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

A financial enterprise deploys internal infrastructure where physical processor cores, system RAM, and SAN storage devices across multiple server racks are combined into a single operational framework. This framework dynamically allocates and reallocates virtualized hardware capacity to separate corporate departments based on real-time computational demands while concealing physical host locations. Which cloud computing characteristic is primarily demonstrated in this scenario?

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

Answer

Resource pooling
Resource pooling allows cloud providers to aggregate physical storage, processing, and memory resources into a shared pool. These physical assets are dynamically assigned and reassigned to virtual workloads across multiple internal departments or external tenants without revealing physical hardware locations.

Step-by-Step Solution

1
Analyze the operational requirements described in the scenario.
Physical infrastructure (CPU, RAM, storage) is aggregated across hardware racks and dynamically allocated to isolated virtual instances based on department workload demand.
Identifying how physical hardware is shared among multiple workloads allows proper categorization of the NIST cloud characteristic.
2
Map the technical operational model to cloud architectural characteristics.
Combining physical hardware resources to serve multiple workloads with dynamic allocation and physical location independence defines Resource Pooling.
Resource pooling abstracts physical hardware details from the client while maximizing hardware utilization across multiple tenants.
