Certified Cloud Security Professional (CCSP)Cloud Concepts, Architecture and DesignMedium
A cloud service provider (CSP) offers a service where customers can deploy their custom code without managing underlying servers, operating systems, or even the runtime environment. The customers are billed based on the number of requests and the execution time of their code. Which cloud computing concept is best illustrated by this billing model?
- AMeasured Service
- BResource Pooling
- CRapid Elasticity
- DOn-demand Self-service
Show answer & explanationAnswer & explanation
Correct answer: A. Measured Service
Measured service is the cloud characteristic where resource usage is monitored, controlled, and reported, allowing for transparent billing based on actual consumption, such as requests and execution time.
Why the other options are wrong
- B. Resource pooling is about sharing infrastructure, not the billing model for usage.
- C. Rapid elasticity is about automatic scaling, not the billing based on usage.
- D. On-demand self-service is about provisioning resources without human intervention, not the billing aspect.
Measured Service
A cloud computing characteristic where resource usage is monitored, controlled, and reported, providing transparency for both the provider and consumer.
- Enables pay-per-use billing models
- Provides visibility into consumption
- Supports optimization of resource usage
