I would guess that the ram requirement is because that presumes memcached, postgresql, and redis are all running co-resident with Zulip; if your setup can split those apart (because you have them sized independently, or because your "cloud" offers hosted versions of them) then I'd guess the Zulip container itself will likely get away with a lot less ram As always, my suspicion is that you'll get better help jumping into chat.zulip.org and describing your concerns
