What is Twelve-Factor App Methodology In Web App Development? What is the Twelve-Factor App Methodology? The Twelve-Factor App methodology, created by Adam Wiggins (co-founder of Heroku), is a set of best practices for building, distributing, and deploying the application in the cloud platform. It is called the twelve-factor app methodology because it has 12 diverse guidelines that help developers to build a simple yet scalable web app or SaaS application. These principles are the outcome of every experience and observation gained through the deployment of several Software-as-a-Service applications over the cloud. But why should you follow it, you may ask. Not following these guidelines may lead you to suffer from the same mistakes that other senior developers had while wasting your time in solving systematic issues. However, using this methodology, you might be able to take advantage of the tried experience that saves your time in the long-term.
