The Pre-Flight Checklist: 9 Things to Analyze Before Cutting Any AWS Cost

On March 22nd, a developer published what amounts to a pre-flight checklist for AWS cost optimisation — not nine things to cut, but nine things to *examine* before you cut anything. The distinction is the entire argument, and it's one that gets lost constantly in the rush to show finance a lower bill. The post landed without a product pitch attached, no consulting firm watermark, no conference slot it was written to justify. That absence is either a signal of genuine practitioner wisdom or the reason it registered a score of 5.3 and attracted exactly one signal tracker. The checklist premise is the kind of thing that sounds self-evident until you've watched a team eliminate a Reserved Instance commitment and quietly kill the workload reliability it was propping up, or axe an underutilised Lambda only to discover it was the canary for something much larger. The cost line goes down; something else goes sideways three weeks later.

If confirmed as a reliable framework — meaning if engineers with production AWS environments at scale validate these nine checkpoints — the implications are straightforward and a little uncomfortable for the FinOps industry. The dominant narrative in cloud cost management is about tooling: connect your billing data, run the recommendations, approve the cuts. What this checklist argues, implicitly, is that the tooling skips a layer of analysis that only a human who understands the workload can perform. That's bad news for the dozens of cost optimisation platforms selling automated recommendations, and good news for the engineers who've been quietly explaining to management why the "easy wins" aren't actually easy. Second-order effect: if this kind of pre-flight thinking becomes standard practice, the timeline for AWS cost reduction projects lengthens — which changes how engineering teams scope and sell that work internally.

Watch for engineers in the AWS or FinOps communities either endorsing this checklist with their own war stories or publishing counter-frameworks — either response would tell you whether the nine-point structure holds up beyond one developer's experience.
