Amazon SNS now supports configuring delivery status logging with AWS CloudFormation

[Amazon Simple Notification Service](https://aws.amazon.com/sns/) (Amazon SNS) enables you to log the delivery status of messages sent from your topic to subscribers. Once configured, log entries are sent to Amazon CloudWatch Logs. Logging message delivery status helps you determine whether a message was delivered to an endpoint, what the endpoint response was, and the message dwell time. Now, you can configure your delivery status logging with AWS CloudFormation for new and existing Amazon SNS topics. Amazon SNS is a messaging service for Application-to-Application (A2A) and Application-to-Person (A2P) communication. The A2A functionality provides high-throughput, push-based, many-to-many messaging between distributed systems, microservices, and event-driven serverless applications. These applications include Amazon Simple Queue Service (Amazon SQS), Amazon Kinesis Data Firehose, AWS Lambda, and HTTP/S endpoints. The A2P functionality enables you to communicate with your customers, via mobile text messages (SMS), mobile push notifications, and email notifications. Configuring Amazon SNS delivery status logging with AWS CloudFormation is available in all [AWS Regions](https://aws.amazon.com/about-aws/global-infrastructure/regional-product-services/).
