sns

What problem does it solve?

AWS Simple Notification Service (SNS) provides a managed pub/sub messaging backbone that decouples producers from consumers, enabling scalable notifications and event-driven communication across services and devices.

Core Features & Use Cases

• Topics for publish/subscribe messaging to fan out notifications.
• Subscriptions to Lambda, SQS, HTTP/HTTPS endpoints, Email, SMS, and mobile push.
• Message filtering with attributes to route messages to appropriate subscribers.
• Multi-protocol support enabling simple cross-service and user-facing notifications.

Quick Start

Create a topic, subscribe a recipient, and publish a sample message to verify delivery.
