What is AWS SNS?
Amazon Simple Notification Service (SNS) is a fully-managed pub/sub messaging service provided by AWS that allows developers to communicate messages sent by publishers to a variety of users via different endpoints such as SMS, email, and mobile push. It makes decoupled architectures easier by coordinating notifications in real time.
Getting Started
Create a topic using AWS Console Service > SNS > Topics > Add. Subscribe by an email address or by ARN. verify that you have done so, and then publish the tests messages. Utilize IAM policies to manage access.
Examples of CLI commands: aws sns create-topic –name MyTopic.
Advanced Configurations
You can enable raw message delivery for third-party compatibility as well as message encryption for data. Apply topic policies to access across accounts and CloudWatch for metrics such as publish rate. Connect with EventBridge for larger occasions.
To handle high volumes, you can make delivery retries as well as the redrive policy.
