Cloud and Edge Computing

Draft Recommendation ITU-T Y.3504 (formerly Y.DaaS-arch), "Functional Architecture for Desktop as a Service"

Recommendation ITU-T Y.3510 provides requirements for cloud computing infrastructure; these include the essential capabilities for processing, storage and networking resources, as well as the capabilities of resource abstraction and control.

Recommendation ITU-T Y.3511 describes the framework for interactions of multiple cloud service providers (CSPs), which is referred to as inter-cloud computing. Based on several use case, and after considering the different types of service offerings, this Recommendation describes the possible relationships (peering, federation or intermediary) among multiple CSPs. By introducing the concept of primary CSP and secondary CSP, the Recommendation further describes CSP interactions for the cases of federation and intermediary patterns. Finally, relevant functional requirements are derived.

Recommendation ITU-T Y.3512 describes the concept of Network as a Service (NaaS) and its functional requirements. It provides typical use cases of NaaS and specifies the functional requirements of three aspects, ranging from NaaS application, NaaS platform and NaaS connectivity which are based on the corresponding uses cases and cloud capabilities types.

Recommendation ITU-T Y.3515 provides Network as a Service (NaaS) functional architecture by specifying functionalities and functional components as well as reference points for the operation support system (OSS). This Recommendation also describes the mapping between functionalities and functional requirements of NaaS, relationship between the NaaS functional architecture and software-defined networking (SDN), and illustrated usage of SDN and network functions virtualisation (NFV) in support of the NaaS functional architecture.

Recommendation ITU-T Y.3516 specifies inter-cloud computing functional architecture, including functions and functional components, based on the inter-cloud computing framework specified in [ITU-T Y.3511]. The Recommendation builds upon the functional view of the cloud computing reference architecture [ITU-T Y.3502] and makes extensions to functional components with inter-cloud functions. This Recommendation also describes the mapping between functions and functional requirements of inter-cloud computing and examples of inter-cloud related reference points.

Recommendation ITU-T Y.3519 describes the functional architecture for big data as a service (BDaaS). The functional architecture is defined on the basis of the analysis of requirements and activities of cloud computing-based big data described in Recommendation ITU-T Y.3600.

Draft new Recommendation ITU-T Y.ccecm: "Cloud Computing - Requirements of edge cloud management"

Draft Recommendation ITU-T Y.ccgmfdc:"Global Management Framework of Distributed Cloud"

In accordance with the functional reference architecture of cloud computing that was defined in Recommendation ITU-T Y.3502, Recommendation ITU-T Q.3914 specifies the functional reference architecture of cloud computing according to Recommendation ITU-T Y.3500. This Recommendation provides a set of parameters that indicate the status and event of a cloud computing system, including resource layer, service layer and access layer.
