Okay, so I understand then that the values that are shown on the "EBS optimized by default" table, on the columns "Maximum throughput" and "Maximum IOPS", are then the maximum IOPS and throughput for those instances. And they are unable to go beyond that level. The "Dedicated EBS Bandwidth" is the only bandwidth EBS-optimized instances can get. And is **impossible** for them to get any shared network bandwidth for EBS (like non-optimized EBS instances). Is that correct?
