AWS Simple Notification Service (SNS)
Fully managed pub/sub messaging for microservices, distributed systems, and serverless applications.
Overview
Amazon SNS is a managed service that provides message delivery from publishers to subscribers (also known as producers and consumers). Publishers communicate asynchronously with subscribers by sending messages to a topic, which is a logical access point and communication channel. Subscribers like AWS Lambda, SQS queues, and HTTP/S endpoints can consume messages published to a topic.
