Network Performance: d2.xlarge - Moderate, d2.2xlarge - High, d2.4xlarge - High. This ambiguity alone is the reason I and probably others will look elsewhere.

  If you put it like that every EC2 performance metric is ambiguous when not using dedicated instances.

    They tell you specifically how much RAM you get, and there is no confusion. They also tell you exactly how much storage you get. In this case they very specifically tell you disk read throughput. So there are a lot of metrics that are not ambiguous. Imagine if they told you that you get a "moderate" amount of RAM, and maybe it could be 4.5GB, or maybe it's 9GB. There would be benefits if Amazon gave SLA style promises for these sorts of instances. When they see that they are falling short, they redistribute loads or add hardware to meet the promise. Otherwise it's generally somewhat meaningless because if you can't plan on it, you can't build a plan around it.

  Because a) you actually want dedicated services in the first place and would not consider EC2 regardless, or b) you like being lied to?

all at a very affordable price AWS really needs to get back in touch with reality. $500 USD/mo for a server with 32G Ram and 3x2T disks is not 'affordable', it's a rip-off. For that money you can rent 10 machines of that size at Hetzner/OVH - and they will be dedicated hardware.

  That's the on demand pricing. You should check the math on reserved pricing and consider the TCO. Not saying you're wrong but it's at least important to accurately compare.

    Reserved pricing requires a year lock in. I can get something like that for about 40 Euros [and guaranteed 100mb/s on 1 gbit port] with no setup fee and no lock in beyond 30 days. Even with reserved pricing for 3 years its $5,715 = 5715/36 = ~$158/month + Bandwidth. The TCO with Amazon is only cheap when you have a very, very high variability in load. [e.g. Netflix]

      Can you link to this deal for an instance with similar specs as the D2.xlarge for 40 a month? that sounds like a great deal and I don't need to host in the US, but this instance type is what I've been looking for.
