Amazon Simple Notification Service (SNS) is a highly available, durable, secure, pub/sub service that enables you to decouple microservices, distributed systems, and applications. Amazon SNS provides topics for high-throughput, push-based, many-to-many . Using Amazon SNS topics, your publisher systems can fan out messages to a large number of subscriber endpoints for parallel processing, including Amazon SQS queues, AWS Lambda functions, and HTTP/S webhooks. Additionally, SNS can be used to fan out notifications to end users using mobile push, SMS, and email.
