I'm no expert but have gotten into this whole thing trying to get one set up for my university. One problem I've come to find is that no one seems to discuss about is the total network usage if you are hosting this on cloud. The egress on this seem bankruptable on any of the major cloud providers. How are people doing self hosting if they don't have an idle Intel xeon on prem? Where else can I get affordable egress pricing on ~35 TB/ month / 250 users?
