AWS i3 与 i2 实例,它们的性能有何不同?
AWS i3 vs i2 instances , what differenctiates their performance?
参考AWS中关于AWS i2实例和i3的区别的post,它本质上是在Intel E5-2686 v4(Broadwell)处理器上使用Amazon Linux AMI,那么究竟是什么使得如果规格相同,i2 和 i3 实例之间的性能差异?
来自Previous Generation Instances:
Compared to I2 instances, I3 instances have over 4x higher I/O performance, over 2x higher disk throughput and 18% more SSD per CPU. I3 instances offer Non-Volatile Memory Express (NVMe) based SSDs offering lower disk latencies than I2. I3 offers the lowest price per read IOPS of all EC2 instances.
- 较新的英特尔至强处理器
- 每个实例更好的存储空间
- 高性能 NVMe 实例存储
- ENA 支持
- 容量更大 (16.xlarge),存储空间高达 15.2 TB
- 每 GB 实例存储的更优惠价格
- 每 IOPS 最优价格
