles (us-west-2-lax-1b), and are giving consideration to other locations. We would love to get your advice on locations, so feel free to leave me a comment or two!

剛剛登入進去 VPC 的 Subnets 想要增加看看,沒看到 us-west-2-lax-1a 的選項可以選,看起來還是需要另外申請?

另外算了一下 Oregon (用 Portland 算) 到 Los Angels 的直線距離,大約要 1300km 左右 (比台北到香港還遠不少),光速單趟大約要 6.5ms?這樣對一些應用程式應該是會有感覺...

This Local Zone is designed to provide very low latency (single-digit milliseconds) to applications that are accessed from Los Angeles and other locations in Southern California.

看起來主要還是支援異地的需求...
