AWS SNS (Explained 2022)

In this blog post, we will be explaining what AWS SNS is and how it works. We will also go over some of the benefits of using this service and some of the potential use cases for it. AWS SNS is a cloud-based messaging service that allows you to send notifications and messages to subscribers. It is a fully managed service that can scale to support millions of subscribers. You can use it to send messages about changes in your AWS resources, such as when an Amazon EC2 instance is launched or terminated. You can also use SNS to transmit other types of messages, such as alerts, SMS, and text messages. In addition, you can use SNS to fan out messages to multiple services, such as Amazon SQS, Amazon Lambda, and HTTP/S endpoints.

What is AWS SNS?

AWS SNS is a fully managed push notification service that lets you send messages to all of your subscribers at once. With SNS, you can send messages to any number of recipients, including mobile devices and email addresses. SNS makes it easy to broadcast messages to large numbers of recipients, and provides you with the tools you need to manage your notifications.

The Different Types of AWS SNS

There are four different types of AWS SNS:

1. Standard queues

2. FIFO queues

3. Dead-letter queues

4. Topic-based subscriptions

Pros and Cons of AWS SNS

AWS SNS is a web-based service that allows you to manage and publish messages. The service is designed to allow users to create, manage, and delete topics, as well as subscribe and unsubscribe from these topics. AWS SNS is a simple notification service that can be used to send notifications to one or more recipients.

The main advantage of using AWS SNS is that it is very easy to set up and use. There is no need to install any software or configure any hardware. All you need is an account with Amazon Web Services (AWS). Setting up a topic and sending a message can be done in just a few minutes.

Another advantage of using AWS SNS is that it offers a variety of ways to send messages. You can send messages via email, SMS, or push notifications. You can also choose to have your messages delivered immediately or delayed until a certain time.

The main disadvantage of using AWS SNS is that it does not offer the same level of control as some other notification services. For example, you cannot specify which subscribers will receive which messages. This can be a problem if you need to ensure that certain messages are only sent to specific people.

Overall, AWS SNS is a simple and easy-to-use notification service that offers a variety of advantages over other similar services.

What are the benefits of using AWS SNS?

AWS SNS is a highly available, durable, secure, and fully managed pub/sub messaging service that enables you to decouple and scale microservices, distributed systems, and serverless applications.

SNS provides a low-cost infrastructure for large-scale publish/subscribe messaging with one million Concurrently Consuming Subscribers and Low Latency. With SNS you can fan out messages to large numbers of subscribers, including other AWS services such as SQS queues, Lambda functions, and HTTP endpoints.

SNS allows you to group multiple recipients using topics and also gives you the ability to send messages directly to individual recipients (endpoints). SNS is a pull-based delivery system which means that recipients have to actively poll the service to receive messages. This makes it a good fit for workloads where message latency is less important than throughput or when the receiving application is not always connected to the network.

How to get started with AWS SNS?

There are a few things you need in order to get started with AWS SNS:

1. An Amazon Web Services (AWS) account. If you don’t have one already, you can create one at

2. A device or application that can send messages to an AWS SNS topic. This could be a web server, email server, mobile app, etc.

3. A way to receive messages from an AWS SNS topic. This could be an email address, SMS number, mobile app, etc.

4. Optionally, you may also want to create an Amazon Simple Storage Service (S3) bucket to store archived messages, or an Amazon DynamoDB table to store information about your topics and subscriptions.

Once you have all of the above set up, you are ready to start using AWS SNS!

Alternatives to AWS SNS

There are a few alternatives to AWS SNS that provide similar functionality. These include Google Cloud Pub/Sub, Azure Event Grid, and Kafka. Each has its own benefits and drawbacks, so it’s important to choose the one that best fits your needs.

Google Cloud Pub/Sub is a managed pub/sub service that allows you to send and receive messages between applications and services. It’s highly scalable and offers features such as message filtering and topic management. However, it doesn’t support push notifications to mobile devices.

Azure Event Grid is a cloud-based event processing service that enables you to build event-driven architectures. It offers features such as routing, filtering, and delivery guarantees. However, it’s not as widely adopted as other options, so there may be less support available if you run into problems.

Kafka is an open-source stream processing platform that can be used for pub/sub messaging, among other things. It’s highly scalable and offers features such as partitioning and replication. However, it requires more setup and administration than some of the other options.


AWS SNS is a powerful tool that can help you keep your applications and systems running smoothly. By using SNS, you can send notifications to all of your subscribers quickly and easily. In addition, SNS can also help you track the delivery of your messages and ensure that they are delivered in a timely manner. With so many benefits, it’s no wonder that AWS SNS is becoming increasingly popular among developers and system administrators.
