SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It prevents brittle, environment-specific deployments by guiding you toward the Twelve-Factor methodology for cloud-native SaaS and microservices.

Core Features & Use Cases

  • Clear architecture rules for codebase, dependencies, and configuration so deploys are repeatable across environments.
  • Operational discipline around backing services, build/release/run separation, stateless processes, and port binding.
  • Production-ready observability & operations using stdout logs and disposable admin one-off processes.

Use it when planning a new service, refactoring an existing app for containers, or standardizing deployment practices across a team.

Quick Start

Ask: “Apply the twelve-factor methodology to my planned microservice design and point out the specific changes I should make to configuration, dependencies, backing services, process model, logging, and admin workflows.”

FAQPage Schema
What is the twelve-factor methodology for cloud-native apps?

The twelve-factor methodology provides architecture rules for cloud-native SaaS and microservices. It enforces statelessness, environment-based configuration, and build/release/run separation to prevent brittle deployments and configuration drift across environments.

How do I apply twelve-factor principles to an existing microservice?

To apply twelve-factor principles, evaluate your microservice against rules for codebase, dependencies, and configuration. You must refactor to use environment-based config, treat backing services as resources, and separate build, release, and run stages for repeatable deploys.

Why does my containerized deployment have configuration drift across environments?

Configuration drift occurs when environment-specific settings are baked into code rather than managed externally. Twelve-factor app design eliminates this by enforcing environment-based configuration and strict separation of build, release, and run stages.

Can I use twelve-factor design for refactoring an app for containers?

Yes, twelve-factor design is ideal for refactoring apps into containerized deployments. It standardizes operational discipline around stateless processes, port binding, and disposability to ensure reliable cloud-native microservice releases.

How do I handle logging and admin processes in stateless microservices?

Handle logging by treating logs as event streams written to stdout, avoiding local file storage. Execute admin one-off processes in environments identical to the main app to maintain operational consistency and disposability.

When should I not use the twelve-factor methodology for my application?

Avoid the twelve-factor methodology if your application requires persistent local state, relies on in-memory session storage, or cannot treat backing services as attached resources. It is strictly designed for stateless, cloud-native deployments.
