> And generally if you have to scale you have money and money can make any system work That's the thing, this is not always true. It's true that generally you can throw money and hardware at a problem, but at some point you just reach the fundamental limit of the technology, at which point throwing money at the problem doesn't work. In fact, being in a position where you can throw money at the problem is _brilliant_, as spending money is easy. So the point of _scalable_ technologies is to enable you to scale just by throwing money at the problem. Case in point, at my old company we had this _massive_ Pg database running in RDS. It did not scale. Performance was terrible, and made the user experience shit. We were basically using the biggest instance size we could, with a few replicas powering read only endpoints. So at some point we migrated parts of it to Dynamo, and poof all of our problems went away, including operational ones.
