well, i dont have any comparison chart, i can work on one based on
requirements i've provided in initial letter, but:
i like ansible, but it is agentless, and it wont fit well in our current
model of communication between nailgun and orchestrator
cloudify - java based application, even if it is pluggable with other
language bindings - we will benefit from application in python
salt is been around for 3-4 years, and simply compare github graphs, it one
of the most used and active projects in python community
