You can't really compare an ARM AWS vCPU to a bare-metal Ryzen 9 core though. And the AWS offer is missing storage and bandwidth, which are extremely expensive if you want something comparable.

  That's why I choose the `d` EC2. They come with NVMe SSD ephemeral storage and in terms of bandwidth, AWS will beat it anyway. R6 is around 10Gbps if I remember correctly.

    With 8TB of not throttled IO ?

      How are you going to throttle local storage on bare-metal exactly? Ephemeral isn't over network, it's directly attached. So yes, even 8TB.
      - speedgoose 6y ago
        Yes the local storage is not throttled on bare-metal. Maybe these new AWS instance with ephemeral storage are not throttled as well, I can't find the information. Anyway, it's not 8TB but 1TB and on the AWS price calculator it costs 650€ for this instance. You may have access to special prices.

    Hetzner gives you 20TB/month outgoing bw + 1euro/TB if you add 39 euro for 10gbps uplink - or un-metered 1gbps bw. Even if you have "up to 10 gbps" bw from aws - it's going to be much more expensive! And if you just need low latency (and "no" data), 1 gbps would probably serve you just as well? So at those prices (essentially no bandwidth) - you could get two physical servers from hetzner... Fwiw i agree comparing aws to dedicated doesn't make much sense - but unless flexibility is important - I don't see aws comming out on top from such a simple comparison.

The thing is though for many workloads (I'd even say most) applications get I/O constrained way quicker than CPU, so scaling CPU will not give you the boost that you expect on AWS and the other big cloud providers. Keep in mind that PCIe4 NVMes can do 5-7GB/sec (gigabytes - not gigabits) read and write, with up to 500K IOPS. Compare that to RDS on AWS which charges a comical $0.10 per IOPS-month, so just for IO it would be $50k/month (and for many DBs IOPS are more important than CPU) to meet the performance of one NVMe SSD, which can be bought retail for probably $200. I don't think I've ever seen such ridiculous pricing. I do understand AWS can be more expensive, but it is just outrageous margin for IO performance (and external bandwidth, but that's a whole other story!).
