04/21/2025, 7:12 PMYou just need to think about where you're hosting it on. Do you have 3 hypervisor nodes? What are the other single points of failures in your own infra? Switches? Routers? ISPs?

04/21/2025, 7:16 PMOk but if i dont have haproxy theb if one node goes down the others wont be able to get up right? Not sure if im clear this is for a dev env to start so I can test diff scenarios
