AWS SNS to Lambda Tutorial in Python | Step by Step

SNS and Lambda integration is a crucial component of building event driven applications. In this video, I show you how to hook up a Lambda function to an SNS topic with the sns message content as the input payload. I start out by talking about the general concepts of SNS and Lambda before heading into the console and creating the resources. From there, I show you how to add the necessary permissions and how to test your setup.

thank you for the video, I found it very helpful. For the info, permissions section when you create sns topic also used to give permissions to other aws services (such as s3 ) to publish messages on SNS topic.

Correction: 6:50, encryption in transit is enabled by default for almost all AWS services. The encryption offered here is server side encryption-- encryption at rest. Often this feature is deemed as worthless and overlooked; however it's extremely to enable and forget about. It's definitely worth the extra layer of security.

I've done this before, but it wasn't working when using IAC (Terraform). I walked along through the tutorial and was missing the Lambda trigger (14:53) which TF calls a "lambda_permission." Thanks!
