Best solution to connect to active directory hosted in EC2 Instance

Hi I am trying to build automation to manage active directory users, groups, and group memberships. We have multiple OU. Active directory is hosted in an EC2 instance in the same account.

I am planning to build FastAPI-Python based automation deployed in a docker container in the same AWS account where the active directory is hosted in an EC2 instance. Please advise on what is the best practice/approach to develop a solution for the above requirement.
