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

Four regional electric power utilities establish a shared cloud environment to store, analyze, and exchange real-time cyber threat intelligence. The infrastructure is exclusively shared among these specific organizations, customized to meet strict energy sector regulatory compliance standards, and managed jointly by the participating entities. Which of the following cloud deployment models BEST describes this environment?

  1. Community cloudAnswer
  2. B
    Public cloud
  3. C
    Private cloud
  4. D
    Infrastructure as a Service (IaaS)

Answer

Community cloud
A community cloud model is provisioned for exclusive use by a specific community of consumers from organizations that have shared concerns (such as mission, security requirements, policy, and compliance considerations). In this scenario, the electric utilities form a multi-organization group sharing specialized threat intelligence under identical regulatory requirements.

Step-by-Step Solution

1
Analyze the access scope and organizational relationship described in the scenario.
The infrastructure is restricted to a specific group of entities (four electric power utilities) with common industry concerns and compliance requirements.
Determining who holds access permissions and shares infrastructure management dictates the cloud deployment model.
2
Evaluate the cloud deployment model options against the identified organizational boundaries.
Infrastructure shared exclusively among a specific group of organizations with shared security and operational objectives defines a Community cloud.
Private cloud serves one organization, public cloud serves the general public/commercial market, and community cloud serves a multi-organizational affinity group.
