5.1.3 GICTF

Global Inter-Cloud Technology Forum (GICTF) aims to promote standardization of network protocols and the
interfaces through which cloud systems interwork with each other and to enable the provision of more
reliable cloud services.

GICTF works on standardization of inter-cloud interoperability, including functional requirements and
interface.

GICTF has developed requirements for inter-cloud computing and inter-cloud interface specification. The
functional requirements of inter-cloud systems have been identified and the inter-cloud interface has been
developed. Three reference points for the interface specified in GICTF's documents are the interface between
inter-cloud service controls, the interface between inter-cloud service controls and data centre operation
systems, and the interface between the inter-cloud service controls and the network operation systems.

5.1.4 IEEE

The Institute of Electrical and Electronics Engineers (IEEE) is a professional association that is dedicated to
advancing technological innovation and excellence.
IEEE works on inter-cloud related aspects of CCI.
The IEEE cloud computing initiative (CCI) is a broad-based collaborative project for the cloud to be introduced
by IEEE. Several products and services that are now being introduced by IEEE CCI, including a website,
conferences, continuing education courses, publications, standards and a platform for testing cloud
computing applications.

Two major cloud computing standards of IEEE CCI are currently in process: [IEEE P2301] Guide for Cloud
Portability and Interoperability Profiles (CPIPs) and [IEEE P2302] Standard for Intercloud Interoperability and
Federation (SIIF). The purpose of CPIP is to advise cloud computing ecosystem participants (cloud vendors,
service providers and users) of standards-based choices in areas such as application interfaces, portability
interfaces, management interfaces, interoperability interfaces, file formats, and operation conversions. CPIP
groups these choices into multiple logical profiles, which are organized to address different cloud
personalities.
SIIF defines topology, functions and governance for cloud-to-cloud interoperability and federation.
Topological elements include clouds, roots, exchanges (which mediate governance between clouds) and
gateways (which mediate data exchange between clouds). Functional elements include name spaces,
presence, messaging, resource ontologies (including standardized units of measurement), and trust
