Using Amazon SNS for application-to-application messaging
Amazon SNS simplifies application-to-application (A2A) messaging by separating publishers from subscribers, which supports microservices, distributed systems, and serverless applications. Messages are sent to Amazon SNS topics, where they can be filtered and delivered to subscribers like Lambda, Amazon SQS, or HTTP endpoints. If delivery fails, the messages are stored in a dead-letter queue for further analysis or reprocessing.
