Standard

The present document provides a list of features which the performance and portability templates (Virtual Machine Descriptor and Compute Host Descriptor) should contain for the appropriate deployment of Virtual Machines over a Compute Host (i.e. a "telco datacentre").
 
In addition, the document provides a set of recommendations and best practises on the minimum requirements that the HW and hypervisor should have for a "telco datacentre" suitable for data-plane workloads. The recommendations and best practises are based on tests results from the performance evaluation of data-plane workloads. It is recognized that the recommendations are required for VNFs supporting data plane workloads and that a small portion of the recommended list are not required in all cases of VNFs, such as VNFs related to control plane workloads.

Use case and functional requirements for Inter-Cloud Computing (The Global Inter-Cloud Technology Forum is discontinued).

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.
 
Following the methodology of Recommendation ITU-T Y.3502, the BDaaS functional architecture is described from a set of functional components and cross-cutting aspects. The specified functional components consist of sets of functions that are required to perform the BDaaS activities for the roles and sub-roles described in Recommendation ITU-T Y.3600.

Cloud computing is a paradigm for enabling network access to a scalable and elastic pool of shareable physical or virtual resources with self-service provisioning and administration on-demand. The cloud computing paradigm is composed of key characteristics, cloud computing roles and activities, cloud capabilities types and cloud service categories, cloud deployment models and cloud computing cross cutting aspects.

This Recommendation | International Standard provides an overview of cloud computing, and defines related terms.
The terms and definitions provided in this Recommendation | International Standard:
– cover commonly used terms and definitions in cloud computing standards;
– will not cover all terms and definitions used in cloud computing standards; and
– do not preclude the definition of additional terms for use in cloud computing standards.

Recommendation ITU-T Y.3513 introduces the concept of Infrastructure as a Service (IaaS) and describes its functional requirements. As one of the cloud computing service categories, Infrastructure as a Service provides cloud service customers with computing, storage and network services by cloud service providers. To derive those requirements, relevant use cases are also presented.

This Recommendation specifies a framework of trusted inter-cloud computing and relevant use cases. It provides general requirements for trusted inter-cloud and specific ones related to governance, management, resiliency, security and confidentiality of trusted inter-cloud. The inter-cloud computing concept is based on the relationship (pattern) among multiple cloud service providers (CSPs). This pattern (peering, federation or intermediary) allows the CSP to interwork with one or more peer CSPs to assure intermediation and security of services provided by these CSPs.

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.3517 provides an overview of inter-cloud trust management by specifying isolation and security management mechanisms, inter-cloud trust management model, reputation-based trust management in an inter-cloud environment, cloud service evaluation framework and the relationship with cloud computing reference architecture. It also provides requirements for inter-cloud trust management derived from the corresponding use cases.

Recommendation ITU-T Y.3520 presents general concepts of end to end resource management in cloud computing; a vision for adoption of cloud resource management in a telecommunication-rich environment; and multi-cloud, end to end resource management for cloud services, i.e., management of any hardware and software used in support of the delivery of cloud services.
