In cloud storage, which term describes the ability to automatically adjust resources to meet demand?

• A. Scalability
• B. Elasticity
• C. Open
• D. Flexible

Answer: (B)

Elasticity is the ability to automatically adjust resources to meet demand. In cloud storage, this means the system can ramp storage capacity or compute resources up when traffic or workload increases, and scale them back down as demand decreases, often in real time. This automatic resizing helps ensure performance while avoiding paying for idle resources, which is why elasticity best describes this behavior. Scalability, while related, refers to the overall capability to handle growing workloads and may not imply automatic, on-the-fly changes. Open and Flexible aren’t standard terms that capture this specific automatic provisioning aspect.
