Talend Administration Center is provided together with Nexus artifact repository and an archive of Talend scripts to initialize the Artifactory repository. It is used to store software updates, ESB and Data Integration Job artifacts.
This tool is used for the Software Update feature and its instance holds the talend-updates repository where the updates are retrieved by the user.
It can also be used as a catalog for the Jobs, Services, Routes, and Generic OSGi Features created from Talend Studio or any other Java IDE. For this, two repositories are available: repo-snapshot for development purposes and repo-release for production purposes.
