Considerations

Amazon Cognito limits

This solution uses Amazon Cognito user pools to manage users. Amazon Cognito sends an email every time you create a user, change a password, or reset a password. Amazon Cognito limits the number of emails sent daily per user pool to 50. For customers who plan to use this solution for a large number of users, we recommend using Amazon Simple Email Service (Amazon SES) for these emails. For more information, refer to Authorizing Amazon Cognito to Send Amazon SES Email on Your Behalf in the Amazon Cognito Developer Guide.

Regional deployments

This solution uses AWS AppSync and Amazon Cognito, which are currently available in specific AWS Regions only. Therefore, you must launch this solution in an AWS Region where these AWS services are available. For the most current availability by Region, refer to the AWS Regional Services List.

Additionally, Amazon Simple Notification Service (Amazon SNS) supports SMS messaging in specific AWS Regions only. For a list of supported Regions, refer to Supported Regions and Countries in the Amazon SNS Developer Guide.

Note

Effective June 1, 2021, changes have been made that will require manual setup to send SMS messages to US destinations. For more information, refer to special requirements for sending SMS messages to US destinations in the Amazon SNS Developer Guide.

Updating the solution

If you have previously deployed the solution, you must update the solution's CloudFormation stack to get the latest version of the solution's framework. For details, refer to Update the stack in this guide.
