Build AWS Serverless Web Applications With Python

For years, web development has continued to evolve alongside programming languages, tooling, and frameworks. It started out with static web sites before moving on to dynamic sites that were rendered on the server. Over time, as JavaScript frameworks gained functionality and popularity, there was a shift towards putting more of the logic into the front end, and using the back-end as a supporting API.

Throughout all the changes in web development over the years, the server has been a constant. Regardless of the languages, tools, and frameworks used, there’s always a server running the code. And that’s something that hasn’t changed. What has changed is that cloud providers now make it easy for software engineers to focus on writing their code, without having to focus on the underlying server.

In this lesson, you'll build a serverless web application using Python 3.6. You'll use Lambda, API Gateway, S3, DynamoDB, and Cognito to create a multi-user to-do list application based on Vue.js.

Note: The Apple M1 chip isn't compatible with this lesson currently. We recommend using a different device.
