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

A company is migrating an internal application to a cloud environment. The IT department requires the ability to provision virtual machines immediately without human interaction from the cloud vendor. Additionally, the cloud infrastructure must dynamically share physical compute resources across multiple customer organizations. Which of the following cloud characteristics directly fulfill these operational requirements? (Select TWO.)

  1. On-demand self-serviceAnswer
  2. Resource poolingAnswer
  3. C
    Type 1 hypervisor isolation
  4. D
    Software as a Service delivery

Answer

On-demand self-service and Resource pooling
On-demand self-service grants users automated provisioning capabilities without vendor staff involvement. Resource pooling allows cloud providers to combine physical computing infrastructure to serve multiple tenants efficiently.

Step-by-Step Solution

1
Evaluate the requirement for provisioning resources immediately without vendor intervention.
Identify 'On-demand self-service' as the matching characteristic.
On-demand self-service enables consumers to unilaterally request and configure cloud computing capabilities as needed automatically.
2
Evaluate the requirement for sharing underlying physical hardware across multiple customers dynamically.
Identify 'Resource pooling' as the matching characteristic.
Resource pooling combines physical computing assets to serve multiple tenants based on demand.
