300-420 Question 320
Single answerA company is planning to deploy a new application to the cloud. The application requires full control over the operating system and the ability to customize the environment. However, the company also wants to minimize infrastructure management overhead. Which cloud service model and deployment type would best meet these requirements?
- A
Infrastructure as a Service (IaaS) in a public cloud deployment
- B
Platform as a Service (PaaS) in a hybrid cloud deployment
- C
Software as a Service (SaaS) in a private cloud deployment
- D
Infrastructure as a Service (IaaS) in a private cloud deployment
Show answer and explanation
Correct answer: A
Explanation
The company requires a solution that provides full control over the operating system and environment while minimizing infrastructure management overhead. Infrastructure as a Service (IaaS) in a public cloud deployment fulfills these requirements by offering control over virtualized resources (e.g., VMs, storage, and networks) and outsourcing hardware management to the cloud provider, making it the best fit for this scenario.
- A. Correct.
IaaS in a public cloud deployment provides control over the operating system, storage, and network configurations while minimizing infrastructure management by outsourcing physical hardware to the cloud provider. This aligns with the requirements.
- B. Incorrect.
PaaS focuses on providing a platform for application development and abstracts much of the control over the operating system and environment, which does not meet the need for full control.
- C. Incorrect.
SaaS provides ready-to-use software applications and does not allow control over the underlying operating system or environment, making it unsuitable for the scenario.
- D. Incorrect.
IaaS in a private cloud deployment also provides control over the operating system and environment, but it involves significant infrastructure management overhead, which is not desired in this case.
