My 2 cents on this - I have used the Oracle Cloud free tier trying to get the VMs running. The default resource usage seems higher than what you would get on Hetzner/ionos/digital ocean and the resource monitors are a good chunk of that usage. Configuration was also considerably more difficult for someone with little experience such as myself... Achieving the same task (setting up a BookStackApp server) took considerably longer than it did on most services on which you pay.
What I'm trying to say is that you do get what you pay for (or don't).
