Join an EC2 instance to your AD Connector directory - Amazon Directory Service
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China.

Join an EC2 instance to your AD Connector directory

You can seamlessly join an EC2 instance to your directory domain when the instance is launched using Amazon Systems Manager. For more information, see Seamlessly joining a Windows instance to an Amazon Directory Service domain in the Amazon EC2 User Guide for Windows Instances.

If you need to manually join an EC2 instance to your 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.


Once you join an instance to your self-managed Active Directory (on-premises), the instance communicates directly with your Active Directory and bypasses AD Connector.
