Twelve Factor App Methodology

The Twelve-Factor App methodology is a set of best practices for building and deploying cloud-native applications. It was developed by Heroku, a cloud platform as a service (PaaS) provider, and has since been widely adopted by organizations as a guide for building cloud-native applications.

The Twelve-Factor App methodology consists of 12 principles that are designed to help developers build applications that are easy to scale, maintain, and deploy in a cloud environment.

The term Cloud isn’t a physical entity but is meant to represent the infrastructure of the internet. It’s called Cloud to signify that the users of the Cloud don’t have to worry about the underlying complexities of the infrastructure but can use it as building blocks for their application. Behind the scenes, the cloud is a vast network of physical machines across the globe connected together and abstracted for its end users for dedicated tasks from running applications to storing data to managed applications.
