Intercloud and interoperability 5

1 Scope
This Recommendation specifies a framework of trusted inter-cloud computing and relevant use cases, based
on the framework of inter-cloud computing [ITU-T Y.3511]. The scope of this Recommendation includes:
– an overview of trusted inter-cloud computing;
– general requirements for trusted inter-cloud;
– requirements for governance of trusted inter-cloud;
– requirements for management of trusted inter-cloud;
– requirements for resiliency of trusted inter-cloud;
– requirements for security and confidentiality of trusted inter-cloud.
