Agreed. EBS is really where the rubber meets the road in scaling web apps for EC2--esp. a de-normalized datastore.

- moe 17y agoAmen. Rackspace knows that very well, wonder why they didn't tell the author to use EBS for the comparison. Oh wait, I might have an idea... Anyways, as usual, don't trust any benchmark that you haven't faked yourself. This one, just like all other rackspace/ec2 comparisons that you see cropping up these days, was paid for by Rackspace and obviously tweaked to produce their desired outcome. Ironically they even point out the flaw in their setup by showing how the CPUs on the EC2 instances are not fully utilized. Guess what that means? It means the test was I/O bound. I'd be curious to see the test repeated, but this time with a RAID10 over a couple EBS volumes. Not sure Rackspace will pay for that one, though...
