ITU-T Y.3520 (09/2015) FOREWORD The International Telecommunication Union (ITU) is the United Nations specialized agency in the field of telecommunications, information and communication techno
11、logies (ICTs). The ITU Telecommunication Standardization Sector (ITU-T) is a permanent organ of ITU. ITU-T is responsible for studying technical, operating and tariff questions and issuing Recommendations on them with a view to standardizing telecommunications on a worldwide basis. The World Telecom
12、munication Standardization Assembly (WTSA), which meets every four years, establishes the topics for study by the ITU-T study groups which, in turn, produce Recommendations on these topics. The approval of ITU-T Recommendations is covered by the procedure laid down in WTSA Resolution 1. In some area
13、s of information technology which fall within ITU-Ts purview, the necessary standards are prepared on a collaborative basis with ISO and IEC. NOTE In this Recommendation, the expression “Administration“ is used for conciseness to indicate both a telecommunication administration and a recognized oper
14、ating agency. Compliance with this Recommendation is voluntary. However, the Recommendation may contain certain mandatory provisions (to ensure, e.g., interoperability or applicability) and compliance with the Recommendation is achieved when all of these mandatory provisions are met. The words “shal
15、l“ or some other obligatory language such as “must“ and the negative equivalents are used to express requirements. The use of such words does not suggest that compliance with the Recommendation is required of any party. INTELLECTUAL PROPERTY RIGHTSITU draws attention to the possibility that the prac
16、tice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation develo
17、pment process. As of the date of approval of this Recommendation, ITU had not received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementers are cautioned that this may not represent the latest information and are therefo

The keyw
42、ords “is recommended“ indicate a requirement which is recommended but which is not absolutely required. Thus this requirement need not be present to claim conformance. In the body of this Recommendation and its appendices, the words shall, shall not, should, and may sometimes appear, in which case t
43、hey are to be interpreted, respectively, as is required to, is prohibited from, is recommended, and can optionally. The appearance of such phrases or keywords in an appendix or in material explicitly marked as informative are to be interpreted as having no normative intent. 6 End to end cloud resour
44、ce management overview The following clauses provide an overview of the general concepts of end to end cloud computing resource management in a telecommunication rich environment. 4 Rec. ITU-T Y.3520 (09/2015) 6.1 Introduction One significant value of cloud service providers will most likely be the
45、rapid design, development, deployment and management of cloud services. With the adoption of cloud computing service delivery capabilities, multiple service providers will provide more cloud services as composite or mash-up services. Service providers will increasingly have as their objective the ra
46、pid delivery of more customized, composite cloud-based services tailored to various customer scenarios b-FGCC Part 4. In this Recommendation, the term multi-cloud refers to usage scenarios involving the use of various cloud services implemented by more than one cloud service provider (CSP), though t
47、his multiplicity of CSPs may not be visible to the cloud service customer (CSC). This is not to be confused with the multi-platform cloud computing environment, which is a characteristic of cloud service providers that have chosen to offer a variety of programming and runtime execution facilities to
48、 assist in the development and execution of cloud applications. Nor should it be confused with the term “inter-cloud“ which refers to the relationship and interconnection between CSPs and not to the overall end to end system. Cloud applications (also known as cloud workloads) are applications (i.e.,
49、 software programs designed for a specific purpose) that require execution in the cloud service providers data centres in order for cloud services to be instantiated and become available for use by the cloud service users. In other words, a cloud application needs to be executed to make one or more cloud services available. Cloud service providers need to increasingly offer multi-cloud platform solutions to support the above scenarios. Such solutions will ne
