Fanout Pattern
The fanout pattern in AWS SNS is a messaging pattern that allows a single published message to be sent to multiple subscribers, making it easy to broadcast information quickly and efficiently. This can be particularly useful when different components of a system are interested in the same event or data but need to process it independently. In the fanout pattern, a message is published to an SNS topic, and each of the subscribers to the topic receives the message. The flexibility of the fanout pattern allows for the addition or removal of subscribers without impacting the publisher. The benefits of using the fanout pattern in AWS SNS include decoupling of components, scalability, and redundancy across message processing.
