Which cloud computing benefit does AWS demonstrate with its ability to offer lower variable costs as a result of high purchase volumes?

Explanations:

Pay-as-you-go pricing allows users to pay only for the resources they consume, but it does not specifically address the lower variable costs derived from high purchase volumes.

High availability refers to a system’s ability to remain operational and accessible over time, which is unrelated to the cost benefits associated with high purchase volumes.

Global reach indicates AWS’s ability to provide services across various geographical locations, but this does not explain the cost benefits resulting from economies of scale.

Economies of scale occur when the cost per unit decreases as production increases. AWS can leverage its large-scale operations to negotiate better prices and pass those savings on to customers, demonstrating lower variable costs.
