CPA · Question 01 · Area I: Information Systems
A CPA is advising a client who is migrating their legacy on-premise ERP system to a cloud-based solution. The client wants to minimize their internal IT team's responsibility for managing the underlying operating system, middleware, and runtime environment, but they want to retain control over the deployed applications and configuration settings. Which cloud service model is MOST appropriate for this client?

Answer options:
A.
Infrastructure as a Service (IaaS)
B.
Platform as a Service (PaaS)
C.
Software as a Service (SaaS)
D.
Function as a Service (FaaS)
How to approach this question
Identify the specific layer of the IT stack the client wants to control versus offload. PaaS sits between IaaS (more control) and SaaS (less control).
Full Answer
B.Platform as a Service (PaaS)✓ Correct
In a Platform as a Service (PaaS) model, the cloud provider manages the infrastructure (servers, storage, networking) as well as the operating system, middleware, and runtime. The customer is responsible for the applications and data deployed on top of that platform.
Common mistakes
Confusing IaaS (where you manage the OS) with PaaS.
