My computer science teacher (also the vice-headmaster) set up moodle for our school and a few others. I have no idea how other schools managed their online classes. Jitsi was hosted by a few teachers who voluntarily managed all this infrastructure for schools in my state (Germany, BW). They didn't have enough servers since there wasn't much demand until the pandemic. These scaling problems meant only teachers could use their cam (which most students were quite happy about).
