Aws Sns articles
AWS SNS (Amazon Simple Notification Service) is a highly available, durable, secure, fully managed pub/sub messaging service that enables you to decouple microservices, distributed systems, and serverless applications. SNS provides topics for high-throughput, push-based, many-to-many messaging. It enables applications to send time-critical messages to multiple subscribers through a “push” mechanism, eliminating the need to periodically check or “poll” for updates. SNS can be used to fan out notifications to end users via mobile push, SMS, and email.
