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

A software development firm requires developer virtual machines that engineers can provision independently using a cloud management portal whenever new code repositories are created, without waiting for manual IT administration approval. Which cloud computing characteristic best describes this capability?

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

Answer

On-demand self-service
On-demand self-service allows consumers to provision cloud resources unilaterally without requiring direct intervention from cloud administrators or IT support personnel.

Step-by-Step Solution

1
Analyze the operational requirement presented in the scenario.
Engineers need the ability to directly request and launch virtual machines through an automated portal without waiting for administrative approval.
Identifying key operational workflows helps determine which specific NIST cloud characteristic is being leveraged.
2
Evaluate standard cloud characteristics against the independent provisioning workflow.
On-demand self-service directly enables users to acquire compute resources independently as needed without human-to-human interaction.
This matches the definition of on-demand self-service under cloud computing standards.
