The Twelve-Factor App is a set of best practices for building modern, scalable software applications that run reliably in cloud environments. It emphasizes managing code with version control, storing configuration separately from code, handling dependencies explicitly, and treating backing services like databases as attached resources. It promotes stateless apps that can scale easily, continuous deployment, and logging that’s aggregated for analysis. These principles help developers create apps that are easy to update, reliable, and flexible across different environments, ensuring smooth operation and growth in today's dynamic, cloud-based world.
