Amazon EC2 推出 r6a 的機種

Amazon EC2 推出了 r6a (AMD) 的機種:「New – Amazon EC2 R6a Instances Powered by 3rd Gen AMD EPYC Processors for Memory-Intensive Workloads」。

看了一下美東的價錢,r6ar5a 貴了一點點,其中 r6a.24xlarge 是 US$5.4432/hour,而 r5a.24xlarge 則是 US$5.424/hour。

官方宣稱與 r5a 相比有 35% 的 C/P 值改善:

Up to 35 percent higher price performance per vCPU versus comparable R5a instances

然後可以提供更大的機器,之前 r5a 的最大台機器是 r5a.24xlarge (96 vCPU + 768GB RAM),但 r6a 則是拉到了 r6a.48xlarge 或是 r6a.metal (192 vCPU + 1536GB RAM)。

不過目前看起來支援的地區還有限,目前工作用到的 ap-southeast-1 看起來還要再等一下:

You can launch R6a instances today in the AWS US East (N. Virginia, Ohio), US West (Oregon), Asia Pacific (Mumbai) and Europe (Frankfurt, Ireland) as On-Demand, Spot, and Reserved Instances or as part of a Savings Plan.
