icecream (icecc) is basically this. It’s “cloud” in that it’s distributed, but it requires surprisingly high bandwidth to the cluster, so it basically requires an office LAN connection. Or for your editor to be on that connection a la VSCode’s remote thing.
This is probably the other big reason why "cloud compilers" are rare. Not much point in using one if you can compile the source locally more quickly than you can upload it.
