Question 11

A start-up is evaluating cloud providers for its new application. The company's CTO learns that the cloud provider negotiates bulk discounts with hardware vendors and data center operators, and passes these savings on to customers through lower service prices. The CTO also notes that the provider's vast infrastructure allows customers to benefit from the provider's operational expertise in running large-scale data centers. Which benefit of cloud computing does this scenario BEST represent?

Accepted Answer

Economies of scale. Economies of scale occur when a cloud provider achieves lower per-unit costs by operating at a massive scale. The provider purchases hardware in bulk, optimizes data center operations, and leverages expertise across many customers. These savings are then reflected in lower prices for all customers. The scenario directly describes this benefit—lower prices from bulk purchasing and operational expertise passed on to the customer.
