Explanation: No matter what form they come in, “services” are obtained or purchased by a cloud customer from a cloud service provider. Services can come in many forms–virtual machines, network configurations, hosting setups, and software access, just to name a few. Hosting and servers–or, with a cloud, more appropriately virtual machines–are just two examples of “services” that a customer would purchase from a cloud provider. “Customers” would never be a service that’s purchased.
