Cloud computing is the use of computing resources (hardware and software) that are delivered as a service over a network (typically the Internet). The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure it contains in system diagrams. Cloud computing entrusts remote services with a user's data, software and computation. A storage cloud provides storage services, while a compute cloud provides compute services. The authors describe the design of the Sector storage cloud and how it provides the storage services required by the Sphere compute cloud. A cloud can be a storage cloud that provides block or file based storage service or it can be a compute cloud that provides computational services.
