Twelve-Factor App

The Twelve-Factor App methodology provides architectural guidelines for building portable, resilient software-as-a-service applications optimized for modern cloud platforms and container runtimes.

When to Use

• Cloud-Native Application Architecture: Designing stateless, scalable web applications intended for Kubernetes, PaaS, or container clusters.
• Legacy Replatforming: Modernizing monolithic legacy software into containerized, cloud-ready deployment units.
• Zero-Downtime Rolling Deploys: Ensuring services can boot fast, survive sudden terminations, and run alongside differing versions.
• Standardizing Microservice Conventions: Establishing uniform configuration, logging, and dependency isolation standards across teams.
