Difficulty: EasyCloud Architecture and Deployment Models

An organization plans to deploy a database solution in the cloud. The company requires the Cloud Service Provider (CSP) to manage hardware provisioning, operating system installation, and database engine maintenance, while the internal IT team retains control over database tables and user permissions. Which cloud service model should the organization select to meet these requirements?

  1. Platform as a Service (PaaS)Answer
  2. B
    Infrastructure as a Service (IaaS)
  3. C
    Software as a Service (SaaS)
  4. D
    Private Cloud Deployment

Answer

Platform as a Service (PaaS)
Platform as a Service (PaaS) abstracts away physical infrastructure, OS deployment, and software runtime patching, enabling the cloud provider to manage the platform environment while allowing the customer to maintain full ownership over data structures, schemas, and identity permissions.

Step-by-Step Solution

1
Analyze the management boundary described in the scenario
The Cloud Service Provider maintains the hardware, operating system, and database software binaries.
Determining which tier of the stack is vendor-managed establishes the service model tier.
2
Identify customer responsibilities
The customer manages data schemas, database contents, and access permissions.
Customer responsibility limited to application data and configuration aligns directly with PaaS.
