Recommended repository format for staging software binaries in nexus oss3


I’m planning to use nexus as a repository to stage software binaries like tomcat, jboss, etc. As there are multiple data centres in the environment, it would be preferred to host the main repository and upload artifacts in primary data centre, with proxy repositories in others so that the artifacts are automatically copied from primary data centre when needed.

Can you please suggest the recommended repository format for this use case?
