2.5 SNS: Push Notifications
While queues are good for processing data, push notifications are great for broadcasting. Using SNS (Simple Notification Service) Topics, you can send a message to multiple subscribers at once. You can also use mobile device notifications to send the same message to phones. In this lesson, we are going to use SNS to create messages with a web interface and forward them to SQS so they can be processed by the consumer we created in the last lesson.
