once services are established, the customer should be able to provision new users, services, virtual machines, etc. without involving the cloud service provider.
Small to medium sized businesses can leverage cloud-based services to get enterprise-class solutions on tighter budgets. There probably isn’t a cloud service offering that an SMB can build themselves on premise with the same budget.
Enterprises might be able to deploy IT solutions with equal capabilities to a cloudbased offering, but that doesn’t mean that they want to. Enterprises should focus on those things that they must deploy on-prem.
cloud services are typically accessed over the Internet, as opposed to being on an internal network accessible only over private connections.
customers’ needs may expand or contract, and the service will expand or contract with those needs.
