Episode 84: Cloud Models: SaaS, PaaS, IaaS, and XaaS for PMs

In this episode, we explain the primary cloud service models—Software as a Service (SaaS), Platform as a Service (PaaS), Infrastructure as a Service (IaaS)—and the broader category of Anything as a Service (XaaS). We define each model, its responsibilities, and typical use cases, with a focus on how they influence project cost, scalability, and maintenance responsibilities.

We also compare benefits and trade-offs, such as SaaS reducing infrastructure management but limiting customization, or IaaS offering flexibility with greater configuration requirements. Examples demonstrate when each model is appropriate based on project goals and constraints. This knowledge will support PK0-005 exam performance and informed decision-making in cloud-enabled projects.
