So I've worked with AWS and with our internal clusters as a dev. My experience has been that I have to make work-arounds for both, but at least with AWS, I don't have to spell out commands explicitly to the junior PEs.
EDIT: I should be clear, our PEs are generally pretty good, but because their product isn't seen by upper management as the thing which makes money, they're perpetually understaffed.
