This is an example of what type of cloud environment?

a) IaaS (Infrastructure as a Service)
b) PaaS (Platform as a Service)
c) SaaS (Software as a Service)
d) DaaS (Database as a Service)

Answer 1

Option (A), The scenario where a company uses a cloud service for hardware and bandwidth but manages the OS, software, and configuration, is an example of Infrastructure as a Service (IaaS).

Step-by-step explanation:

If a company decides to use a cloud service to provide the physical hardware and bandwidth for setting up a web server farm, but retains responsibility for the operating system, software, and server configuration, this is a classic model of Infrastructure as a Service (IaaS). With IaaS, the cloud provider supplies the networking, storage, and virtual servers, but the client manages the operating system, applications, and runtime environments. This contrasts with Platform as a Service (PaaS), which also includes the operating systems and often a suite of development and deployment tools in the service, and Software as a Service (SaaS), where the provider manages everything up to and including the applications. Database as a Service (DaaS) refers to managed database services, which is not applicable in this scenario.
