Difficulty: MediumCloud Models (Public, Private, Hybrid, Multi-cloud)

A company plans to deploy a new application and wants to ensure that they have no responsibility for purchasing, maintaining, or upgrading the physical hardware. They also want to pay only for the resources they use on a consumption-based model, without any upfront capital expenditure. Which cloud model should the company choose?

  1. Public cloudAnswer
  2. B
    Private cloud
  3. C
    Hybrid cloud
  4. D
    Software as a Service (SaaS)

Answer

Public cloud
The public cloud model is correct because the cloud provider is responsible for purchasing, managing, and maintaining all physical infrastructure. Customers do not pay upfront capital expenditures (CapEx) and instead use an operational expenditure (OpEx) consumption-based model where they only pay for the resources they use.

Step-by-Step Solution

1
Identify the organization's infrastructure ownership requirement.
The organization wants to eliminate all responsibility for purchasing, maintaining, or upgrading physical hardware.
This requirement rules out any deployment models that involve on-premises or dedicated customer-owned physical hardware.
2
Identify the organization's financial model requirement.
The organization wants to avoid upfront capital expenditure (CapEx) and pay only for resources consumed (OpEx).
This requirement points to a shared-resource public cloud environment where billing is consumption-based.
3
Evaluate the matching cloud deployment model.
The public cloud model fits both requirements because the cloud provider owns the hardware and offers consumption-based pricing.
Neither private cloud nor hybrid cloud can satisfy the complete elimination of physical hardware ownership and upfront CapEx.

Key Concept

Cloud deployment models define the ownership of the underlying physical hardware and the financial structure of resources.
