Which benefit of the AWS Cloud helps companies achieve lower usage costs because of the aggregate usage of all AWS users?

Explanations:

While not needing to guess capacity is a benefit of AWS, it does not directly relate to lower usage costs through aggregate usage.

The ability to go global quickly is an advantage of AWS but does not specifically pertain to cost reduction through economies of scale.

Economies of scale refer to the cost advantages companies experience due to the large-scale operations of AWS, which leads to lower usage costs for all users.

Increased speed and agility enhance operational efficiency but do not specifically contribute to lower usage costs due to aggregate user usage.
