Definitely a go to services for sending out notifications for AWS users.

The SNS is great at integration . The services is almost able to interact with all the other AWS services and able to get the notifications for them and deliver the same to the users. The Notifications are delivered to user with minimal delay .

At times there are cases were few notifications are lost when the s3 trigger event was set up to throw the notification when the file arrives.

I used SNS together with SQS to broadcast messages to several recipients.

Simple friendly API, very easy to use when you are already using the infrastructure from Amazon. Not expensive, pay as you go model. Based on pushing messages, not polling. Integrates great with Amazon SQS.

It has hard limits on the number and size of messages per second. It is difficult to decide whether to use SNS and SQS or, for example, EventBridge.

Pricing is great considering the amount of functionalities it provide. Provides nearly realtime delivery which is very important for critical time sensitive applications

Does not store messages hence it is always needed to back it up with other tools ( For example SQS). This increases the complexity of application and increases the cost

* AWS integration with other services like SQS or lambda, which help you a lot to speed up your development. * Out of the box http calls and email deliveries. I have used it extensively and the most valued feature for me is the fanout messages, i.e sending the same message to multiple consumers(sqs queues) so changes in the system can be propagated to the workload.

The biggest con I have with SNS is that there is no way to store the sent messages, making it costly and hard to implement when something goes wrong and you need to resend all the previous messages. Probably it's because its not the purpose of the tool but usually I have hit this issue when choosing SNS as an event source.

the best feature I most like about SNS is its on-time alert notification and if there is one message already there. Then the SNS queue will start and works on the First in first-out perspective.Even we can integrate mail as well as SMS for notification

for the free tier, the account is free for one million requests but after that, the pricing is hiked like a rocket. They need to work on it because many of our clients stop using it because of price issues.

It is a very simple service as the name says but makes the solution more reliable which lets you send/track alerts and notifications, which can be integrated with other AWS services too making it more robust and useful.

This lets you programatically send messages/notifications to all your desired customers with the help of triggers as messages or emails which is easily scalable and can be managed without any worries too. In our usecase, we used it for push notifications to via emails mainly to the audience we intent to send. Configuration and setting up takes a couple of minutes.

Not too much customization provided because it is mainly managed by AWS. Service Documentation can be improved with more in-detail information, including integrations with other services just for reference.

We use AWS SNS in many projects to sending push notifications, mail and SMS. We can setup a Multi Factor Authentication system integrated in a SSO flow really fast thanks to Lambda functions triggered on SNS events.

AWS SNS results really simple to integrate in our systems and on external services. API documentation is as usual for AWS serices really complete and easy to understand.

For SMS notifications AWS SNS can be more expensive compared to other services but it remains a cheap and cost effective tool.

Easy to configure and implement integration with backend. As every AWS service, has 100% uptime. Best in class in my opinion.

there is no problem I encountered throughout my use of the service.

Simple management and monitoring: Amazon SNS provides a simple way to manage and monitor topic subscriptions and cost-effective: Amazon SNS offers a pay-as-you-go pricing model, allowing you to pay only for what you use.

It is expensive on high volume messages hanleing

I'm impressed with its reliability and ease of use. Setting up notification topics and subscriptions is straightforward, and the service's web interface makes it simple to view and manage the status of my messages.

Nothing much. The interface can be improved to make it more user friendly
