I talked to an engineer in that industry. The tools are pretty similar, all build into docker images in this case. He specifically works on the entertainment systems (similar to what you experience in long-haul flight). The most surprising insight was that they still ship harddrives around. Well, that might be related to the size of the movie files here. Remote debugging (European waters) is tricky but works. Rarely do they have to send somebody on-site or rather on-ship, but it happens. He didn't deal with hardware (server racks, internal networking) that was a different team.

Your surprise is interesting to me, because I would have predicted it, and would have found the reverse surprising.
To me, hard drives in this context make sense. Slow, unreliable scaled, very expensive Internet, abundant space and power for the hard drives, demand for entertainment media (as distinct from news and sports) all lead to "cache content locally".
I expect limited real-time media (sports) can then be added using the limited external bandwidth available.
