Episode 16 — IaaS, PaaS, SaaS: What to Use When

Understanding service models is central to both cloud strategy and the Google Cloud Digital Leader exam. This episode breaks down Infrastructure as a Service, Platform as a Service, and Software as a Service—commonly known as IaaS, PaaS, and SaaS—highlighting how each aligns with different business and technical needs. IaaS delivers virtualized computing resources such as servers and storage, giving teams maximum control over configuration. PaaS provides a managed platform for application development, reducing administrative overhead. SaaS delivers complete software solutions accessible through a browser or API, requiring no infrastructure management at all. Knowing when to use each model is crucial for optimizing cost, agility, and responsibility boundaries.We explore how decision-making shifts across these layers. For instance, a startup may choose SaaS tools to focus entirely on product development, while an enterprise modernizing legacy systems may adopt PaaS to streamline deployment. IaaS remains valuable for workloads needing custom configurations or compliance-specific isolation. Exam questions often describe scenarios requiring candidates to select the most appropriate model based on operational, security, or budget priorities. Understanding these distinctions enables clear, business-oriented reasoning about technology choices.
