A cloud provider offers a service where customers can deploy their custom code without managing the underlying servers or operating systems. The customer is only billed for the actual compute time consumed by their code executions. Which cloud computing concept does this billing model align with?
- AResource pooling
- BMeasured service
- CRapid elasticity
- DBroad network access
Show answer & explanationAnswer & explanation
Correct answer: B. Measured service
Measured service is a key characteristic of cloud computing where resource usage is monitored, controlled, and reported, allowing for transparent billing based on actual consumption, precisely as described in the scenario.
Why the other options are wrong
- A. Resource pooling describes the sharing of resources among multiple consumers.
- C. Rapid elasticity is the ability to scale resources up and down quickly.
- D. Broad network access refers to accessibility over standard network mechanisms.
Measured Service
A characteristic of cloud computing where resource usage is monitored, controlled, and reported, providing transparency for both the provider and consumer.
- Enables 'pay-as-you-go' or 'pay-per-use' billing models.
- Allows consumers to track and optimize their resource consumption.
- Often includes metrics like compute time, data transfer, and storage used.
Memory trick: Measured Service: The cloud is 'metered' like your utility bill.
