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.
