Amazon SNS enhances cross-Region delivery capabilities

We're excited to announce that Amazon Simple Notification Service (Amazon SNS) has expanded its cross-Region delivery capabilities, providing more flexibility for customers using opt-in Regions. This update brings three improvements:

1. Amazon SNS to Amazon SQS delivery between opt-in Regions: You can now deliver messages from an Amazon SNS topic in one opt-in Region to an Amazon SQS queue in another opt-in Region.
2. Amazon SNS to AWS Lambda delivery between opt-in Regions: Message delivery from an Amazon SNS topic in one opt-in Region to an AWS Lambda function in another opt-in Region is now supported.
3. Amazon SNS to AWS Lambda delivery from default to opt-in Regions: You can now deliver messages from an Amazon SNS topic in a default-enabled Region to an AWS Lambda function in an opt-in Region.

These enhancements provide greater flexibility in designing distributed systems across AWS Regions, making it easier to leverage opt-in Regions in your architectures.

To use these new capabilities, ensure that you've enabled the required opt-in Regions for your account. When configuring cross-region subscriptions involving opt-in Regions, remember to use the Region-specific service principal (sns.<opt-in-region>.amazonaws.com) in your resource policies.

For more information on working with opt-in Regions refer to AWS Account Management documentation. To learn more about Amazon SNS cross-Region deliveries, please refer to Amazon SNS documentation.
