Speaking of containers I've always wondered if running a GUI app (something like a kiosk) would work in these sorts of containers? I know you can do it hackily in docker by playing with X and xfvb. But does any of them natively (easily) support it?
Sometimes I wonder about the strength of this sort of sales behaviour but ultimately I guess they make their own ecosystem by requiring specialized techies to translate even the sales pitch - promoting a sort of "it has got to be super-hyper-vigilantly efficient if I can't even understand what its good for, plus I can wash my hands of it professionally if it fails because anyone in their right mind can see the necessity of having someone else evaluate the usefulness of a system this incomprehensible"-response from certain managers.
I would expect native graphics (including 3d graphics) are a feature we'll see down the road.
