AWS Cost Allocation and FinOps Architecture Deep Dive
I have managed AWS spend across organizations ranging from $50,000 to $8 million per month. The single biggest difference between organizations that control their cloud costs and those that hemorrhage money is not tooling or dashboards. It is architecture. Specifically, whether cost allocation was designed into the platform from day one or bolted on after the CFO started asking uncomfortable questions. This article covers the architecture I build for every engagement: tagging strategies that survive real-world entropy, CUR analysis pipelines that produce actionable data, anomaly detection that catches problems before they become invoices, and commitment optimization that maximizes discount capture without over-committing.
