Amazon Simple Notification Service (Amazon SNS) is a fast, flexible, fully managed push messaging service. Amazon SNS makes it simple and cost-effective to push to mobile devices such as iPhone, iPad, Android, Kindle Fire, and internet connected smart devices, as well as pushing to other distributed services.

Besides pushing cloud notifications directly to mobile devices, Amazon SNS can also deliver notifications by email, to Amazon Simple Queue Service (SQS) queues, or to any HTTP endpoint.

To prevent messages from being lost, all messages published to Amazon SNS are stored redundantly across multiple availability zones.


Modernize and decouple your applications

Amazon SNS enables you to modernize your applications and decouple them into smaller, independent components that are easier to develop, deploy, and maintain. Leveraging a pub/sub event-driven architecture for your application improves performance, reliability, and allows each component to scale independently.

Reliably deliver messages

Amazon SNS uses a number of strategies that work together to provide message durability. To start, published messages are stored across multiple, geographically-separated servers and data centers. If a subscribed endpoint isn't available, Amazon SNS executes a message delivery retry policy. To preserve any messages that aren't delivered before the delivery retry policy ends, you can create a dead-letter queue. You can also subscribe Amazon Kinesis Data Firehose delivery streams to SNS topics, which allows messages to be sent to durable endpoints such as Amazon S3 buckets or Amazon Redshift tables.

Automatically scale your workload

Amazon SNS leverages the proven Amazon Web Services cloud to dynamically scale with your application. Amazon SNS is a fully managed service, taking care of the heavy lifting related to capacity planning, provisioning, monitoring, and patching. The service is designed to handle high-throughput, bursty traffic patterns and enables you to send millions of messages per second.

Ensure accuracy with message ordering and deduplication

Amazon SNS FIFO topics work with Amazon SQS FIFO queues to ensure messages are delivered in a strictly ordered manner and are only processed once (deduplicated). This enables you to maintain consistency when processing transactions across a single or multiple independent services where it’s critical that messages are in the correct order. It also allows you to offload the effort of writing custom code for ordering and message deduplication.

Simplify your architecture with Message Filtering

Amazon SNS helps you simplify your pub/sub messaging architecture by offloading the message filtering logic from your subscriber systems, and message routing logic from your publisher systems. With Amazon SNS message filtering, subscribing endpoints receive only the messages of interest, instead of all messages published to the topic. Amazon CloudWatch gives visibility into your filtering activity, and Amazon CloudFormation allows you to deploy subscription filter policies in an automated and secure manner.
