As with everything in software engineering, any average dev can fire up a few containers with Docker, but running anything in a real environment takes a whole team of people who actually understand the platforms involved in order to deliver a fully functional service, hopefully via properly designed code (TF) for ease of reusability. Most devs simply don't care to think about that part, and then throw it over the fence for "someone else" to deal with. Just as long as they can say "DONE!" (I created a thing!), that's all that matters.
