Except by that very statement, you slam the door in the face of tons of existing
knowledge within organizations. This slope has a sheer face.
Promoting a single solution would do as much harm as it would good, for all it’s
worth. In such a scenario, the most advocated method would become the only
understood method, in spite of all other deployment efforts. Each project that
did not have the most mindshare would become more irrelevant than they are now
and further slip into decay. For those that did not have the fortune or
foresight to land on this hypothetical winning side, what for their efforts,
evolve or gtfo?
I'm not saying Fuel or Salt or Chef or Puppet or Ansible needs to be the
'winner', because there isn't a competition, at least in my opinion. The way I
see it, we're all working to get to the same place. Our downstream consumers
don’t really care how that happens in the grand scheme, only that it does.
