Amazon SNS is a web service provided by AWS. SNS stands for Simple Notification Service, and it manages and delivers the messages or notifications to the users and clients from any cloud platform. In SNS, there are two types of clients, subscribers, and publishers. Publishers produce and send a message to the subscriber instance through the communication channels.

Subscribers receive notification from the publisher over one of the supported protocols such as Amazon SQS, HTTP, and Lambda, etc. Amazon SNS automatically triggers the service and sends an email with a message that “ your EC2 instance is growing” when you are using Auto Scaling. Amazon SNS automatically triggers the service and sends an email with a message that “ your EC2 instance is growing” when you are using Auto Scaling.

Amazon Simple Notification Service (Amazon SNS) is a fully managed messaging service for both application-to-application (A2A) and application-to-person (A2P) communication.

The A2A pub/sub functionality provides topics for high-throughput, push-based, many-to-many messaging between distributed systems, microservices, and event-driven serverless applications. Using Amazon SNS topics, your publisher systems can fan-out messages to a large number of subscriber systems including Amazon SQS queues, AWS Lambda functions, and HTTPS endpoints, for parallel processing, and Amazon Kinesis Data Firehose. The A2P functionality enables you to send messages to users at scale via SMS, mobile push, and email.

Benefits

Modernize and decouple your applications

Amazon SNS enables you to modernize your applications and decouple them into smaller, independent components that are easier to develop, deploy and maintain. Leveraging a pub/sub-event-driven architecture for your application improves performance, reliability, and allows each component to scale independently

Send messages directly to millions of users

Amazon SNS enables you to send messages or notifications directly to users with SMS text messages to over 200 countries, mobile push on Apple, Android, and other platforms or email (SMTP). Amazon SNS provides redundancy across multiple SMS providers and allows you to push mobile notifications using a single endpoint for all platforms.

Reliably deliver messages

Amazon SNS uses a number of strategies that work together to provide message durability. To start, published messages are stored across multiple, geographically separated servers and data centers. If a subscribed endpoint isn’t available, Amazon SNS executes a message delivery retry policy. To preserve any messages that aren’t delivered before the delivery retry policy ends, you can create a dead-letter queue. You can also subscribe to Amazon Kinesis Data Firehose delivery streams to SNS topics, which allows messages to be sent to durable endpoints such as Amazon S3 buckets or Amazon Redshift tables.

Automatically scale your workload

Amazon SNS leverages the proven AWS cloud to dynamically scale with your application. Amazon SNS is a fully managed service, taking care of the heavy lifting related to capacity planning, provisioning, monitoring, and patching. The service is designed to handle high-throughput, busty traffic patterns and enables you to send millions of messages per second.

Ensure accuracy with message ordering and deduplication

Amazon SNS FIFO topics work with Amazon SQS FIFO queues to ensure messages are delivered in a strictly ordered manner and are only processed once (deduplicated). This enables you to maintain consistency when processing transactions across a single or multiple independent services where it’s critical that messages are in the correct order. It also allows you to offload the effort of writing custom code for ordering and message deduplication.

Simplify your architecture with Message Filtering

Amazon SNS helps you simplify your pub/sub messaging architecture by offloading the message filtering logic from your subscriber systems, and message routing logic from your publisher systems. With Amazon SNS message filtering, subscribing endpoints receive only the messages of interest, instead of all messages published to the topic. Amazon Cloud Watch gives visibility into your filtering activity, and AWS Cloud Formation allows you to deploy subscription filter policies in an automated and secure manner.
