Question

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

An organization is planning to deploy different IT workloads to the cloud. Match each business scenario to the cloud model that best describes its deployment.

  • Public cloudAn online booking startup deploys its API and front-end interface on Azure App Services, utilizing Azure's global infrastructure without owning or managing physical hardware.
  • Private cloudA medical research center processes highly sensitive genomic data on physical servers located within its own datacenter to ensure total regulatory control.
  • Hybrid cloudA manufacturing firm runs its primary assembly line control system on local physical servers in its factories while using Azure Synapse Analytics for aggregated historical reporting.
  • Multi-cloudA logistics company hosts its GPS vehicle tracking service on one public cloud provider and its supply-chain predictive analytics on a different public cloud provider, with no on-premises infrastructure.

Answer

Public cloud matches the online booking startup; Private cloud matches the medical research center; Hybrid cloud matches the manufacturing firm; Multi-cloud matches the logistics company.
Matching Public cloud with the online booking startup is correct because it uses third-party public cloud services (Azure App Services). Matching Private cloud with the medical research center is correct because the research center hosts workloads on dedicated hardware in its own datacenter. Matching Hybrid cloud with the manufacturing firm is correct because it combines local physical servers (on-premises) with public cloud analytics (Azure Synapse Analytics). Matching Multi-cloud with the logistics company is correct because it distributes workloads across two distinct public cloud providers (AWS and Azure) without utilizing on-premises infrastructure.

Step-by-Step Solution

1
Analyze the online booking startup scenario where all resources run on Azure App Services without local hardware.
Identify this as the public cloud model because the infrastructure is entirely managed and owned by a third-party provider.
Public cloud resources are shared multi-tenant infrastructures owned by cloud providers.
2
Analyze the medical research center scenario which uses dedicated physical servers inside its own datacenter.
Identify this as the private cloud model because the organization has exclusive use of the dedicated hardware in its own facility.
Private clouds feature dedicated infrastructure owned and used solely by one organization.
3
Analyze the manufacturing firm scenario that combines local physical factory servers with Azure Synapse Analytics.
Identify this as the hybrid cloud model since it integrates on-premises infrastructure with public cloud services.
Hybrid cloud is defined by the coexistence and integration of private/on-premises systems with public cloud platforms.
4
Analyze the logistics company scenario that utilizes two distinct public cloud providers with no local servers.
Identify this as the multi-cloud model because the company distributes services across multiple public cloud vendors.
Multi-cloud refers to deploying assets across multiple public cloud providers to distribute risk or utilize specific services.

Key Concept

Cloud deployment models determine where data is stored and where applications run, categorized into public, private, hybrid, and multi-cloud environments.
