Too Long; Didn't Read
This tutorial takes a look at triggering AWS Lambda functions from AWS SNS messages. All the code from this tutorial is already on GitHub if you want to check out the end result right away. The code itself will just mimic the behavior of a random complex computation. This mimics a heavy computational background task such as data processing, image manipulation or machine learning calculations. It’s a huge anti-pattern for asynchronous workflows, which is our case. Using the Dead Letter Queue as a pool of error logs is a smart use-case.
