Show answer & explanation

Correct answer: D

  • I. Scalability: This allows users to increase or decrease resource capacity (like storage or processing power) instantly based on demand. In cloud environments, this is often handled through Auto-scaling, ensuring you only use what you need.

  • II. Self-service (On-demand Self-service): Users can provision computing capabilities, such as server time and network storage, automatically as needed without requiring human interaction with the service provider.

  • III. Pay-per-use (Measured Service): Similar to a utility like electricity, cloud computing follows a consumption-based model. we are billed only for the specific resources and duration we actually use, which shifts costs from Capital Expenditure (CapEx) to Operational Expenditure (OpEx).
