Amazon Simple Notification Service (Amazon SNS) has introduced additional usage metrics in Amazon CloudWatch for the following service quotas: ‘Topics per Account’, ‘Filter Policies per Account’, and ‘Pending Subscriptions per Account’. Under the ‘AWS/Usage’ namespace, you can now view the ‘ApproximateNumberOfTopics', 'ApproximateNumberOfFilterPolicies', and 'ApproximateNumberOfPendingSubscriptions' metrics to monitor your usage of these Amazon SNS resources. Moreover, using AWS Service Quotas, you can also view your utilization metrics per quota, and create Amazon CloudWatch alarms to notify you when your utilization of a given quota exceeds your configurable threshold. This enables you to more precisely adapt your utilization of Amazon SNS, based on your applied quotas.

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 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.

The new Amazon SNS usage metrics are now available in all AWS Regions, at no additional cost.
