CompTIA Cloud Essentials+ (CLO-002)Business Principles of Cloud EnvironmentsEasy
A company is comparing cloud providers. Provider A offers a licensing model where they charge per virtual CPU hour and per gigabyte of RAM consumed. Provider B offers a model where they charge a flat monthly fee for a pre-defined package of resources, regardless of actual usage within that package. Which type of licensing model does Provider A primarily represent?
- AConsumption-based licensing
- BPer-device licensing
- CSubscription licensing
- DPer-user licensing
Show answer & explanationAnswer & explanation
Correct answer: A. Consumption-based licensing
Provider A's model, charging per virtual CPU hour and per gigabyte of RAM consumed, is a classic example of consumption-based licensing. This model bills customers based on their actual usage of resources, which is a hallmark of cloud computing's pay-as-you-go nature.
Why the other options are wrong
- B. Per-device licensing charges based on the number of devices accessing the service.
- C. Subscription licensing typically involves a fixed recurring fee for access to a service or set of resources.
- D. Per-user licensing charges based on the number of individual users.
Consumption-based Licensing
A licensing model where software or service costs are directly tied to the actual usage of resources, such as CPU hours, data transfer, storage, or API calls, embodying the 'pay-as-you-go' principle of cloud computing.
- Pay-as-you-go model
- Charges based on actual resource usage
- Common in cloud computing for IaaS and PaaS
- Costs fluctuate with demand
