Amazon Cognito user pool options

The following sections refer to CloudFormation quick-create links or quick-create URLs. A quick-create URL takes you to a Create Stack Wizard where you provide quick-create stack template inputs and deploy the stack. For more information about CloudFormation quick-create stacks, see Creating quick-create links for stacks in the Amazon CloudFormation User Guide.

To maintain an Amazon Cognito user pool that you can use with multiple Amazon ParallelCluster UI (PCUI) instances, consider the following options:

  • Use an existing PCUI instance that links to an Amazon Cognito user pool created from a nested CloudFormation stack. This is what is created when you deploy the PCUI by using the quick-create link and keep all Amazon Cognito parameters blank.

  • First, deploy a standalone Amazon Cognito user pool. Then, deploy a new PCUI instance that's linked to the standalone Amazon Cognito user pool that you just deployed. This way, you separate the Amazon Cognito deployment from the PCUI deployment. Note that non-nested PCUI CloudFormation stacks are easier to update.
