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

A university library system plans to host its public book search catalog and student reservation web portal on Microsoft Azure to handle peak traffic during registration weeks. However, due to regional data sovereignty regulations, all student borrowing histories and personally identifiable information (PII) must remain on physical servers located within the university's on-campus data center. Which cloud model is represented by this implementation?

  1. Hybrid cloudAnswer
  2. B
    Public cloud
  3. C
    Platform as a Service (PaaS)
  4. D
    Capital Expenditure (CapEx)

Answer

Hybrid cloud
The correct answer is hybrid cloud because the deployment combines public cloud resources (Microsoft Azure) for the public-facing catalog and reservation portal with private, on-premises infrastructure (the university's local physical servers) for storing sensitive student data to meet regulatory compliance requirements.

Step-by-Step Solution

1
Analyze the deployment components of the university library system.
The system uses two distinct environments: Microsoft Azure (a public cloud provider) for the catalog and portal, and an on-campus data center (on-premises/private infrastructure) for storing sensitive student records.
Identifying the hosting environments is necessary to determine the overall cloud model.
2
Determine the cloud model that describes the combination of public cloud and private/on-premises infrastructure.
A hybrid cloud model is defined by the integration of public cloud services with private on-premises infrastructure, allowing data and applications to be shared between them.
This matches the scenario where public web hosting is combined with local database hosting for compliance.
