Oracle Cloud's prices are the same across all regions, which is nice. They do not offer any reserved discounts, but do offer a 50% discount for preemptible (spot) instances. One complication is that their prices are per "Oracle CPU" (OCPU). This seemed to make sense originally, as it corresponded to physical cores - the A1 instances had 1 OCPU per core, so 1 OCPU = 1 vCPU, while SMT x86 had 1 OCPU = 2 vCPU (threads). But then, possibly thinking that their users are getting comfortable with it, they threw a wrench by making 1 OCPU for newer (still non-SMT) ARM types A2 and A4 be equal to 2 vCPU / 2 full Cores. I can't think of a reason for this other than to confuse their customers.
