Question 1 of 15

According to the 12-factor app methodology, how should configuration (e.g. database URLs, API keys) be stored?
Hardcoded directly into the application's source code for simplicity
Configuration should be identical and unchangeable across every environment
In a config file that is always committed to the same repository as the code
In environment variables, strictly separated from the code, so the same build can be deployed across different environments (dev/staging/prod) with different config
