The characteristic of cloud computing that allows for computing power, storage, and network services to be provisioned without human interaction is on-demand self-service. This feature enables users to automatically provision and manage resources as needed without requiring direct involvement from the service provider’s staff. It empowers users to access resources through a web-based interface or APIs, facilitating an efficient and immediate response to resource needs.

On-demand self-service is fundamental for organizations looking to scale operations quickly and efficiently. By enabling users to control the services they use independently, this characteristic supports agility and responsiveness to changes in demand without cumbersome delays that might arise from needing human intervention for each request.

Other characteristics, while important, focus on different aspects of cloud computing. Broad network access refers to the ability to access cloud services over the internet from various devices, while resource pooling addresses the provider's capability to serve multiple customers by aggregating resources. Rapid elasticity pertains to the ability to quickly scale resources up or down as required. However, none directly enable the provision of resources without human interaction like on-demand self-service does.
