Isn't that true for most of AWS/EC2 ? A t2.2xlarge with 8 cores and 32 GB Ram costs $685 in 77 days. You can probably get an 8 core 32GB ram Intel/Amd machine for that price. Not a xeon, not "server-grade" but still the 77 days are not surprising to me. You pay a premium for the machine to be available on demand, being in a datacenter and being integrated in the AWS ecosystem.
