In the early days of programming, developers often hardcoded values directly into their scripts. If an application needed to connect to a database, the database URL and password were explicitly typed into the source code. This approach creates significant bottlenecks:
For example, consider a web application. The code defines how to connect to a database, but the configuration file specifies which database to connect to, using parameters like: Database host addresses Port numbers Secret login credentials Maximum connection limits config
These manage the functional settings of a specific program. Examples include setting the default language, defining the number of items per page in a UI, or enabling a newly released beta feature via a feature flag. Infrastructure Configs In the early days of programming, developers often

Let’s put theory into practice. Imagine a Go microservice that needs to read config from a file, then override it with environment variables.
