aws sns subcommand [options]

aws sns is the AWS CLI interface for Amazon Simple Notification Service (SNS), a fully managed messaging service for application-to-application (A2A) and application-to-person (A2P) communication.
SNS enables pub/sub messaging where publishers send messages to topics, and subscribers receive notifications via protocols including HTTP/HTTPS, email, SMS, SQS, Lambda, and mobile push notifications.

Email subscriptions require confirmation by the recipient before they receive messages. SMS messages have regional restrictions and may require spending limit increases. Message size is limited to 256KB for standard topics. FIFO topics require compatible SQS FIFO queue subscribers.

Amazon SNS launched in April 2010 as a push notification service. It has evolved from simple pub/sub messaging to support mobile push notifications, SMS, and advanced features like message filtering, dead-letter queues, and FIFO topics.
