This Recommendation describes functional architecture for cloud service brokerage (CSB). To provide the functional architecture for CSB, the CSB functions based on configurations which have been identified in [ITU-T Y.3506] are introduced. This Recommendation also provides the relationship between the CSB functional architecture and the cloud computing reference architecture in [ITU-T Y.3502].
Recommendation ITU-T F.743.8 specifies the requirements for a cloud computing platform supporting visual surveillance. Cloud computing is an emerging technology aimed at providing various computing services over the Internet. Using virtualization technology, a cloud computing platform realizes a ubiquitous and flexible shared resources pool that can be rapidly provisioned and released with minimal management effort or service-provider interaction based on the needs of users. By using the cloud computing technology, the visual surveillance system can conveniently manage various functional components and services, such as video distribution, video transcoding and intelligent video processing. This Recommendation provides the application scenarios and requirements for a cloud computing platform supporting a visual surveillance system.
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.
Recommendation ITU-T H.626.2 defines a cloud storage architecture in visual surveillance. Cloud storage enables the service users to have ubiquitous, convenient and on-demand network access to a shared pool of the configurable storage resources, which can be rapidly provisioned and released with the minimal management effort or service-provider interaction. Cloud storage can realize flexible and reliable data storage for large-scale visual surveillance and its components are modularized and allocated dynamically based on the real usage. This Recommendation provides the architecture, entities, reference points and service control flow for cloud storage in visual surveillance.
Recommendation ITU-T X.1603 analyses data security requirements for the monitoring service of cloud computing which includes monitoring data scope requirements, monitoring data lifecycle, security requirements of monitoring data acquisition and security requirements of monitoring data storage. Monitoring data scope requirements include the necessary monitoring scope that cloud service providers (CSPs) should provide to maintain cloud security and the biggest monitoring scope of CSPs. Monitoring data lifecycle includes data creation, data store, data use, data migrate, data present, data destroy and data backup. Monitoring acquisition determines security requirements of the acquisition techniques of monitoring service. Monitoring data storage determines security requirements for CSPs to store the monitoring data.
Recommendation ITU-T X.1642 provides generic operational security guidelines for cloud computing from the perspective of cloud service providers (CSPs). It analyses the security requirements and metrics for the operation of cloud computing. A set of security measures and detailed security activities for the daily operation and maintenance are provided to help CSPs mitigate security risks and address security challenges for the operation of cloud computing.
Recommendation ITU-T X.1641 provides generic security guidelines for the cloud service customer (CSC) data in cloud computing. It analyses the CSC data security lifecycle and proposes security requirements at each stage of the data lifecycle. Furthermore, Recommendation ITU-T X.1641 provides guidelines on when each control should be used for best security practice.
Recommendation ITU-T X.1601 describes the security framework for cloud computing. The Recommendation analyses security threats and challenges in the cloud computing environment, and describes security capabilities that could mitigate these threats and address security challenges. A framework methodology is provided for determining which of these security capabilities will require specification for mitigating security threats and addressing security challenges for cloud computing. Appendix I provides a mapping table on how a particular security threat or challenge is addressed by one or more corresponding security capabilities.

Recommendation ITU-T M.3371 defines the general and functional management requirements that support service management in a cloud-aware telecommunication management system (see Recommendation ITU-T M.3070) and provides a functional framework for service management in a cloud-aware telecommunication management system.
Recommendation ITU-T M.3372 introduces a functional framework and functional requirements for resource management in cloud-aware telecommunication management systems. It provides the composition of the functional framework and the functions of each component in the framework. In this Recommendation, the general background and status of cloud computing management are also analysed. The benefit of introducing a functional framework and functional requirements for resource management in cloud-aware telecommunication management systems is also explained.
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.
