White Paper – Implementing the Twelve-Factor App Methodology 

Application development has gone through a fundamental shift in the recent past. Developers are under pressure to deliver software that runs in a variety of environments including enterprise data centers and cloud platforms. The modern software is expected to scale with no major changes to the code. Software has to be shipped rapidly to deliver new features and user experiences.

In the era of web, mobile, and device computing, application development needs to adopt a new methodology. The rise of cloud, containers, and microservices has led to a new paradigm of developing and deploying software. The twelve-factor app methodology advocates a set of patterns and practices for designing contemporary applications that take advantage of cloud infrastructure. Since these applications are born in the cloud to exploit the capabilities of modern infrastructure, they are often referred as cloud-native applications.

This report introduces the twelve-factor app methodology to developers focused on building contemporary, cloud-native applications.
