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

A clinical research organization (CRO) manages sensitive patient clinical trial data. To comply with strict national data sovereignty regulations, the database containing patient records must be hosted on physical servers owned by the CRO within their local facility. However, the CRO wants to run its computationally intensive statistical analysis models using on-demand virtual machine scale sets in Microsoft Azure to minimize costs. Which cloud model should the CRO adopt to meet these requirements?

  1. A
    Public cloud
  2. B
    Private cloud
  3. Hybrid cloudAnswer
  4. D
    Multi-cloud

Answer

Hybrid cloud
A hybrid cloud model is correct because it combines private on-premises infrastructure (to meet data sovereignty rules by keeping the database on physical servers inside the organization's local facility) with public cloud services (to run computationally intensive statistical analysis models on-demand in Microsoft Azure).

Step-by-Step Solution

1
Analyze the data residency and compliance requirements.
The patient records database must remain on physical servers owned by the organization within their local facility, which represents a private cloud or on-premises environment.
This is necessary to comply with national data sovereignty regulations.
2
Analyze the scaling and cost-efficiency requirements.
The computational analysis models need to run on-demand using public cloud resources in Microsoft Azure to minimize costs.
This utilizes public cloud virtual machine scale sets for flexible, on-demand compute power.
3
Select the cloud model that bridges these two environments.
A hybrid cloud model is selected because it enables the integration of on-premises private infrastructure with public cloud resources.
It allows the organization to keep sensitive database workloads local while scaling compute-heavy workloads in the public cloud.
