Measured service is the cloud computing technology that meters resource usage and ensures consumers only use what is allotted. Managing Cloud guidance explains that cloud systems automatically measure usage of resources such as storage, processing power, and bandwidth.

This metering supports transparency, cost control, and pay-as-you-go billing models. Consumers are charged based on actual consumption, which encourages efficient resource usage and prevents over-allocation.

Business impact analysis evaluates operational risk, subscription-based services define billing models, and resource pooling refers to shared infrastructure. Therefore, measured service is the correct answer.
