Amplify Studio questions on workload and production readiness

Good Day Everyone,

Is Amplify studio ready to be used for building production workloads. I have few quick questions with regards to this:

1. Can you manage multiple environments say Dev, STG and Prod
2. Is there any pipeline that can be configured to rollout a deployment in the case of various environments
3. It uses cognito, I would like to integrate with Active Directory does this support.

Cheers..!!
