Episode 15 — Cloud Service Models — IaaS, PaaS, SaaS Compared

This episode compares the three primary cloud service models—Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS)—detailing their unique capabilities, responsibilities, and use cases. We explain how IaaS offers flexibility and control for custom environments, how PaaS simplifies application development without infrastructure management, and how SaaS delivers ready-to-use applications over the internet. Each model is evaluated for scalability, cost efficiency, and security implications.We also connect these models to the shared responsibility framework, explaining what the provider handles versus what the customer must secure and maintain. This knowledge is essential for both the exam and practical deployment decisions, where choosing the wrong model can lead to mismatched expectations and operational gaps.
