Cloud Computing Services Models – IaaS PaaS SaaS Explained
Cloud computing services provide on-demand, network access, scalability, and shared resources. The services enable managing, storing, and processing data online through the internet. There are three delivery models for the services. They are SaaS (Software as a Service), PaaS (Platform as a Service), and IaaS (Infrastructure as a Service), which are organised in a hierarchical structure with SaaS at the highest level serving the end-users, PaaS at the middle level serving the developers, and IaaS at the lowest level serving big organisations who need to outsource their basic IT operations and hardware maintenance.
