Microsoft 365 FundamentalsDescribe cloud conceptsEasy
A small non-profit organization is considering migrating its internal file storage to Microsoft 365. They are particularly interested in a service model where the cloud provider manages the underlying infrastructure, operating systems, and applications, while the organization is primarily responsible for its data and user access. Which cloud service type best fits this description?
- 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: A. Software as a Service (SaaS)
Software as a Service (SaaS) is a cloud service model where the cloud provider hosts and manages the entire application stack, including the application software, runtime, operating system, and underlying infrastructure. Users access the application over the internet and are responsible only for their data and user access.
Why the other options are wrong
- B. FaaS is a subset of serverless computing, focusing on executing event-driven functions without managing servers.
- C. PaaS provides a development environment and runtime, but the user is responsible for the application code and data.
- D. IaaS provides virtualized computing resources, but the user is responsible for the OS, runtime, and applications.
