What does the term "service model" refer to in cloud computing?

The term "service model" in cloud computing specifically refers to the type of service offered by a cloud provider. This encompasses the different ways cloud services are delivered to users and typically includes categories like Infrastructure as a Service (IaaS), Platform as a Service (PaaS), and Software as a Service (SaaS). Each of these service models provides distinct functionalities, allowing users to select the model that best fits their needs based on the level of control and management they require over their resources.

Understanding the service model is crucial for organizations to determine which type of service aligns with their operational needs, cost considerations, and the technical skills of their team. For example, a company may choose IaaS for its flexibility and control, while another may opt for SaaS to minimize management overhead and focus on application usage rather than infrastructure maintenance. This adaptability makes the service model a foundational concept in the cloud computing landscape, directly impacting how businesses leverage technology for their operations.
