When finance teams see cloud costs for the first time, they always ask the same question: "Why are we paying 30% more than the company next door for the same servers?" The answer is usually not that the workload is inefficient, but that the company next door bought commitments. AWS's On-Demand pricing is a premium for "freedom to turn on/off anytime without promises," and if you give up some of that freedom, AWS discounts up to 72%. Without understanding the essence of this trade, you can never solve SAP-C02 cost scenarios.
