Question

Difficulty: MediumCloud Deployment Models (Public, Private, Hybrid, Community)

A coalition of three independent oceanographic research institutes collaborates under a shared governance agreement to maintain an ocean climate modeling infrastructure. The underlying hardware is jointly funded, owned, and restricted exclusively to these member institutes. Additionally, to handle brief seasonal surges in telemetry processing, the coalition automatically bursts temporary workloads to a multi-tenant cloud infrastructure accessible to the general public. Which TWO cloud deployment models are directly combined in this infrastructure solution? (Select TWO.)

  1. Community cloudAnswer
  2. Public cloudAnswer
  3. C
    Private cloud
  4. D
    Software as a Service (SaaS)

Answer

The infrastructure solution combines a Community cloud (shared exclusively among specific collaborating member institutes) with a Public cloud (multi-tenant third-party infrastructure used for seasonal workload bursting).
The scenario describes two distinct deployment environments being integrated: first, a shared infrastructure funded and used exclusively by a consortium of independent oceanographic institutes with a common purpose, which is the definition of a Community cloud; second, an externally hosted multi-tenant cloud utilized for on-demand cloud bursting, which represents a Public cloud.

Step-by-Step Solution

1
Analyze the primary joint infrastructure operated by the research institutes.
Identified that the hardware is shared exclusively among specific independent organizations bound by common research goals and shared governance.
Infrastructure shared among a specific group of organizations with common interests defines a Community cloud.
2
Analyze the secondary infrastructure used for handling temporary processing surges.
Identified that workloads burst into a multi-tenant cloud environment accessible to the general public and managed by an external provider.
Multi-tenant cloud infrastructure open to external public access defines a Public cloud.
3
Differentiate deployment models from service models and single-tenant architectures.
Excluded Private cloud (which serves a single entity exclusively) and SaaS (which is a service model rather than a deployment model).
The question specifically asks for the two deployment models being integrated.
