Difficulty: EasyCloud Characteristics and Features (Elasticity, On-Demand, Resource Pooling)

An IT administrator is configuring cloud services for a company that experiences sudden spikes in web traffic during promotional events. The administrator wants the system to automatically provision additional compute resources as traffic increases and deprovision them when demand drops, without manual human intervention. Which of the following cloud characteristics best describes this capabilities?

  1. Rapid elasticityAnswer
  2. B
    On-demand self-service
  3. C
    Resource pooling
  4. D
    Measured service

Answer

Rapid elasticity best describes the automatic scaling up and down of resources based on demand.
Rapid elasticity allows cloud resources to automatically scale up to handle sudden traffic increases and scale down when traffic normalizes, eliminating the need for manual administrative intervention.

Step-by-Step Solution

1
Analyze the requirements described in the scenario.
The requirement emphasizes automatic provisioning during traffic spikes and automatic deprovisioning when traffic decreases without manual intervention.
Identifying key requirement phrases such as dynamic, automated expansion and contraction isolates the target cloud feature.
2
Evaluate cloud characteristics against the requirements.
Rapid elasticity specifically provides automated horizontal or vertical scaling to match fluctuating application demands seamlessly.
Comparing definitions confirms rapid elasticity is the only feature focused on dynamic auto-scaling capabilities.
