Fair, but NASA facilities would be one of the organizations I would personally expect there to be an exception. They have all sorts of facilities where on-premise servers and capacity will be a lot better than some remote cloud offering.
I don't expect a lot of crossover between web dev and space exploration.
(As an ex-JPLer,) you would be very surprised how many internal tools this decade have been web-stack. Flight systems are one thing, but you need plenty of ground systems to support the effective use of assets in flight, and there's no reason to avoid one of the biggest UI platforms out there.
That makes a lot of sense! Thanks for pointing that out.
