This module provides a centralized tool for storing all of the configurations that your applications need in order to work. Within the Java world, it's quite common to have .properties and .yml files that store all of the required configurations.

Spring offers the ability to create different profiles, in order to deal with different environments, using files with the previously mentioned extensions. However, it also has the option to keep all of the configuration centralized in a server, where you can store values and even encrypted information. When clients need to access this secret information, the configuration server has the ability to decrypt the information and make it available to the client. Furthermore, you can change the configuration values on the fly. The files storing this configuration reside inside of a Git repository, which gives us the additional benefit of accounting for the changes applied in the configurations.
