On-demand service is one of the major characteristics of cloud computing. It is a business computing model in which computing resources are made available to the user on an “as needed” basis and the user needs to pay only for the amount of resources that he/ she requires.
Like any other services, cloud also has its cloud service provider. So to use cloud the user needs to pay for the amount of storage, resources he/ she wants; to the cloud service provider. Then the cloud service provider gives access to the user for the same.
