Explanation:

According to the NIST definition, cloud computing is a model for enabling ubiquitous, convenient, on-demand network access to a shared pool of configurable computing resources (e.g., networks, servers, storage, applications, and services) that can be rapidly provisioned and released with minimal management effort or service provider interaction1.One of the essential characteristics of cloud computing is on-demand self-service, which means that users can request and obtain computing resources as needed, without requiring human intervention from the service provider2.On-demand network services are an example of this characteristic, as they allow users to access network resources such as bandwidth, routing, firewall, or load balancing, on demand and in a scalable manner3.Reference:
