This article explains the three main cloud service models—Infrastructure as a Service, Platform as a Service, and Software as a Service—by defining each, illustrating their analogies, describing their typical applications, and outlining how to choose the right model for business needs.
Cloud computing delivers on‑demand, pay‑as‑you‑go resources through IaaS, PaaS, and SaaS layers, while edge computing extends these services toward devices to meet latency, bandwidth, and privacy demands, using lightweight K3s‑based clusters that address management, connectivity, and resource constraints for applications such as autonomous driving.
The article explains the three cloud computing service models—Infrastructure as a Service, Platform as a Service, and Software as a Service—detailing how each layer integrates resources, benefits users and providers, and fits into the overall resource‑integration hierarchy of cloud architecture.
