H3: First half of the 12-factor app

“Let’s go invent tomorrow instead of worrying about what happened yesterday.” — Steve Jobs

Introduction

Many businesses wish to avoid relying solely on third-party technologies, and it may be helpful to examine the ideas that underpin an application design. It will also assist you in evaluating and comparing various solutions for resolving the underlying difficulties. Heroku, as a platform on which hundreds of millions of apps are deployed, has had to isolate the basic design principles for cloud-based applications and provide an environment that makes them simple to create and manage. The 12-Factor App is a manifesto that describes these ideas.

The first part of this post walks through the first six factors and reworks a simple Arduino IoT application with them in mind. Part 2 continues with the remaining six factors, demonstrating how this design allows easier integration with containerization technologies like Docker. I won’t cover advanced container orchestration, but I would recommend you give it a shot

1. Codebase

Yup, 💯 GitHub.

Our codebase is located on GitHub. If you are a software developer, chances are that you have interacted with GitHub. I personally love Github but also have an appreciation for Gitlab. Initially, I was using Gitlab for…
