Microsoft 365 FundamentalsDescribe cloud conceptsHard
A company requires a cloud solution that offers dedicated physical servers for regulatory compliance and specific licensing requirements, while still leveraging the cloud provider's infrastructure. They need to maintain full control over the server's operating system and virtualization layer. Which cloud service type offers this level of control and isolation?
- APlatform as a Service (PaaS)
- BSoftware as a Service (SaaS)
- CFunction as a Service (FaaS)
- DInfrastructure as a Service (IaaS)
Show answer & explanationAnswer & explanation
Correct answer: D. Infrastructure as a Service (IaaS)
Infrastructure as a Service (IaaS) provides the fundamental computing resources, including virtual machines and networking, but allows the customer to maintain full control over the operating system, applications, and even the virtualization layer in some cases (like dedicated hosts), which is crucial for specific compliance and licensing needs.
Why the other options are wrong
- A. PaaS abstracts away the operating system and virtualization layer, which conflicts with the need for full control.
- B. SaaS offers no control over the underlying infrastructure.
- C. FaaS is a serverless model, offering even less control than PaaS over infrastructure.
Infrastructure as a Service (IaaS)
A cloud service model that provides fundamental computing resources such as virtual machines, storage, networks, and operating systems, giving users the highest level of control over their IT infrastructure.
- Users manage OS, applications, and data.
- Cloud provider manages physical infrastructure, virtualization.
- Offers flexibility for custom configurations and legacy applications.
Memory trick: IaaS: I'm in Charge of My Stuff.
