A company wants to rent software over the internet on a subscription basis, with the supplier hosting, maintaining and updating the application. Which cloud service model does this describe?
This is software as a service. The supplier hosts, maintains and updates the application, and the customer accesses it over the internet for a subscription fee. IaaS only supplies computing infrastructure and PaaS supplies a development environment, so neither describes renting a ready-made application.
- AInfrastructure as a service (IaaS)
- BPlatform as a service (PaaS)
- CSoftware as a service (SaaS)Correct
- DData as a service (DaaS)
Explanation
Under SaaS the supplier hosts and maintains the application and customers access it via the internet, usually by subscription. IaaS provides only virtual hardware such as servers and storage, and PaaS provides a development platform, so neither matches renting a finished application.
