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

A healthcare provider plans to deploy a new patient portal that requires rapid, automated scaling to support unpredictable spikes in user traffic. At the same time, the provider must retain a legacy medical database on dedicated physical hardware inside its own on-premises datacenter to comply with local healthcare privacy regulations. The patient portal must securely access this legacy database. The provider wants to minimize upfront capital expenditures (CapEx) for the portal's infrastructure while maintaining ownership and control of the database hardware. Which cloud deployment model should the provider implement to satisfy these requirements?

  1. A
    A public cloud model
  2. A hybrid cloud modelAnswer
  3. C
    A private cloud model
  4. D
    A Software as a Service (SaaS) model

Answer

A hybrid cloud model
A hybrid cloud model combines public cloud resources (which provide elastic scaling and minimize CapEx for the patient portal) with private infrastructure or on-premises datacenters (which satisfy the requirement to host the legacy database on dedicated, owned physical hardware). This allows both systems to interact securely while meeting all business, financial, and compliance constraints.

Step-by-Step Solution

1
Analyze the infrastructure requirements for the patient portal.
The portal needs rapid, automated scaling and low upfront costs (minimizing CapEx), which aligns with the benefits of a public cloud model.
This determines the cloud environment characteristics required for the web-facing tier.
2
Analyze the infrastructure requirements for the legacy database.
The database must reside on dedicated physical hardware within the provider's own datacenter for compliance, which represents an on-premises or private cloud model.
This determines the cloud environment characteristics required for the data tier.
3
Combine the requirements and identify the intersecting model.
Connecting the public cloud-hosted patient portal with the on-premises database represents a hybrid cloud model.
A hybrid cloud model integrates public cloud services with private, on-premises infrastructure, allowing data and applications to be shared between them.

Key Concept

Cloud deployment models, specifically the hybrid cloud model which bridges public cloud services with on-premises or private infrastructure.
