EC2 Spot Instance 價錢的上漲趨勢

在「Farewell to the Era of Cheap EC2 Spot Instances」這邊討論了 Amazon EC2spot instance 最近有上漲的趨勢,像是這張應該是從 web console 拉出來 us-east-1t4g.nano 趨勢:

有不少 region 都有類似的情況,尤其是最常用的 us-east-1us-west-2

上個月 Plurk 的朋友也有聊到類似的情況,在 us-east-1 上愈來愈難找到便宜的 spot instance 機器了,當時還在想是不是有什麼大型活動,但文章出來後才發現大家都有遇到類似的情況。

另外在 Hacker News 上面也有討論:「Farewell to the Era of Cheap EC2 Spot Instances (pauley.me)」,裡面是有提到了一些工具可以再更彈性的調整,用更多邏輯改善成本,像是 AutoSpotting - Community Edition 這個專案用 lambda 幫你調整:

The entire logic described above is implemented in a set of Lambda functions deployed using CloudFormation or Terraform stacks that can be installed and configured in just a few minutes.

回頭來看一下目前的情況 (以及猜測 AWS 的策略),如果 spot instance 的常態價錢維持在牌價的六七成,等於是逼你規劃用 Savings Plans 之類的方案,然後讓 spot instance 慢慢退場。

話說回來,接下來不知道會不會有人去告 90% saving 的廣告宣傳...

AWS 推出了 Graviton3 的機種

Amazon EC2 推出了 Graviton3 的機種:「New Graviton3-Based General Purpose (m7g) and Memory-Optimized (r7g) Amazon EC2 Instances」。 第一波只有一般的 m7g 與記憶體型的 r7g,而計算型的 c7g 大家在 Twitter 上猜應該晚點會放出消息。在去年五月就推出了:「AWS 推出 c7g 機種」。 目前只在歐美的 us-east-1、us-east-2、us-west-2 與 eu-west-1 區提供,亞洲目前都還沒有這些機種可以用: M7g and R7g instances are available today in the US East (N. Virginia), US East (Ohio), US West (Oregon),…
