AWS Cloud Practitioner CLF-C02 Practice Question

The principle of economies of scale refers to the cost advantage that arises with increased output. In cloud computing, as resource utilization increases, the overall cost per unit of resource typically decreases, allowing for more cost-effective scaling. By leveraging the cloud provider's economies of scale, the retailer can scale its resources while benefiting from lower prices as usage grows. The other options do not directly target cost optimization through scaling: global reach focuses on geographic distribution, purchasing excess on-demand capacity increases rather than reduces cost, and diversification across services is not chiefly a cost-saving measure.
