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.

Recommendation ITU-T M.3071 introduces a new network management functional architecture with cloud-computing technology. In this Recommendation, the background and basic concept of cloud-based network management are provided. This Recommendation also provides details of a cloud-based network management functional architecture, including its basic components, functionalities and the relationship between its components.

This Recommendation describes the framework of risk management in cloud computing, including risk assessment, risk treatment, risk acceptance, risk communication, risk monitoring and review, etc. It focuses on the risk management processes of CSP.

Recommendation ITU-T X.1631 | ISO/IEC 27017 provides guidelines for information security controls applicable to the provision and use of cloud services by providing:

• additional implementation guidance for relevant controls specified in ISO/IEC 27002;
• additional controls with implementation guidance that specifically relate to cloud services.

This Recommendation | International Standard provides controls and implementation guidance for both cloud service providers and cloud service customers.

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 F.743.2 defines the cloud storage service requirements in visual surveillance. Cloud storage enables service users to have ubiquitous, convenient, on-demand network access to a shared pool of configurable storage resources, which can be rapidly provisioned and released with 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 real usage. This Recommendation provides the application scenarios and requirements for cloud storage in visual surveillance.

ITU-T Study Group 11 (SG11) is responsible for 'signalling', producing international standards (ITU-T Recommendations) that define how telephone calls and other calls (such as data calls) are handled in the network.
 
SG11 is home to Signaling System 7 (SS7), the set of signalling protocols that underpins telephone calls in both fixed and mobile networks, without which telecom systems around the world would not interoperate. All telephone switching systems need signalling. It provides the means for monitoring the status of a line to see if it is busy or idle, the alerts that indicate the arrival of a call, and the addressing system that routes calls. Before SS7's implementation, not all nations were party to the standards agreements enabling international telephone calls. SS7's implementation thus paved the way for the efficient operation of international telecommunication networks.
 
SG11 is tasked with developing signalling requirements and protocols for Software-defined Networking (SDN), and this work aligns with the functional requirements and architectures developed by ITU-T Study Group 13 (Future networks). Considered a major shift in networking technology, SDN will give network operators the ability to establish and manage new virtualized resources and networks without deploying new hardware technologies. ICT market players see SDN and network virtualization as critical to countering the increases in network complexity, management and operational costs traditionally associated with the introduction of new services or technologies.
 
SG11 is also responsible for the development of test specifications. This work focuses on global interoperability testing and covers technical means, services, quality of service (QoS) and testing parameters. Activities encompass establishing benchmark testing procedures and investigating the testing of next-generation networks (NGN), ubiquitous sensor networks (USN) and emerging technologies such as the internet of things (IoT), distributed service network (DSN), home networking (HN), etc.
 
SG11 leads ITU’s work on conformance and interoperability (C&I) testing and is responsible for coordinating ITU’s C&I programme. Conformance with international standards is one of the core principles underlying the global interoperability of ICT networks and devices. The C&I programme was initiated at the request of ITU’s membership in light of the challenges faced by developing countries in improving interoperability. The programme rests on four central pillars: conformance assessment; interoperability events; human resource and capacity building; and assistance in the establishment of test facilities in developing countries. SG11 is also investigating whether the ITU C&I programme could play a role in battling counterfeit goods.
 
When meeting at ITU headquarters in Geneva, SG11 holds its meetings in collocation with SG13.

Cloud interoperability for web applications refers to the interaction between the cloud service customer (CSC) and the cloud service provider (CSP) to obtain predictable results, collaboration among different web applications and consistency and interoperability of a management interface across different web applications.
 
Recommendation ITU-T Q.4042.1, which is part 1, specifies the cloud interoperability test objectives for web applications between the CSC and CSP.
 
These test objectives are developed on the basis of cloud computing interoperability testing objectives specified in Recommendation ITU-T Q.4040. The test cases for cloud interoperability testing for web applications are also introduced in the appendices.

Recommendation ITU-T Q.4041.1 specifies the cloud computing infrastructure capabilities type interoperability testing between the CSC and CSP, including interoperability testing of computing services, storage services, network services and related management functions, based on the functional requirements specified in Recommendation ITU-T Y.3513. The test cases of cloud computing infrastructure capabilities type interoperability testing between the CSC and CSP have also been introduced.
