Deploying a Production ready Django app on AWS

Deploying a Production ready Django app on AWS

In this tutorial, I will be going over to how to deploy a Django app from start to finish using AWS and EC2. Recently, my partner Tu and I launched our app Hygge Homes (a vacation home rental app for searching and booking vacation homes based off Airbnb) and we wanted to share with other developers some of the lessons we learned along the way.

Following this tutorial, you will have an application that has:

  • An AWS EC2 server configured to host your application
  • SSL-certification with Certbot
  • A custom domain name
  • Continuous deployment with Github Actions/SSM Agent
