 Modern software is almost always 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 of a new developer joining the project;
-* Have a clean contract with the underlying operating system, offering maximum portability between runtime 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).
