Cloud Scale Apps, Cloud Scale Testing

While at Interop I participated in a Tech Field Day event where Spirent was talking about their new Axon product as well as the possibility of usage of Blitz.io. It was an interesting discussion but gave me some food for thought. As we move to cloud scale apps based on platforms such as Pivotal (EMC World was just down the street), OpenShift, and others, we need a way to test those applications at scale. Spirent and Ixia provide these tools, but would they be used in this new model.
