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

An enterprise is evaluating deployment options for several new IT workloads. Which cloud model corresponds to each of the business scenarios described?

  • A startup deploys its web analytics platform across multiple tenant-shared environments managed entirely by a third-party vendor, accessed securely over the public internet.Public cloud
  • A government organization rents dedicated physical servers located in a third-party datacenter to host its sensitive records, ensuring that no other organization shares the hardware or network infrastructure.Private cloud
  • A financial institution retains its core transaction database on its local on-premises hardware due to legacy compatibility, while utilizing a public cloud platform to run high-performance risk-modeling simulations that query the local database.Hybrid cloud
  • A software development firm deploys its database services on one public cloud provider to utilize a specific managed SQL service, while hosting its machine learning workloads on a different public cloud provider to take advantage of specialized AI tools.Multi-cloud

Answer

The startup's tenant-shared web analytics platform matches the public cloud model. The government organization's dedicated servers in a third-party datacenter match the private cloud model. The financial institution's combined on-premises database and public cloud simulations match the hybrid cloud model. The software firm's use of two different public cloud providers matches the multi-cloud model.
The correct matches align each scenario to the cloud model that matches its hosting ownership, tenancy, and structure: public cloud is represented by tenant-shared environments; private cloud is represented by dedicated physical servers rented from a third-party provider; hybrid cloud is represented by integrating on-premises hardware with public cloud simulations; and multi-cloud is represented by distributing workloads across two distinct public cloud providers.

Step-by-Step Solution

1
Analyze the startup's scenario involving tenant-shared environments managed by a third-party vendor over the internet.
Identify this as the public cloud model.
Public cloud resources are owned by a third-party provider, shared among multiple tenants, and accessed over the internet.
2
Analyze the government organization's scenario involving rented, dedicated physical servers inside a third-party datacenter with no shared hardware.
Identify this as the private cloud model.
Private cloud consists of computing resources used exclusively by one business or organization, which can be physically located at the organization's on-site datacenter or hosted by a third-party service provider.
3
Analyze the financial institution's scenario combining local on-premises hardware with public cloud risk-modeling simulations.
Identify this as the hybrid cloud model.
Hybrid cloud combines public and private cloud environments (such as on-premises infrastructure), allowing data and applications to be shared between them.
4
Analyze the software firm's scenario deploying database services on one public cloud and machine learning on another public cloud.
Identify this as the multi-cloud model.
Multi-cloud refers to the use of multiple public cloud services from different cloud providers, without necessarily integrating them into a hybrid model.
