Most application, services, app, program, whatever has some kind of configurations. Some of the them are visible to the user, some of them are only available to the provider, some of them might be derived from other settings.

In larger applications, like web services and stuffs, configurations play a huge role. No one wants to recompile the whole program when there are needs to move the log file location, for example. Well-implemented applications provides numbers of configuration, so they are flexible enough to handle different environments and usages.

Below is what I think it should be taken in consideration when designing configuration management.

Configuration implementation is 'details'.

There are multiple way to keep and to read the configuration. It could be an in-memory objects, SQLite, SQL server, No-SQL server, Redis, or even a configuration server. Regardless, this should be considered as a 'detail'. The application should not aware of how these operations work. It should be able to query t
