3 Definitions

3.1 Terms defined elsewhere

This Recommendation uses the following terms defined elsewhere:
3.1.1 interoperability [ITU-T Y.101]: The ability of two or more systems or applications to exchange
information and to mutually use the information that has been exchanged.

3.1.2 interworking [ITU-T Y.1401]: The term ''interworking'' is used to express interactions between
networks, between end systems, or between parts thereof, with the aim of providing a functional entity
capable of supporting an end-to-end communication.
3.1.3 cloud service provider (CSP) [ITU-T Y.3500]: Party which makes cloud services available.

3.1.4 cloud service customer (CSC) [ITU-T Y.3500]: Party which is in a business relationship for the
purpose of using cloud services.

3.2 Terms defined in this Recommendation

This Recommendation defines the following terms:
3.2.1 cloud interoperability: The capability to interact between CSCs and CSPs or between different CPSs,
including the ability of CSCs to interact with cloud services and exchange information, the ability for one
cloud service to work with other cloud services, and the ability for CSCs to interact with the cloud service
management facilities of the CSPs.
