FAQPage Schema
What is the 12-factor app methodology for building cloud-native applications?

The 12-factor app methodology is a set of best practices for building scalable, maintainable cloud-native applications. It ensures software-as-a-service apps remain portable and resilient by enforcing rules for codebase management, dependency isolation, configuration, and stateless processes.

How do I design microservices for high scalability and portability?

To design scalable microservices, follow a methodology enforcing stateless processes, dependency isolation, and port binding. This approach guides backend services and APIs toward horizontal scalability and disposability, ensuring they are easy to deploy and maintain.

Can I use the 12-factor principles to refactor a monolithic application for containerization?

Yes, the 12-factor principles are ideal for refactoring a monolithic application for containerization. The methodology enforces build/release/run separation, backing services, and dev/prod parity to transition legacy software into portable cloud-native processes.

What is the best way to manage configuration and logging for backend API services?

The best way to manage configuration and logging for backend API services is isolating config in the environment and treating logs as event streams. This stateless approach ensures portability across execution environments and simplifies administrative processes.

When do I need to separate build, release, and run stages in a CI/CD pipeline?

You need to separate build, release, and run stages in a CI/CD pipeline to maintain strict dev/prod parity and disposability. This separation ensures cloud-native applications are portable, resilient, and easy to deploy across environments.

Why does my cloud-native application fail to scale horizontally?

Your cloud-native application may fail to scale horizontally if it violates stateless processes or stores local state instead of using backing services. Applying 12-factor principles ensures processes are stateless, disposable, and capable of horizontal concurrency.
