Oracle Cloud Infrastructure Foundations 2020 Associate — Question 15
A customer wants to deploy a customized e-commerce web application using multiple virtual machines, block storage, databases, load balancer and a web application firewall.
What cloud model can be used to host this application?
Answer options
- A. Infrastructure as a Service (IaaS)
- B. Software as a Service (SaaS)
- C. Platform as a Service (PaaS)
- D. Anything as a Service (XaaS)
Correct answer: A
Explanation
Infrastructure as a Service (IaaS) is the correct choice because it provides the necessary resources such as virtual machines, storage, and networking components required for deploying a customized application. Software as a Service (SaaS) delivers software applications over the internet, while Platform as a Service (PaaS) offers a platform for building applications but may not provide the level of customization needed for infrastructure. Anything as a Service (XaaS) is a broad term that doesn't specifically address the infrastructure needs outlined in the question.
