HR adopts a cloud payroll application that staff use in a browser with no servers for HR to manage. Which cloud service type is that?
Select an answer to reveal the explanation.
Short Explanation
Browser payroll with zero servers on HR’s chore list is textbook SaaS — the finished app arrives as a service. If HR were patching VMs, that would be IaaS instead. Colocation cages are still your hardware problem.
Full Explanation
SaaS delivers a complete application as a service, typically consumed through a client such as a browser, with the provider managing the underlying infrastructure and application stack. HR payroll in that model is a classic SaaS example. IaaS would leave infrastructure and OS duties with the customer; colocation is not SaaS.
