What is Amazon SNS (Simple Notification Service)?

Amazon SNS (Simple Notification Service) is a push notification service from AWS for sending messages to large numbers of users. With SNS, you can send push notifications to mobile devices, email addresses and other distributed services. SNS is what is known as a distributed publish-subscribe system. Publishers send messages to SNS, which in turn pushes them to subscribers.

SNS supports a number of protocols, including:

• Amazon Kinesis Data Firehose

• Amazon SQS

• AWS Lambda

• HTTP

• Email

• Mobile push notifications

• Short message service (SMS)

SNS employs a number of strategies to ensure message durability. First, it stores published messages across multiple servers and data centers, which are geographically separated. It also executes a delivery retry policy when subscribed endpoints are not available, and it allows you to create a dead-letter queue to preserve messages that don't get delivered.

SNS is one of two messaging services that AWS offers, with the other being Amazon Simple Queue Service (SQS).
