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

An organization is evaluating its infrastructure deployment options across different business units. Match each scenario to the cloud model that best describes its deployment structure.

  • A municipal police department hosting sensitive evidence management systems on dedicated servers owned and operated solely for their department within city hallPrivate cloud
  • A public university hosting its student enrollment portal entirely on Microsoft Azure to handle seasonal registration spikes without purchasing physical hardwarePublic cloud
  • A media streaming company that uses an on-premises datacenter for high-speed content editing and Microsoft Azure for distributing video to global usersHybrid cloud
  • A mobile gaming studio that deploys its new game servers across both Google Cloud Platform and Microsoft Azure to avoid vendor lock-inMulti-cloud

Answer

The scenario involving dedicated, locally owned infrastructure matches 'Private cloud'; the scenario using only Microsoft Azure matches 'Public cloud'; the scenario combining on-premises datacenters with Microsoft Azure matches 'Hybrid cloud'; and the scenario using both Google Cloud Platform and Microsoft Azure matches 'Multi-cloud'.
The correct matches map each business scenario to its respective cloud deployment model: the municipal police department using local dedicated infrastructure is a private cloud; the university using Azure alone is a public cloud; the media streaming company combining on-premises and Azure is a hybrid cloud; and the gaming studio using both GCP and Azure is a multi-cloud deployment.

Step-by-Step Solution

1
Identify the scenario involving dedicated infrastructure owned and managed by a single organization locally.
The municipal police department matches the definition of a Private cloud model because the hardware is owned and operated solely for them.
Private clouds are restricted to a single organization and can be hosted locally on-premises.
2
Identify the scenario where services are hosted entirely by a third-party cloud provider without the consumer owning the physical hardware.
The public university scenario matches the Public cloud model because the services are hosted on Azure and scale dynamically.
Public cloud features shared resource pools managed by third-party providers over the public internet.
3
Identify the scenario that combines local on-premises infrastructure with public cloud services.
The media streaming company matches the Hybrid cloud model because it integrates local editing setups with public Azure distribution.
Hybrid cloud models combine private infrastructure (like on-premises datacenters) and public cloud resources.
4
Identify the scenario utilizing multiple distinct public cloud providers for the same type of workload.
The mobile gaming studio matches the Multi-cloud model because it deploys across both Google Cloud Platform and Microsoft Azure.
Multi-cloud refers to using two or more public cloud services from different cloud providers.

Key Concept

Identifying and distinguishing between public, private, hybrid, and multi-cloud models based on ownership, infrastructure location, and provider usage.
