Which term completes the cloud service model phrase 'Platform as a Service'?

• A. Platform
• B. Software
• C. Infrastructure
• D. Function

Answer: (A)

Understanding how cloud service models are named helps: the “X as a Service” naming shows what is provided as a service and what the provider manages. Platform as a Service describes a cloud offering that supplies a ready-made platform—including runtime, development tools, and middleware—for building and running applications, so you don’t have to manage the underlying hardware or OS. The term that completes the phrase is Platform, because this model is part of the well-known trio: Infrastructure as a Service, Platform as a Service, Software as a Service. The other options would complete different service models—Software for SaaS, Infrastructure for IaaS—and Function belongs to another pattern that isn’t part of the standard trio.
