That's not entirely fair. The AWS t family aren't dedicated CPUs. They're burstable, there is a token system that decides if you get to use them to full capacity and for how long: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstable-performance-instances.html https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstabl...

Thanks. Do you know which EC2 instance would be most comparable to what Fly is offering with their dedicated-cpu instances?

  Anything not these: > The EC2 burstable instances consist of T4g, T3a and T3 instance types, and the previous generation T2 instance types. Your point still stands. Here's a m6g.2xlarge with 32GiB of memory and 8 vCPUs (AWS Graviton2 Processor / arm64): https://instances.vantage.sh/aws/ec2/m6g.2xlarge?min_vcpus=8&region=us-east-2&cost_duration=monthly&selected=m6g.2xlarge&os=linux&reserved_term=Standard.noUpfront https://instances.vantage.sh/aws/ec2/m6g.2xlarge?min_vcpus=8... Monthly cost: $224.84

    But then Gravitons are cheaper than x86. Though apparently the x86 variants are still only around $252.29/mo. Fly compares better on the low end of scale. AWS t3a.nano 512MB (2vcpu but 1h12min burst only, you can normally only consume 5% of that!) is $3.431/mo Fly shared-cpu-1x 512MB 1vcpu $3.19/mo

  Short answer: no. Long answer: When you consider ARM vs AMD vs Intel vs current-gen vs last-gen, AWS sells several 8-core 32-GB machines that have wildly varying performance characteristics. It used to be that the manner of virtualization impacted performance, too. I think that might be less the case now. To know if you're getting good value, you really need to try a few different vendors and benchmark then, either with real workloads or synthetic ones.

This is actually a benefit of AWS and other large public clouds. You have a choice due to their size. If AWS's investment in Gravitron design works well for your workload, it's a ~30% cost savings. They're able to invest in designing and producing the chips due to their size. A company like fly.to is limited in selection and heavy R&D.

      Sure, I personally like the Graviton instances. For workloads that care more about throughput than latency, they offer excellent performance-per-price. The OP was asking what was "most comparable" to Fly's offering. I assumed they meant "what would similar performance cost elsewhere". By switching from Intel to ARM, they're buying something fundamentally different. Maybe it's a better fit overall! But I didn't understand that to be what they were asking.

        I think we're on the same page. I only wanted to further contrast for readers the difference between something like fly.to and AWS. There's a lot of pros / cons, and one of them is selection. I wasn't sure what the dedicated instances for fly.io were running on (can't find it on this page: https://fly.io/docs/about/pricing/#plans https://fly.io/docs/about/pricing/#plans). To truly do an apples / apples compare there's networking capabilities, storage, and other considerations also.
