Harbour Logistics, a regional freight firm, replaces its in-house servers with a provider's platform where it rents virtual machines, storage and networking, but still installs and manages its own operating systems and applications. Which cloud service model is Harbour Logistics using?
Harbour Logistics is using infrastructure as a service. It rents virtual machines, storage and networking from the provider but remains responsible for operating systems and applications, which is the defining feature of IaaS rather than platform or software services.

Explanation
Renting virtual machines, storage and networking while managing operating systems and applications is infrastructure as a service. In SaaS the provider runs the application, and in PaaS the provider also manages the operating system and runtime environment, so those options give the customer less control than described.
