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

A company is evaluating different cloud deployment models to host its workloads. Match each business scenario to its corresponding cloud model.

  • Public cloudA municipal government hosts its public-facing community forum on shared infrastructure operated by a third-party service provider.
  • Private cloudA financial firm hosts its highly sensitive transaction ledger on dedicated hardware located inside its own physical headquarters.
  • Hybrid cloudA retail company hosts its legacy inventory database in an on-premises data center while scaling its web front-end on global cloud servers.

Answer

Public cloud matches the municipal government hosting a public forum on shared third-party infrastructure. Private cloud matches the financial firm hosting its ledger on dedicated hardware in its own headquarters. Hybrid cloud matches the retail company hosting its legacy inventory database on-premises while scaling its web front-end on public cloud servers.
The correct pairings map each scenario to the cloud model that governs its infrastructure ownership and sharing. Public cloud uses shared infrastructure managed by a third party; private cloud uses dedicated infrastructure exclusive to one organization; hybrid cloud blends both environments.

Step-by-Step Solution

1
Analyze the municipal government scenario.
The scenario describes using shared infrastructure owned by a third party, which matches the definition of a public cloud.
Public cloud resources are multi-tenant and managed by the cloud provider.
2
Analyze the financial firm scenario.
The scenario describes hosting workloads on dedicated hardware in their own headquarters, which matches the definition of a private cloud.
Private cloud offers dedicated resource usage and complete control over physical hardware.
3
Analyze the retail company scenario.
The scenario describes a mix of on-premises resources (for legacy inventory) and public cloud resources (for the web front-end), which matches the definition of a hybrid cloud.
Hybrid cloud bridges on-premises/private cloud and public cloud environments.

Key Concept

Cloud deployment models define where data is stored and how infrastructure is shared, categorized into public, private, and hybrid models.
