A company's cloud provider issues an invoice each month based on the exact number of compute hours consumed and the exact amount of storage used. Which cloud computing characteristic is being applied?
- AMeasured service
- BBroad network access
- CElasticity
- DResource pooling
Show answer & explanationAnswer & explanation
Correct answer: A. Measured service
Measured service (also called metered service) means cloud usage is automatically monitored and controlled, and customers are billed based on actual consumption, similar to a utility.
Why the other options are wrong
- B. Broad network access refers to availability over the internet from various devices.
- C. Elasticity describes the ability to scale resources, not billing based on usage.
- D. Resource pooling describes shared infrastructure serving multiple customers.
