One of the most popular services on AWS is Lambda, which lets you run code in response to some event, without having to worry about the underlying servers.
In this video, I’ll provide a short overview of Lambda, its benefits, and why you would use it. Then in a hands-on tutorial, I’ll walk through how to create a Lambda function (in Python 3.9) that’s triggered by a file upload to an S3 bucket. Finally, I’ll show you how to delete the S3 bucket and the Lambda function.
If you want to follow along, you can find the Python code here for the Lambda function: https://docs.google.com/document/d/1R9jO94MEjTy1ffb-TL4HOP1a_3ZIkwEU5lzLyEUGj5k/edit?usp=sharing
