What you’re describing is “good enough service levels for what I need” not “the same level of service as AWS” (or a superior level, as the parent comment implied). If some sanely architected code was all you needed, then you’d expect at least other cloud/IaaS providers to be able to match AWS service levels. Which they can’t, and which some little software shop most certainly cannot either.
