# Global vs Regional features
<a name="multi-region-global-region-features"></a>

When you add an AWS Region to your directory using multi-Region replication, Directory Service enhances the scope of all features so that they become Region-aware. These features are listed on various tabs of the details page that appears when you choose the ID of a directory in the Directory Service console. This means that all features are enabled, configured, or managed based on the Region that you select in the **Multi-Region replication** section of the console. Changes you make to features in each Region are either applied globally or per Region.

Multi-Region replication is only supported for the **Enterprise Edition** of AWS Managed Microsoft AD.

## Global features

Any changes that you make to global features while the [Primary Region](multi-region-global-primary-additional.md#multi-region-primary) is selected will be applied across all Regions.

You can identify the features that are used globally on the **Directory details** page because they display **Applied to all replicated Regions** next to them. Alternatively, if you selected another Region in the list that is not the primary Region, you can identify the globally used features because they display **Inherited from primary Region**.

## Regional features

Any changes that you make to a feature in an [Additional Region](multi-region-global-primary-additional.md#multi-region-additional) will be applied only to that Region.

You can identify the features that are Regional on the **Directory details** page because they do ***not*** display **Applied to all replicated Regions** or **Inherited from primary Region** next to them.
