☁️ Free practice test question from: Cloud Native Architecture (KCNA)

Infrastructure as a Service (IaaS): IaaS provides the fundamental building blocks of computing infrastructure—virtual machines, networking, storage—over the internet. This gives the development team full control over the operating systems, the Kubernetes control plane, and the worker nodes. They can install, configure, and manage everything according to their specific needs.
****
Software as a Service (SaaS): SaaS delivers ready-to-use applications over the internet. Users don't manage any infrastructure, operating systems, or application logic. Examples include Salesforce or Google Workspace. This doesn't provide the control the team needs.  

Function as a Service (FaaS): FaaS is a serverless computing model where developers write and deploy individual functions that events are triggered by events. The cloud provider manages the underlying infrastructure. This is too granular and doesn't provide control over the Kubernetes cluster itself.  Examples are AWS Functions or Azure Functions.

Platform as a Service (PaaS): PaaS provides a platform for developing, running, and managing applications without managing the underlying infrastructure. While some PaaS offerings might include Kubernetes, they typically abstract away control of the control plane and worker nodes. This limits the customization the team requires. Examples are Heroku or Vercel.
