Amazon Simple Notification Service (SNS) is a message delivery service provided by Amazon that delivers messages from a publisher to a subscriber. It uses the publish-subscribe model to deliver these messages, where a publisher sends a message to a topic, which is then delivered to all of its subscriber endpoints. Since the publishers and subscribers don’t need to know about each other, Amazon SNS decouples the components of a distributed system and delivers messages between them.
In Amazon SNS, a topic is a communication channel that receives messages from a publisher and delivers them to all available subscriber endpoints.
