In my experience, a higher portion of Azure customers are larger enterprise customers that engage professional services from Microsoft to architect things, etc. AWS is far more popular in general, but especially with smaller teams that are more self-directed, start with prototypes and iterate from there. It wouldn't surprise my if the latter often only built in redundancy after learning lessons the hard way, even though AWS provides the ability to do so from the get go. Purely conjecture, but that skew in the customer type is definitely there.
