One thing that stands out from both types of stacks that I've worked with, is that most of the time, doing things simply the first time without putting in a lot of work to guess what other complications will arise later tends to produce a stack with a higher uptime even if the code gets messy later.

There are certainly some things to plan ahead for, but if you start with something complex it will never get simple again. If you start with something simple, it will get more complex as time goes by but there is a chance that the scaling problems you anticipated present in a little different way and there's a simple fix.

I like to say, 'Simple Scales' in design reviews and aim to only add complexity when absolutely necessary.
