Question

According to the Twelve-Factor App methodology, where should an application&#x27;s configuration data be stored to ensure portability across different deployment environments?

Accepted Answer

According to the Twelve-Factor App methodology, configuration data should be stored in environment variables. Environment variables are values defined outside of the application code that the operating system provides to a process at runtime. This approach ensures strict separation between config and code, which is essential for portability because the same application code can be deployed to different environments, such as development, staging, or production, without requiring any changes to the source code itself. Developers should never store configuration in constant variables within the code, as this would require a recompile or a code change every time the environment changes. By using environment variables, the application remains agnostic of its deployment environment, allowing it to adapt simply by reading different values from the system where it is running.
