i think there's a clash of definition in that thread. Devops originaly was a job title for sysadmins with high automation skills and able to deploy to a cloud.
it later evolved to something much more management related.
Depends who you ask. Everyone seems to invent the definition that local-optimize for themselves. The book Good To Great goes into the dynamics, outside of IT, so is a general pattern.
