> SSH-only server administration: Vim’s sub-second startup and tiny memory footprint make it the default choice for editing config files on remote boxes, containers, and minimal Linux images where every extra process matters. It’s also nearly guaranteed to already be installed, since most base Linux and macOS images ship Vim or vi by default, unlike Emacs, which almost always requires a separate install step.
That's one way to do it. A better way to accomplish this with emacs is to use tramp mode which uses ssh as a tunnel to edit remote files in a local emacs instance. It just needs ssh access and doesn't require emacs to be installed remotely.
