What is Amazon SNS?
Amazon Simple Notification Service (SNS) is a fully managed publish/subscribe messaging service from AWS. It lets applications send messages to multiple subscribers at once, supporting both application-to-application (A2A) delivery to endpoints like AWS Lambda and Amazon SQS, and application-to-person (A2P) delivery through SMS, mobile push, and email. SNS integrates with more than 60 AWS services and is commonly used to decouple microservices and fan out event notifications.
The service offers standard topics for high throughput delivery and FIFO topics for strict message ordering with deduplication. Features include message filtering, batching, archiving and replay, dead letter queues, and encryption with AWS KMS. Pricing is usage based with a permanent free tier covering the first million requests each month.
