Which Azure cloud-service type gives the customer the MOST control over the operating system and runtime?
AFunction as a Service (FaaS / serverless)
BPlatform as a Service (PaaS)
CInfrastructure as a Service (IaaS)
DSoftware as a Service (SaaS)
Answer & Solution
Correct answer: C. Infrastructure as a Service (IaaS)
IaaS provides VMs, networks, and storage — the customer manages the OS, runtime, and app. PaaS hides the OS; SaaS hides everything but the app's data; FaaS hides even the runtime container.
