But what is the real story?
While MS moving to Skylake before AWS is interesting, I wonder why AWS has chosen to wait?
As you mention, AWS are cloud pioneers and the big cloud providers have a reputation for getting early access to new hardware to play with before it's available to the rest of the market.
So are AWS being punished by Intel preventing the use of the new chips or is AWS just unimpressed with what Intel has to offer at present? Or did AWS use up their brownie points on the last chip launch and now have to wait patiently.
