# Opt-in Regions
<a name="opt-in-regions"></a>

An opt-in Region is an AWS Region that’s deactivated by default. You can activate opt-in Regions can be activated in the AWS console. For additional information about opt-in Regions and how to activate them, refer to [Managing AWS Regions](https://docs.aws.amazon.com/general/latest/gr/rande-manage.html) in the *AWS General Reference guide*.

This solution supports four opt-in Regions:
+ Asia Pacific (Hong Kong)
+ Middle East (Bahrain)
+ Africa (Cape Town)
+ Europe (Milan)

  When launched in an opt-in Region, this solution creates an S3 logging bucket for CloudFront in the US East (N. Virginia) Region. This is because CloudFront doesn’t deliver access logs to buckets in the supported opt-in Regions. For more information about S3 buckets, refer to [Choosing an Amazon S3 bucket for your standard logs](https://docs.aws.amazon.com/AmazonCloudFront/latest/DeveloperGuide/AccessLogs.html#access-logs-choosing-s3-bucket) in the *Amazon CloudFront Developer Guide*.

To deploy in an opt-in Region, the S3 bucket(s) that you provide for the **Source Buckets** parameter must be in the same Region where you launch the CloudFormation template.
