There are two sizes of companies: those that can afford '1+ dedicated ____-person' and those that can't. Which should filter through to technology choices more than it does.
It's not 1+ person when a system needs to operate 24/7. To have a proper on-call rotation you need 5 to 8 people.
Often you start as the latter and grow toward the former.
That transition can be super super painful as you don't quite have enough work for the dedicated person.
Or, you can do like one of my former bosses, and just rattle off a list of 60+ major projects which would require a team of 10 to make any reasonable progress on in the near future, then pin it on one underqualified person, refuse to provide a proper budget, and continually press them about why targeted deadlines are being missed.
