I have checked out saltstack (not in too much detail, since I have been busy with puppet). But I wasn't sure if there was an equivalent to exported resources in saltstack (I want to use them for automated monitoring and orchestrating of other services), since that is a pretty useful thing and I was somewhat skeptical about having everything defined in YAML, since there are somethings that I think one wouldn't be able to do... but I have been meaning to look into it!
