This is really great for people who build out datacenters, but a large portion of consumers of compute+data will lease that from providers like Amazon and Azure, which means they cannot enjoy the benefit of the Disk I/o ~= local network i/o equation. There's no guarantee that a parcel of EC2 nodes is in a single rack, or even in a single datacenter, and so network i/o is not comparable to disk i/o.
Am I mistaken?

- wmf 11y agoAccording to the docs, EBS goes up to 500 MB/s while a d2.8xlarge can read 3,500 MB/s from local disk so local is still faster (if you can actually use that much throughput).
