Which of the following cloud models can be used to speed up the development of...

Platform as a Service (PaaS) is designed to accelerate software delivery by providing a managed platform that typically includes the operating system layer, runtime, middleware, databases, and developer tooling—so teams can focus on building the service rather than provisioning and maintaining infrastructure and OS components. This directly supports the goal of speeding development and delivery while integrating closely with OS-level services provided by the platform (e.g., runtime services, identity, logging, scaling, patching). CompTIA Project+ includes understanding cloud models as part of IT concepts that affect project delivery choices.

By comparison, SaaS is a finished application you consume (not a development platform). IaaS provides raw compute/storage/networking; you still manage the OS and much of the stack, which is slower for development acceleration. DaaS generally refers to delivering desktops or data services depending on context, but it is not the standard model for speeding application development via an integrated platform stack.

Therefore, PaaS best matches the scenario: it reduces setup/maintenance work, standardizes environments, and helps teams deliver software faster and more reliably.
