Amazon DynamoDB offers low, predictable latencies at any scale. A number of outages at the height of the 2004 holiday shopping season can be traced back to scaling commercial technologies beyond their boundaries. Dynamo might have been the best technology in the world at the time but it was still software you had to run yourself.
