Continuity management (or business continuity management) is focused on planning for the successful restoration of systems or services after an unexpected outage, incident, or disaster.

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.
