I think this is backwards training, personally. I think azs as separate
failure domains were done like that for a reason by amazon, and make good
sense. What we've done is overload that with cells, aggregates etc which
should have a better interface and are a different concept. Redefining well
understood terms because they don't suite your current implementation is a
slippery slope, and overloading terms that already have a meaning in the
industry in just annoying.
