Answer choices
Why each option matters

Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
PaaS
Why it's wrong here
PaaS provides a runtime and development platform (e.g., Google App Engine) where developers build and deploy custom applications by managing code and data but not the underlying infrastructure. Google Workspace, however, is a fully finished, ready-to-use suite of end-user productivity applications—email, docs, calendar—that requires no code or custom application development. Choosing PaaS would be like renting a workshop to build furniture when the furniture is already delivered assembled.
- ✗
FaaS
Why it's wrong here
FaaS (Function-as-a-Service, such as Cloud Functions) executes discrete, event-driven code snippets in response to triggers (e.g., HTTP calls, Pub/Sub messages) and scales autonomously, with billing per invocation. Google Workspace does not run user-written functions or respond to arbitrary events; it is a persistent, interactive suite of applications with a graphical UI. Therefore, FaaS is conceptually wrong because Workspace is not an execution model but a finished application service.
- ✗
IaaS
Why it's wrong here
IaaS offers virtualized compute, storage, and networking resources (like Compute Engine VMs) that a customer configures and manages from the OS upward, including patching, security, and app installation. Google Workspace, by contrast, is a fully managed, browser-based solution where Google handles all infrastructure, scaling, and maintenance, and users simply access the apps via a browser or client. IaaS would incorrectly imply the customer builds and maintains the entire environment, whereas Workspace is consumed as a turnkey service.
- ✓
SaaS
Why this is correct
SaaS (Software-as-a-Service) is a software distribution model where applications are hosted and managed by a vendor, delivered over the internet, typically with a subscription fee, and require no local installation or infrastructure management. Google Workspace epitomizes SaaS: Google provides Gmail, Google Docs, Drive, and Meet as consistent, always-current services with high availability, data redundancy, and centralized admin controls, while subscribers use them directly. The user is not responsible for servers, operating systems, or application upkeep—exactly the SaaS value proposition.
