Talend Administration Center uses Nexus or Artifactory to store software updates, ESB, and Data Integration Job artifacts. This tool is named Talend Artifact Repository.
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.
So when unzipping Talend Administration Center zip file, you will find two archive files. One is called Artifact-Repository-Nexus-VA.B.C.D.E containing scripts to configure Nexus. The other is called Artifact-Repository-Artifactory containing Talend scripts to initialize the Artifactory repository.
Nexus is based on Sonatype Nexus. You need to install Nexus and to configure it with the initialization file in Artifact-Repository-Nexus-VA.B.C.D.E or to configure it manually. For more information on how to use it, see Sonatype Nexus documentation on http://www.sonatype.org/nexus.
