Simple Notification Service in AWS | SNS

Amazon Simple Notification Service (SNS) is a fully managed messaging service for both system-to-system and app-to-person (A2P) communication.
It enables you to communicate between systems through publish/subscribe (pub/sub) patterns that enable messaging between decoupled micro service applications or to communicate directly to users via SMS, mobile push and email.
It provides developers with the highly scalable, cost-effective, and flexible capability to publish messages from an application and sends them to other applications.
It is a way of sending messages. When you are using Auto Scaling, it triggers an SNS service which will email you that "your EC2 instance is growing".
The system-to-system pub/sub functionality provides topics for high-throughput, push-based, many-to-many messaging.
Using Amazon SNS topics, your publisher systems can fan-out messages to a large number of subscriber systems or customer endpoints including Amazon SQS queues, AWS Lambda functions and HTTP/S, for parallel processing.
The A2P messaging functionality enables you to send messages to users at scale using either a pub/sub pattern or direct-publish messages using a single API.
SNS is most useful for sending notifications of various events that happen in your AWS-hosted applications and for distributing information between different services in a micro service-oriented infrastructure.

Benefits of SNS:
Modernize and decouple your application
Reliably deliver messages
Fan-out messages directly to millions of users
Automatically scale your workload
