However, it is not a complete testing system, I have never seen them talk about testing non-software components, and I hope they do that as well. As we saw in the previous Amazon outage, part of the problem was a circuit breaker configuration.
When the hardware is outsourced how would you propose testing the non-software components? They do simulate availability zone issues (and AZ is as close as you get to controlling which internal power/network/etc grid you're attached to).
I suppose they could introduce artificial network latency/loss @ each instance - and could add testing around what happens when amazon's API disappears (as was the case friday).
Beyond that....the rest of it is up to the hardware provider (Amazon, in this case).
