A big thanks to the creators of Learn to Build Full-Stack Apps with Serverless and React on AWS. AWS Cognito User Pools vs Identity pool and the various terminologies involved were all very confusing to me. This guild helped me to get my AWS IAM, Cognito, User Pool vs Identity pool concepts clear in a big way.
