Question

what is on-demand service? how it is provided in cloud computing?​

Answer 1

Answer:

On-demand computing is a business computing model in which computing resources are made available to the user on an “as needed” basis. Rather than all at once, on-demand computing allows cloud hosting companies to provide their clients with access to computing resources as they become necessary.

Answer 2

Answer:

On-demand self-service means that a consumer can request and receive access to a service offering, without an administrator or some sort of support staff having to fulfill the request manually. The request processes and fulfillment processes are all automated.
