What is a 12 factor application
12-factor app is a methodology or set of principles for building the scalable and performant, independent, and most resilient enterprise applications. It establishes the general principles and guidelines for creating robust enterprise applications. 12-factor app principles got very popular as it aligns with Microservice principles.
What are the twelve factors ?
- Code base - One code base
- Dependencies - Declare and isolate the dependencies
- Config - Store config in an environment
- Backing Services - treat backing resources as attached resources
- Build/Release/Run - explicitly separate build and run
- Process - execute application as one or more stateless processes
- Port Binding - export services via port binding
- Concurrency - scale out via the process model
- Disposability - robustness through fast start and graceful shutdown
- Dev/Prod parity - keep. dev and prod as similar as possible
- logs - treat logs as event streams
- Admin - run admin/management tasks as one-off processes.
What is the Google Cloud Architecture Framework
