A company is migrating its on-premises virtual machines to a cloud provider. They want to maintain control over the operating system, applications, and middleware, but outsource the management of the underlying physical servers, storage, and networking hardware. Which cloud service model are they utilizing?
- AFunction as a Service (FaaS)
- BPlatform as a Service (PaaS)
- CInfrastructure as a Service (IaaS)
- DSoftware as a Service (SaaS)
Show answer & explanationAnswer & explanation
Correct answer: C. Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) provides virtualized computing resources over the internet, allowing users to manage their operating systems, applications, and middleware, while the cloud provider manages the underlying infrastructure.
Why the other options are wrong
- A. FaaS is a serverless execution model, where users only manage code, not entire VMs or OS.
- B. PaaS provides a development platform; users manage applications and data, but not the OS or middleware.
- D. SaaS provides a complete application; users have no control over the OS or middleware.
Infrastructure as a Service (IaaS)
A cloud service model that provides virtualized computing resources over the internet, including virtual machines, storage, and networks, with the user managing the operating system and applications.
- Cloud provider manages virtualization, servers, storage, networking.
- User manages operating systems, applications, middleware.
- Offers high flexibility and control over infrastructure.
Memory trick: IaaS is like getting a 'barebones' computer; you install the OS and software.
