- Amazon Simple Notification Service (Amazon SNS) is a managed service that delivers messages from publishers to subscribers (producers and consumers).
- Publishers communicate asynchronously with subscribers by sending messages to a topic, a logical access point and communication channel.
- Clients can subscribe to the SNS topic and receive published messages using a supported endpoint type, such as Amazon Kinesis Data Firehose, Amazon SQS, AWS Lambda, HTTP, email, mobile push notifications, and mobile text messages (SMS).
