Hot take: Here is one of the bad things of "the industry"'s obsession with scale. It makes doing a thing once and fast become trivialized. If it's at scale then it's always on. Like 10 of them are always on. And that leads to trivializing efficiency and startup time. It also leads to trivializing the runtime complexity of the OS / system. So that is creepily the programmer for one, giving up an aspect of the art of programming (optimization and efficiency). And two, it is training the programmer to play into the hand of $BIG_SERVER_RENTIER. Our "best practices" as in IT industry happen to be good at consolidating resources in a way that rich people can get richer.
