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

An international logistics organization is migrating its customer-facing booking application to Microsoft Azure to handle seasonal spikes in traffic. However, due to strict national regulations, the database containing historical customer shipping records must remain on physical servers located in the company's local corporate headquarters. The on-premises database will be connected to the Azure web application using a secure network connection.

Which cloud model and expense type combination represents this deployment?

  1. A hybrid cloud model where the Azure web application represents operational expenditure (OpEx) and the on-premises database represents capital expenditure (CapEx).Answer
  2. B
    A public cloud model where all components are shifted to a consumption-based operational expenditure (OpEx) model because the Azure web application is connected to the database.
  3. C
    A private cloud model where all infrastructure costs are classified as capital expenditure (CapEx) because the database controls the application data flow.
  4. D
    A Software as a Service (SaaS) model where both the database and the web application are managed entirely by Microsoft as an operational expenditure (OpEx).

Answer

A hybrid cloud model where the Azure web application represents operational expenditure (OpEx) and the on-premises database represents capital expenditure (CapEx).
The deployment combines public cloud services (Microsoft Azure) with private infrastructure (on-premises database servers), which defines a hybrid cloud model. Furthermore, Azure services use a consumption-based pricing model, which falls under operational expenditure (OpEx), while the owned and managed on-premises physical hardware represents capital expenditure (CapEx).

Step-by-Step Solution

1
Analyze the hosting environment of the different components to determine the cloud deployment model.
The web application runs on Azure (a public cloud) while the database remains on physical servers at corporate headquarters (a private infrastructure). The combination of public and private environments constitutes a hybrid cloud model.
Classifying where the resources reside is the first step in identifying the correct cloud model.
2
Analyze the financial characteristics of each hosting environment to determine the expense type.
The public cloud resources on Azure are consumption-based, representing Operational Expenditure (OpEx). The on-premises database servers require physical hardware ownership and maintenance, representing Capital Expenditure (CapEx).
Distinguishing between OpEx and CapEx helps determine the financial impact of the cloud migration strategy.

Key Concept

Identifying hybrid cloud models and distinguishing between CapEx and OpEx.
