Connecting AWS AD to Azure AD

We are looking in starting to use AD in our office, the setup would be:

• On premise AD server for work stations
• Azure AD to support Office 365
• AWS AD to support AD on our servers

Connecting on premise to Azure is fine, but is there a way to connect the Azure AD to the Amazon AD? The Azure needs to be the master AD where all users are managed.

Is such thing possible?

Are you using AzureAD or just hosting a domain controller in azure?

If its a normal Domain controller then you can just use the AWS domain connector to link them all together, having said that I think best practise would be to have your on premise AD as primary and then use LDAP/Connectors to export changes to Azure and AWS.
