🗳️ POLL: Have you heard of or used "The Twelve-Factor App" methodology? YES/ NO/ WHAT IT IS?

· devops

🔑 The Twelve-Factor App is a methodology designed to build cloud-native applications by standardizing development practices. It provides a shared language, but its understanding can vary. This book clarifies the 12 factors and expands on them to address modern app development challenges.

🚀 Heroku, a pioneer in the public cloud, introduced these factors to guide developers in building cloud-ready apps that scale and deploy quickly.

 

The 12 factors:

1️⃣ Codebase: One codebase tracked in revision control, many deploys

2️⃣ Dependencies: Explicitly declare and isolate dependencies

3️⃣ Configuration: Store configuration in the environment

4️⃣ Backing Services: Treat backing services as attached resources

5️⃣ Build, release, run: Strictly separate build and run stages

6️⃣ Processes: Execute the app as one or more stateless processes

7️⃣ Port binding: Export services via port binding

8️⃣ Concurrency: Scale out via the process model

9️⃣ Disposability: Maximize robustness with fast startup and graceful shutdown

🔟 Dev/prod parity: Keep development, staging, and production as similar as possible

1️⃣1️⃣ Logs: Treat logs as event streams

1️⃣2️⃣ Admin processes: Run admin/management tasks as one-off processes

 

📈 While still relevant, the tech landscape has evolved. The book introduces new guidelines beyond the original 12, covering API-first, telemetry, security, and more. It emphasizes modern best practices for cloud-native applications, ensuring scalability, rapid deployment, and adaptability.

 

📚 This methodology fosters a virtuous cycle where mastering one factor eases the adoption of others, leading to more robust, scalable cloud apps.
