お客様は、クラウド サービスを展開する必要があり、基盤となる OS、データ、およびアプリケーションを完全に制御する必要があります。この要件を満たすクラウド モデルはどれですか?
正解:C
The cloud model that meets the requirement of having full control over the underlying OS, data and application is Infrastructure as a Service (IaaS). IaaS is a cloud service model that provides the customer with access to virtualized computing resources, such as servers, storage, and networks, over the internet. The customer can install, configure, and manage the OS, data, and application of their choice on the rented infrastructure, without having to worry about the maintenance or security of the physical hardware. IaaS offers the customer the highest level of flexibility and control over their cloud environment, compared to other cloud models such as Platform as a Service (PaaS) or Software as a Service (SaaS).
