An enterprise healthcare organization is auditing its cloud infrastructure operations. Match each operational workload requirement on the left with the essential NIST cloud computing characteristic it primarily exemplifies on the right.
- An image processing service automatically spins up worker virtual machines during peak diagnostic hours and releases them when processing queue length drops to zero.Rapid Elasticity
- A clinical trial group provisions new database instances for data analysis at any time using a self-service management portal without submitting service desk tickets.On-Demand Self-Service
- Isolated virtual networks for separate hospital departments run dynamically allocated RAM and processor cores from shared physical blade servers.Resource Pooling
- An IT telemetry system logs the exact gigabytes of outbound traffic and storage capacity used per department to generate itemized monthly chargeback reports.Measured Service
Cevap
The image processing service matches Rapid Elasticity; the clinical trial group provisioning matches On-Demand Self-Service; the department virtual networks on shared physical hardware match Resource Pooling; and the telemetry logging for itemized monthly chargeback reports matches Measured Service.
Rapid Elasticity is demonstrated by automated scaling up and down based on processing queue depth. On-Demand Self-Service is demonstrated by users provisioning cloud infrastructure directly through a portal without administrative intervention. Resource Pooling is demonstrated by serving multiple isolated departmental environments from shared physical server hardware. Measured Service is demonstrated by monitoring resource consumption to generate usage-based billing reports.
