Overview

  • Amazon Simple Notification Service
    • Coordinates and manages the delivery or sending of messages to subscribing endpoints or clients.
  • Publishers
    • Communicate asynchronously with subscribers by producing and sending a message to a topic
  • Topic
    • A logical access point and communication channel.
  • Subscribers (web servers, email addresses, Amazon SQS queues, AWS Lambda functions)
    • Consume or receive the message or notification over one of the supported protocols (Amazon SQS, HTTP/S, email, SMS, Lambda) when they are subscribed to the topic.

SNS + SQS Fanout

  • The "fanout" scenario is when an Amazon SNS message is sent to a topic and then replicated and pushed to multiple Amazon SQS queues, HTTP endpoints, or email addresses.
  • This allows for parallel asynchronous processing.

Mobile Push

  • With Amazon SNS, you have the ability to send push notification messages directly to apps on mobile devices. Push notification messages sent to a mobile endpoint can appear in the mobile app as message alerts, badge updates, or even sound alerts.
