I think we're focused on the wrong thing when we look at what tech works for a company like Amazon or Facebook or Netflix.
We should be looking at what tech works when you *don't* have a small army of staff engineers optimizing it. I want to know what I can scale *without* paying someone a half million dollar salary to do it.
There should be more case studies on things that don't have a billion-dollar company propping them up, humming along quietly on a cheap-ass VPS somewhere.
