In this tutorial, you'll learn how to build and deploy a CRUD application (a "To-Do List" API) using Python, FastAPI and AWS. The application will be hosted serverlessly on the cloud, and will persist "to-do" (task) data for different users. We'll also write integration tests for our API using PyTest.
