The Amplify CLI acts as a single source of truth. You install the SDK from there, and using the Amplify API, you can talk to and manage AWS services directly from your code. You don't need to go to the GUI and click through menus - everything is manageable through the Amplify API at the code level. AWS Amplify integrates seamlessly with other services through AWS CloudFormation. Amplify first connects to the cloud for me. Whenever we write down the SDK, it's managed by CloudFormation. CloudFormation still happens on our cloud for your application because everything is updated with the help of cloud automation. Anything we need to change, we just add it to Amplify, and Amplify triggers the CloudFormation templates. Then it logs permission, updates the whole thing, or whatever you need it to ask.
