Which feature of the AWS Cloud gives users the ability to pay based on current needs rather than forecasted needs?

Explanations:

AWS Budgets helps users set custom budgets to monitor their costs but does not directly influence pricing based on current needs.

Pay-as-you-go pricing allows users to pay only for the resources they use, making it flexible and responsive to current needs rather than forecasts.

Volume discounts provide lower prices based on the quantity of resources purchased but do not adjust costs based on immediate usage needs.

Savings Plans offer a way to save on AWS costs by committing to a certain usage level over a period, which does not align with the pay-as-you-go model.
