Zorluk: ZorCloud Characteristics and Features (Elasticity, On-Demand, Resource Pooling)

A software company operates an automated image-processing web application. During burst processing windows triggered by unexpected customer batch uploads, the hosting platform automatically provisions additional virtual processing nodes within seconds to maintain response times. As soon as the processing backlog clears, the surplus compute resources are automatically deallocated without any administrative interaction. Which NIST cloud characteristic is best demonstrated by this automated behavior?

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

Cevap

Rapid elasticity
Rapid elasticity enables cloud infrastructure resources to be dynamically provisioned and decommissioned, often automatically, to scale seamlessly in response to real-time workload fluctuations. In this scenario, the immediate automatic addition of nodes during workload bursts and their subsequent deallocation when idle demonstrates rapid elasticity.

Adım Adım Çözüm

1
Analyze the operational scenario features
Identified automatic provisioning during sudden traffic surges and immediate automatic deallocation when demand drops.
The key workload pattern involves real-time expansion and contraction driven by workload demands.
2
Evaluate against NIST cloud characteristics definitions
Rapid elasticity allows capabilities to be elastically provisioned and released, in some cases automatically, to scale rapidly outward and inward commensurate with demand.
Automatic expansion and contraction to match real-time workload without human action defines elasticity.
3
Differentiate from alternative cloud characteristics
Selected Rapid elasticity over On-demand self-service (user-initiated provisioning), Resource pooling (multi-tenant shared hardware), and Measured service (metered usage tracking).
The automated scaling mechanism specifically distinguishes rapid elasticity from static provisioning or administrative self-service.
