The buzzwords are ultimately meaningless but that sounds more specific to ”infrastructure as code” than the meaning of “devops”. With iaac basically being one of the facets of devops. Does that sound right to you?
I don't know. IAAC is a much newer term than DevOps, and used primarily in combination with IAAS, so I think its meaning can't be used as an argument to give or take away meaning to the term DevOps.
