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.
