Amazon SNS now integrates with AWS Lambda: Invoke Lambda functions through SNS notifications

You can now invoke AWS Lambda functions by publishing notifications in Amazon SNS. This makes it easy to customize notifications before sending them to mobile devices or other destinations. Applications and AWS services that already send SNS notifications, such as Amazon CloudWatch, can now integrate with AWS Lambda through push notifications, without provisioning or managing infrastructure. You can also use SNS notification delivery to an AWS Lambda function as a way to publish to other AWS services such as Amazon Kinesis or Amazon S3. To learn more, visit our documentation.
