Interesting, nice article! Is it possible to send any type of notifications? For example, a notification every time someone replies to your tweet?

I know the example is pointless, but just trying to understand how one can use it. 😊

[AWS SNS](https://aws.amazon.com/sns/?whats-new-cards.sort-by=item.additionalFields.postDateTime&whats-new-cards.sort-order=desc) can send messages to many kinds of subscribers: HTTP webhooks, Email, SMS, SQS, Push notification.

In order to trigger it, you can use Lambda like this article shows, or [EventBridge](https://aws.amazon.com/eventbridge/). The possibilities are endless.

[Catalin Pit](https://hashnode.com/@Catalinpit) thank you for reading!

My use case for this is to be used doing live sporting events. I write software to score different types of [sports in realtime](https://auprosports.com/). I use AWS Lambda and AWS CloudWatch Event Rules to periodically (CRON) query our database to find potential errors. If there are errors our team is notified immediately. Some of our team members get emails while others prefer SMS.

I have an article on deck to query an RDS database using AWS Lambda. Stay tuned!

Great article [Phillip Ninan](https://hashnode.com/@phillip_ninan)

I just wanted to bring something to your attention. With the `aws-sdk`, you can either use the `callback` function (on the request method) - OR - use `.promise()` with `.then()` or `await`. It seems you have made a mix of moth here. The `.promise()` method does not take a callback.

Did I miss something?

[Benoît Bouré](https://hashnode.com/@bboure) No, you are correct! I forgot to add a `.then()`. I updated the article and the Github source code. Ironically, the code still executed properly with this error, but the logs were never printed.

Thank you for pointing that out!!
