Where is the application route map usually set?

The application routing map (routing) is usually defined in the code responsible for navigation and handling URLs or internal transitions. In web applications, this could be a route configuration file (for example, routes.rb in Ruby on Rails or app-routing.module.ts in Angular).

In mobile applications, such as iOS, routes are set in controller code or through storyboards, where transitions between screens are defined.

In the DevOps context, when it comes to traffic routing, the routing map is set in configuration files of load balancers, proxy servers, or network equipment settings.
