1 Framework and requirements for cloud computing

1 Scope
This Recommendation provides a cloud computing framework by identifying high-level requirements for
cloud computing. The Recommendation addresses the general requirements and use cases for:
– Cloud computing;
– Infrastructure as a service (IaaS), network as a service (NaaS), desktop as a service (DaaS), platform
as a service (PaaS), communication as a service (CaaS) and big data as a service (BDaaS);
– Inter-cloud computing, end-to-end cloud computing management, trusted cloud service, and cloud
infrastructure.
This Recommendation addresses a set of use cases and related requirements which are included in
Appendix I. Appendix II provides information on the methodology and edition plan of this Recommendation.
