Microsoft 365 FundamentalsDescribe cloud conceptsMedium
A software development company wants to set up a testing environment quickly for a new project. They need control over the operating system and network configuration, but they don't want to manage the underlying physical servers or networking hardware. Which cloud service type is most suitable for their needs?
- ASoftware as a Service (SaaS)
- BPlatform as a Service (PaaS)
- 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 virtualized computing resources over the internet, giving users control over operating systems, applications, and network components, while the cloud provider manages the underlying physical infrastructure.
Why the other options are wrong
- A. SaaS provides ready-to-use applications, offering no control over OS or network.
- B. PaaS provides a development environment, abstracting OS and infrastructure, which is less control than requested.
- C. FaaS (serverless) executes code in response to events, with even less control over the underlying infrastructure than PaaS.
Infrastructure as a Service (IaaS)
A cloud service model that provides virtualized computing resources over the internet, including virtual machines, networks, and storage.
- Users manage operating systems, applications, and data.
- Cloud provider manages virtualization, servers, storage, and networking hardware.
- Offers the most control among cloud service models (SaaS, PaaS, IaaS).
Memory trick: I-P-S: I control Infrastructure, Platform handles, Software is ready.
