Which service provides a platform for developing, running and managing application functionality for microservices?

• A. SaaS
• B. IaaS
• C. PaaS
• D. Function as a Service (FaaS)

Answer: (D)

This question spotlights how serverless platforms power microservice-style architectures by running small units of code on demand. Function as a Service provides a serverless environment where you deploy individual functions that are invoked in response to events. The platform handles provisioning, scaling, and runtime management, so you can focus on the function logic itself. In a microservices setup, each service can be represented by its own functions, developed, deployed, and scaled independently, and coordinated through events and APIs. That emphasis on executing discrete pieces of application functionality with minimal infrastructure management makes FaaS the best fit for this description. In contrast, SaaS delivers ready-made applications, IaaS offers raw infrastructure, and PaaS provides a broader app development platform that isn’t as tightly centered on function-level microservice execution.
