The scenario I am particularly interested is multiple servers having daemons that run on certain configuration parameters. (since, this is a learning exercise. i welcome any thought beyond this particular case)
The question is, where should the configuration parameters sit.
A. a central database table
B. a config file pushed to each of the boxes
These are the most common I’ve come across. The notable others being, in code constants (needs recompile to deploy. so bad option unless they really are constants), config file mounted on a shared location.
Just wanted to know from the community on how you go about making the choice.
It all depends on the scale of the operation you’re managing.
If the number of locations is large and/or changes are frequent, use a database.
Otherwise, use configuration files.
If access to a centralized database is too slow or unacceptably a point of failure, but the scale is still large, use an automated system like Puppet.
