CompTIA Cloud Essentials+ (CLO-002)Cloud ConceptsEasy
A software development team requires a cloud environment where they can quickly provision virtual machines, storage, and networking components. They need full administrative control over the operating systems and installed software, but they don't want to manage the underlying physical hardware. Which cloud service model is most appropriate for their needs?
- ASoftware as a Service (SaaS)
- BFunction as a Service (FaaS)
- CPlatform as a Service (PaaS)
- DInfrastructure as a Service (IaaS)
Show answer & explanationAnswer & explanation
Correct answer: D. Infrastructure as a Service (IaaS)
IaaS provides virtualized computing resources like VMs, storage, and networks, giving users full control over the OS and applications, while the cloud provider manages the physical infrastructure. This aligns with the team's need for control without hardware management.
Why the other options are wrong
- A. SaaS delivers complete applications; users have no control over the underlying OS or infrastructure.
- B. FaaS is a subset of PaaS, focusing on event-driven functions, and does not provide administrative control over full operating systems.
- C. PaaS provides a development platform; users manage applications but not the OS or underlying infrastructure.
Infrastructure as a Service (IaaS)
A cloud computing service model that provides virtualized computing resources over the internet. IaaS allows users to manage their own operating systems, applications, and data, while the cloud provider manages the underlying infrastructure.
- Cloud provider manages physical infrastructure, virtualization, networking, and storage.
- User manages operating systems, middleware, applications, and data.
- Offers the most flexibility and control over computing resources.
