I’ve been doing this for 30+ years and it seems like the push lately has been towards oversimplification on the user side, but at the cost of resources and hidden complexity on the backend.

As an Assembly Language programmer I’m used to programming with consideration towards resource consumption. Did using that extra register just cause a couple of extra PUSH and POP commands in the loop? What’s the overhead on that?

But now some people just throw in a JavaScript framework for a single feature and don’t even worry about how it works or the overhead as long as the frontend looks right.

The same is true with computing. We’re abstracting containers inside of VMs on top of base operating systems which is adding so much more resource utilization to the mix (what’s the carbon footprint on that?) with an extremely complex but hidden backend. Everything’s great until you have to figure out why you’re suddenly losing packets that pass through a virtualized router to linuxbridge or OVS to a Kubernetes pod inside a virtual machine. And if one of those processes fails along the way, BOOM! it’s all gone. But that’s OK; we’ll just tear it down and rebuild it.

I get it. I understand the draw, and I see the benefits. IaC is awesome, and the speed with which things can be done is amazing. My concern is that I’ve seen a lot of people using these things who don’t know what’s going on under the hood, so they often make assumptions or mistakes that lead to surprises later.

I’m not sure what the answer is other than to understand what you’re doing at every step of the way, and always try to choose the simplest route (but future-proofed).
