A Mumbai-based startup rents virtual servers, storage and networking from a cloud provider and installs its own operating system and applications on them. Which cloud service model is the startup using?
The startup is using Infrastructure as a Service. The provider supplies virtual servers, storage and networking, while the customer installs and manages its own operating system and applications on top, which is the defining feature of IaaS.
- ASoftware as a Service (SaaS)
- BInfrastructure as a Service (IaaS)Correct
- CPlatform as a Service (PaaS)
- DBusiness Process as a Service
Explanation
In IaaS the provider supplies virtualised compute, storage and network, while the customer manages the operating system and applications. In SaaS the provider manages the whole application, and in PaaS the provider also manages the operating system and runtime, so those fit less well here.
