Framework and requirements for cloud computing 1

• ITU-T Y.3513: This Recommendation provides the functional requirements and use cases of
Infrastructure as a Service (IaaS), one of the representative cloud service categories. This
Recommendation covers the following:
– general description of IaaS;
– functional requirements of IaaS;
– typical IaaS use cases.

• ITU-T Y.3515: This Recommendation specifies NaaS functional architecture, including
functionalities, functional components as well as reference points and procedures, based on the
functional requirements specified in [ITU-T Y.3512]. The scope of this Recommendation consists of:
– overview of NaaS functional architecture;
– functionalities of NaaS;

– functional components of NaaS;
– reference points between functional components of NaaS;
– procedures for typical NaaS use cases.

• ITU-T Y.3516: This Recommendation 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.

• ITU-T Y.3519: This Recommendation provides an overview of the big data as a service (BDaaS)
functional architecture and defines the BDaaS functional architecture and its cross-cutting aspects
by specifying the functional components for the support of BDaaS.
URI: https://www.itu.int/ITU-T/workprog/wp_item.aspx?isn=13627
• ITU-T Y.dsf-arch: This Recommendation describes the functional architecture for data storage
federation (DSF). The DSF functions based on DSF logical components identified in Y.35XX (ex Y.dsf-
reqts) are introduced. The DSF functional architecture, including DSF functions and DSF functional
components, is specified. This Recommendation also provides the relationship between the DSF
functional architecture and the cloud computing reference architecture.
