I think the AWS failures on iops tests should've been examined more prior to publication, or at least explained more to the reader.

AWS General Purpose EBS volumes scale based on volume size, so a purely naively-done test with a default AMI's performance could be as low as 24 iops (8GB*3 IOPS per GB) once exhausting it's burst iops quota. I think it's unfair to compare apples to oranges here, as you can make these volumes scale to absurd numbers, if you have the cash.

Agree need to use 1TB EBS volume (the smallest volume that removes bursting limits) and an EBS optimized and enhanced networking instance to be accurate. I'll be the first to admit that AWS has a serious problem with overcomplicating things though. You really shouldn't have all these different options and gotchas.

The point of this test wasn't to determine the absolute limits. It was to determine what the actual real-world performance would be on the instances/servers we would actually be using.
