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

Match each enterprise IT cloud scenario with the essential NIST cloud characteristic it primarily demonstrates.

  • An automated monitoring service dynamically provisions additional virtual compute nodes during unpredictable traffic spikes and instantly deallocates them when workload decreases.Rapid Elasticity
  • A developer provisions new containerized environments through an automated web portal within minutes without requiring human intervention from cloud provider staff.On-Demand Self-Service
  • A cloud provider serves multiple enterprise clients from shared physical server chassis and SAN storage arrays using multi-tenant software abstraction.Resource Pooling
  • A corporation monitors client virtual machine runtime, bandwidth consumption, and storage allocation to dynamically generate precise hourly billing statements.Measured Service

Cevap

Automated scaling based on real-time load matches Rapid Elasticity; self-provisioning via web portal without provider intervention matches On-Demand Self-Service; shared physical infrastructure serving multi-tenant clients matches Resource Pooling; tracking runtime and bandwidth for hourly billing matches Measured Service.
Each scenario maps precisely to its NIST essential cloud characteristic based on operational function: automated demand-based scaling aligns with Rapid Elasticity, self-service provisioning without provider assistance aligns with On-Demand Self-Service, multi-tenant hardware abstraction aligns with Resource Pooling, and usage-based metering aligns with Measured Service.

Adım Adım Çözüm

1
Analyze Scenario 1 (automated dynamic scaling and deallocation)
Identified as Rapid Elasticity because resources expand and contract automatically according to workload demand.
Rapid Elasticity focuses on seamless, real-time scaling without service interruption.
2
Analyze Scenario 2 (direct user provisioning via portal without provider staff)
Identified as On-Demand Self-Service.
On-Demand Self-Service allows users to acquire computing capabilities as needed automatically.
3
Analyze Scenario 3 (multi-tenant allocation over shared hardware)
Identified as Resource Pooling.
Resource Pooling leverages multi-tenancy where physical and virtual resources are dynamically assigned based on consumer demand.
4
Analyze Scenario 4 (granular metric monitoring for cost reporting/billing)
Identified as Measured Service.
Measured Service provides metering systems to monitor, control, and report resource usage transparently.
