Our primary transport mechanism for events. One SNS topic carries a specific event type and n-number of subscribers (usually a Lambda) may subscribe to that event.

Amazon SNS is used for push notification to push notifications of the occurrence of different events during operations of our computing resources on AWS cloud.

We use SNS for platform-agnostic mobile push message handling, essentially to avoid dealing with APNS ourselves.

I mainly use it for the infrastructure notifications and alarms of zerotoherojs.com ’s learning dashboards.

SNS is at the core of our messaging - we use the fan out pattern.
