CompTIA Cloud Essentials+ (CLO-002)Cloud ConceptsEasy
A cloud architect is designing a new application that needs to handle sudden, unpredictable spikes in user traffic without manual intervention. The application must automatically provision and de-provision resources based on demand. Which cloud characteristic is most relevant to this requirement?
- ARapid Elasticity
- BResource Pooling
- CBroad Network Access
- DMeasured Service
Show answer & explanationAnswer & explanation
Correct answer: A. Rapid Elasticity
Rapid elasticity is the ability of a cloud system to quickly scale resources up or down in response to changing demand, often automatically. This perfectly matches the requirement for handling sudden, unpredictable traffic spikes without manual intervention.
Why the other options are wrong
- B. Resource pooling refers to the provider's ability to serve multiple consumers with pooled resources, not the automatic scaling for a single application.
- C. Broad network access means resources are accessible over the network, which is a general cloud characteristic but not specific to automatic scaling for demand spikes.
- D. Measured service refers to the ability to monitor and bill for resource usage, not the automatic scaling of resources.
Rapid Elasticity
The ability of cloud resources to be quickly and elastically provisioned or released to scale rapidly outward and inward commensurate with demand.
- Automatic scaling of resources.
- Handles unpredictable demand spikes.
- Minimizes over-provisioning and under-provisioning.
Memory trick: BROAD METERS RAPIDLY POOL SELF-SERVICE.
