-
A. CostCLOUD = Σ(UnitCostCLOUD / (Revenue – CostCLOUD))
-
B. CostCLOUD = Σ(UnitCostCLOUD / Revenue)
-
C. None of these
-
D. CostCLOUD = Σ(UnitCostCLOUD × (Revenue + CostCLOUD))
Explanation
CostCLOUD = Σ(UnitCostCLOUD / (Revenue – CostCLOUD)).
- This formula reflects the relationship between unit cost, revenue, and total cost in a cloud computing deployment.
- The cost is adjusted by factoring in both the unit cost and the difference between revenue and total cost.
-
