 ## Recommended instance types and storage
 
 - Instance types: to gain better performance, the following is recommended:
-    - PD nodes: `c5.xlarge`
-    - TiDB nodes: `c5.4xlarge`
-    - TiKV or TiFlash nodes: `m5.4xlarge`
+    - PD nodes: `c7g.xlarge`
+    - TiDB nodes: `c7g.4xlarge`
+    - TiKV or TiFlash nodes: `m7g.4xlarge`
 - Storage: Because AWS supports the [EBS `gp3`](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/general-purpose.html#gp3-ebs-volume-type) volume type, it is recommended to use EBS `gp3`. For `gp3` provisioning, the following is recommended:
     - TiKV: 400 MiB/s, 4000 IOPS
     - TiFlash: 625 MiB/s, 6000 IOPS

 ## 推荐机型及存储
 
 - 推荐机型：出于性能考虑，推荐：
-    - PD 所在节点：`c5.xlarge`
-    - TiDB 所在节点：`c5.4xlarge`
-    - TiKV 或 TiFlash 所在节点：`m5.4xlarge`
+    - PD 所在节点：`c7g.xlarge`
+    - TiDB 所在节点：`c7g.4xlarge`
+    - TiKV 或 TiFlash 所在节点：`m7g.4xlarge`
 - 推荐存储：因为 AWS 目前已经支持 [EBS gp3](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/general-purpose.html#gp3-ebs-volume-type) 卷类型，建议使用 EBS gp3 卷类型。对于 gp3 配置，推荐：
     - TiKV：400 MiB/s 与 4000 IOPS
     - TiFlash：625 MiB/s 与 6000 IOPS
