You have given me a whole other perspective to an aws customer. I spend a lot on aws (70k/m +) but id be happy if i had core2duo cpus!
What sort of work do you have that requires the latest generation ? Or more why do you want the latest ?
Id expect aws to always be behind the ball - are they the right platform for you?
Gce is interesting, im moving half of my infra over there - but again its not really about their hardware offerings. Its more about being multi cloud/redundant
