Explanation

In the SaaS (Software as a Service) model, the cloud provider manages everything: hardware infrastructure, operating systems, middleware, and the application itself. Customers consume the software as-is and have no ability to modify the application code, choose the underlying infrastructure, control update schedules, or customize the environment deeply. This lack of control is the defining trade-off of SaaS. Option A is incorrect because SaaS eliminates large upfront CapEx - costs are operational (subscription-based). Option B is incorrect because SaaS is accessed via a browser or thin client, removing the need for local hardware upgrades. Option D (data integration complexity) is a real SaaS concern but it is a secondary operational challenge, not the primary or defining one - loss of control over the application and infrastructure is the foundational challenge that distinguishes SaaS from IaaS or PaaS.
