Twelve-Factor Method

The Twelve-Factor Method is a set of best practices for building reliable, scalable software applications, especially in cloud environments. It emphasizes keeping code and data separate, managing dependencies clearly, and automating deployment processes. This approach encourages stateless apps that rely on external resources, making updates and scaling easier. By following these principles—like configuring environment variables, treating logs as data streams, and designing for portability—the method helps developers create flexible and maintainable software that can grow and adapt efficiently in modern cloud-based systems.
