Don't just look at the execution you are building for, but also the team that will be maintaining it. That is, there are several values for "who" that you are building for. Each will have cause for you to reach to more complicated seeming solutions, as you go.
This is good advice. You should be aware of who you are building for. Designing your system to run on 100 containers orchestrated by Kubernetes is overkill for your average SaaS MVP, while counting on shell scripts is a recipe for disaster at FAANG scale. Scale matters.
