Join an EC2 instance to your Amazon Managed Microsoft AD directory

You can seamlessly join an EC2 instance to your Active Directory domain when the instance is launched. For more information, see Seamlessly join a Windows EC2 instance. You can also launch an EC2 instance and join it to an Active Directory domain directly from the Amazon Directory Service console with Amazon Systems Manager Automation.

If you need to manually join an EC2 instance to your Active Directory domain, you must launch the instance in the proper Region and security group or subnet, then join the instance to the domain.

To be able to connect remotely to these instances, you must have IP connectivity to the instances from the network you are connecting from. In most cases, this requires that an internet gateway be attached to your VPC and that the instance has a public IP address.
