The glossary defines the core concepts and terminology of Backbone Issue Sync.

Centralized configuration

In the centralized configuration model, the synchronized Jira instances connect using the HTTPS protocol.

The synchronization is administered and run from a single Jira instance. Backbone must still be installed on the other JIRA instance, but this is only for licensing purposes. 

note: this term is outdated, and not used in Backbone version 4.2 or higher.
