Oracle cloud sucks ass but also has a good free tier for their arm instances, you get 24gb memory and 4 cores (and can split those resources across separate VMs or just one big VM)

also note that once you pick a datacenter region you're stuck with that region forever.
I was about to use this but it needs a credit card or a debit card without pin.
also, I believe they have free AMD instances too, but it's much less generous.
