Had the same thought. With AWS et al. it's just too easy to use the same instances and avoid that variable.

  On the contrary, with AWS et al, it's just too easy to have noisy neighbors :)

    I don't think many people are intentionally deploying their apps with replicas of different sizes, you're right. But this is it: noisy neighbours, inherent physical differences in even identical hardware, using different node sizes in your clusters. I think incidental differences in servers are very common, even within the same AWS instance category.

      I thought of another variant: with AWS autoscaling groups using spot instances you can list a number of different instance sizes and say "give me whatever is cheapest" and you'll often get a mix.
