Artifactory vs Git for Infrastructure Version Control / Configuration Management
This is a simple thumb rule one could follow 


Use version control (git, svn, cvs) for the work product created by humans
Use artifact management tool (artifactory, nexus, apache archiva) for the software bundle (artifacts) created by the system thru build or packaging process
