A large e-commerce company is experiencing unpredictable traffic spikes during seasonal sales events. To handle these fluctuations efficiently without over-provisioning infrastructure, they require a cloud service model that automatically scales computing resources up or down based on demand. Which cloud characteristic directly supports this requirement?
- ABroad network access
- BOn-demand self-service
- CMeasured service
- DRapid elasticity
Show answer & explanationAnswer & explanation
Correct answer: D. Rapid elasticity
Rapid elasticity allows cloud resources to be scaled up or down quickly and automatically to meet fluctuating demand, which is essential for handling unpredictable traffic spikes efficiently.
Why the other options are wrong
- A. Broad network access relates to accessibility, not resource scaling.
- B. On-demand self-service relates to user provisioning, not automatic scaling.
- C. Measured service is about tracking resource usage for billing, not dynamic scaling.
Rapid Elasticity
The ability of cloud computing resources to be quickly and automatically scaled up or down to meet fluctuating demand.
- Handles unpredictable workloads.
- Optimizes resource utilization.
- Reduces costs by avoiding over-provisioning.
Memory trick: On-demand, Broad, Pooled, Elastic, Measured: Every cloud has these features.
