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

A data analytics firm hosts its infrastructure in a cloud provider's facility. The provider maintains a large, multi-tenant infrastructure where physical compute cores, system memory, and storage drives from vast server racks are dynamically allocated and reallocated among multiple corporate clients according to real-time workload demands. Individual clients are unaware of the exact physical locations of the underlying hardware components supporting their workloads. Which cloud computing characteristic is described 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 is the cloud characteristic where the provider's computing resources are pooled to serve multiple consumers using a multi-tenant model, with different physical and virtual resources dynamically assigned and reassigned according to consumer demand, while masking specific physical location details from the customer.

Step-by-Step Solution

1
Analyze the key attributes presented in the scenario.
The scenario describes a multi-tenant model where physical compute, memory, and storage are dynamically allocated across multiple clients from a unified hardware base, location-independently.
Identifying the defining features of cloud infrastructure characteristics is necessary to classify the operational model.
2
Map the attributes to official cloud characteristics.
The concept of serving multiple customers using a shared pool of physical and virtual hardware resources without tenant knowledge of exact physical locations represents resource pooling.
NIST definitions specify resource pooling as multi-tenant allocation of location-independent physical and virtual assets.
