AWS SNS
Amazon SNS (Simple Notification Service)
Amazon SNS is a fully managed messaging service designed for sending notifications and messages from publishers to subscribers in a highly scalable and cost-effective manner. It supports various communication methods such as email, SMS, and push notifications.
Key Features of Amazon SNS
Publish/Subscribe Model: Enables applications to send messages to multiple subscribers simultaneously.
Flexible Delivery Options: Supports delivery via email, SMS, push notifications, HTTP/S endpoints, and AWS Lambda functions.
High Throughput: Handles large volumes of messages with low latency.
Durable Message Delivery: Provides reliability with retries and redundancy across multiple Availability Zones.
Security: Integrates with IAM policies for access control and encrypts data at rest and in transit.
Fan-Out: Allows a single message to trigger multiple actions through subscriptions to different endpoints.
How Amazon SNS Works
Publisher: An application or service sends messages to an SNS topic.
Topic: An SNS topic acts as a logical access point and message delivery channel.
Subscribers: Applications or users subscribe to the topic to receive messages via their chosen protocol (e.g., email, SMS, HTTP).
Message Delivery: Once published, the message is pushed to all subscribed endpoints in real time.
Amazon SNS is a powerful tool for building event-driven architectures, sending alerts, and enabling cross-application communication.
