Amazon EC2 推出新的 family type,T3 系列了:「Introducing Amazon EC2 T3 Instances」。

官方宣稱比 T2 系列的機器快 30%:

T3 instances also feature the latest 2.5 GHz Intel Xeon Scalable processors which combined with the AWS Nitro System result in up to a 30% better price to performance improvement over T2 instances.

另外 T3 低階系列的機器 (t3.nanot3.microt3.small) 都是 2 vCPU 了,而且「CPU credits earned per hour」是原來的兩倍,但 t3.mediumt3.large 就跟原來一樣了,而再更大台的 t3.xlarget3.2xlarge 又比較大了... (參考「CPU Credits and Baseline Performance」)

另外是價錢上的差異,T3 的單價反而比 T2 低了一些:以 us-east-1 來看,t3.nano 是 USD$0.0052/hr,而 t2.nano 則是 USD$0.0058/hr,大約是 10% 的差距。

Reserved Instance 也是類似的情況,t3.nano 是 USD$27/y 與 USD$51/3y,t2.nano 則是 USD$29/y 與 USD$57/3y。

這次發佈把台灣團隊常用的區域都納入了,包括了北美的 us-east-1 (北維吉尼亞)、us-west-2 (奧勒崗) 與亞洲的 ap-northeast-1 (東京)、ap-southeast-1 (新加坡):

Amazon EC2 T3 Instances are available immediately in the US East (N. Virginia), US East (Ohio), US West (N. California), US West (Oregon), Canada (Central), Asia Pacific (Singapore), Asia Pacific (Sydney), Asia Pacific (Tokyo), Europe (Frankfurt), Europe (Ireland), Europe (London), and South America (Sao Paulo) AWS Regions.

現有的機器都可以考慮換過去了... 這也是買三年 RI 最好的時機了 XD
