It is really easy to get yourself a provisioned IOPS volume; when creating the volume there’s a new selection.
One of the things that has long annoyed me about Amazon EC2 network and storage performance is that it is highly variable. The target for provisioned IOPS is exactly in the sweet spot of where I want it to be; database servers.
With provisioned IOPS, it appears that we’re seeing the first semblance of SLA’s or guaranteed quality of service for storage in the cloud. This is huge!
I’ve setup a multi-volume RAID set and am running performance tests and the numbers look good but what I like the most so far is that they are steady. That’s just awesome! More to come as I get the results.
