Introduction

AWS SNS (Simple Notification Service) is a fully managed messaging service provided by Amazon Web Services (AWS). It enables developers to send push notifications, SMS messages, and email messages to subscribers. SNS follows a publish-subscribe messaging pattern, where messages are sent to topics and then delivered to subscribers who have expressed interest in receiving messages from those topics. Key features of AWS SNS include:
  1. Topic-based messaging: SNS allows you to create topics, which act as communication channels for sending messages. Publishers send messages to topics, and subscribers receive messages from topics they have subscribed to.
  2. Multiple message protocols: SNS supports multiple message protocols, including HTTP/HTTPS, email, SMS, SQS (Simple Queue Service), Lambda functions, mobile push notifications, and more. This flexibility allows you to choose the most appropriate protocol for delivering messages to your subscribers.
