Drupal 8 provides a new, unified system to manage configurations. In Drupal 8, all configurations are saved in configuration entities that match a defined configuration schema. This system provides a standard way of deploying the configuration between Drupal site environments and updating the site configuration.

Once the configuration is created, or imported, it goes into an immutable state. If a module tries to install the configuration that exists, it will throw an exception and be prevented. Outside the typical user interface, the configuration can only be modified through the configuration management system.

The configuration management system can be manipulated through a user interface provided by the Configuration management module or through the command-line interface tools. These tools allow you to follow the development paradigm of utilizing a production site and a development site, where changes are made to the development site and then pushed to production.
