The only thing I dislike about that EC2 guide is that it’s suggesting to use EBS instead of the regular EC2 instance storage
This is an apt question in the light of the prolongued Amazon outage, Reddit’s experience with EBS, the unpredictable EBS performance, and Netflix’s Adrian Cockcroft explanation of multi-tenancy impact on the Amazon EBS performance. Maybe someone could answer it.
