12 Factor App

Introduction In the modern era, software is commonly delivered as a service: called  web apps , or  software-as-a-service . The twelve-factor app is a methodology for building software-as-a-service apps that: Use  declarative  formats for setup automation, to minimize time and cost for new developers joining the project; Have a  clean contract  with the underlying operating system, offering  maximum portability  between execution environments; Are suitable for  deployment  on modern  cloud platforms , obviating the need for servers and systems administration; Minimize divergence  between development and production, enabling  continuous deployment  for maximum agility; And can  scale up  without significant changes to tooling, architecture, or development practices. The twelve-factor methodology can be applied to apps written in any programming language, and which use any combination of backing services (database, queue, memory cache, etc). I.
