Use Case 6: Share your directory to seamlessly join Amazon EC2 instances to a domain across AWS accounts

Sharing your directory across multiple AWS accounts enables you to manage AWS services such as Amazon EC2 easily without the need to operate a directory for each account and each VPC. You can use your directory from any AWS account and from any Amazon VPC within an AWS Region. This capability makes it easier and more cost effective to manage directory-aware workloads with a single directory across accounts and VPCs. For example, you can now manage your Windows workloads deployed in EC2 instances across multiple accounts and VPCs easily by using a single AWS Managed Microsoft AD directory.

When you share your AWS Managed Microsoft AD directory with another AWS account, you can use the Amazon EC2 console or AWS Systems Manager to seamlessly join your instances from any Amazon VPC within the account and AWS Region. 您可以消除手动将实例加入域或者在各个账户和 VPC 中部署目录的需求,从而在 EC2 实例上快速部署可感知目录的工作负载。有关更多信息,请参阅 共享您的目录.
