Java EE 8 Design Patterns and Best Practices

When to use the external configuration store pattern

The use of the external configuration store pattern is recommended when sharing configuration files with applications or when updates are required without the redeployment of an application. Sharing configuration files allows us to easily manage the configurations of an application, as all applications will see and be impacted by the update, which is done in one location. Using this pattern will also minimize the risk of error when updating the configuration file, so the use of this pattern is a good practice to adopt.
