AWS S3 File Upload + Lambda Trigger (Tutorial In Python) | Step by Step Guide

S3 is an easy to use all purpose data store. Frequently we use it to dump large amounts of data for later analysis. Using S3 Put events with Lambda, we can shift this process to an event driven architecture. In this video, I show you how to set up a S3 Put Event Trigger that invokes a lambda function every time a file is added to your s3 bucket. This allows for event driven processing and other neat applications!
