Amazon Cognito Identity lists the region where Cognito is available. You can use AWS Global Infrasturcture to determine the nearest region where Cognito is available.

Nearest Cognito availability is in:

  • ap-south-1 (Asia-Pacific Mumbai)
  • ap-northeast-2 (Asia-Pacific Seoul)
  • ap-northeast-1 (Asia-Pacific Tokyo)

Or use a third party tool like CloudPing to find the region nearest to you based on latency.

使用AWS Cognito时,选择最近的区域不是必须的,因为主应用程序流中与Cognito的交互不常见。 Cognito主要涉及登录流程,您通常可以接受最多几百毫秒的延迟。

无论如何,由于减少延迟效果更好,您可以根据AWS Inter-Region Latency结果选择以下区域(按顺序推荐)。

  1. ap-south-1(亚太孟买)
  2. ap-northeast-1(东京亚太地区)
