Use Case 6: Share your directory to seamlessly join Amazon EC2 instances
to a domain across Amazon accounts
Sharing your directory across multiple Amazon accounts enables you to manage Amazon 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 Amazon
account and from any Amazon VPC within an
Amazon 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
Amazon Managed Microsoft AD directory.
When you share your Amazon Managed Microsoft AD directory with another Amazon account, you can use the
Amazon EC2 console or Amazon Systems Manager to
seamlessly join your instances from any Amazon VPC within the account and Amazon Region. You
can quickly deploy your directory-aware workloads on EC2 instances by eliminating the need to
manually join your instances to a domain or to deploy directories in each account and VPC. For
more information, see Share your directory.
