title: Can the AWS Cognito Id of one Region be used for the Application running at another Region
body: <p>I have an AWS application running in the Singapore region (it includes EC2, RDS and S3 services).</p>
  
  <p>However the AWS Cognito service is available only in US East (N. Virginia) and EU (Ireland). So I configured Cognito at US East.</p>
  
  <p>Now, can I use the Cognito "Identity Pool Id" of the US East region with the AWS web server in Singapore region?</p>
