ITU-T FG Cloud Definition
ITU-T FG Cloud Computing (2011)
Cloud Services: Products and solutions that are delivered and
consumed on demand (utilizing IT Resources & capabilities of
Platform) at any time, through any access network (fixed &
mobile) using any connected devices and cloud computing
technologies.
5 Cloud service categories (SaaS, CaaS, PaaS, IaaS, NaaS)
Cloud Computing*: an emerging IT development, deployment
and delivery model, enabling service users to have ubiquitous,
convenient and on-demand network access to a shared pool of
services. * Partially based on NIST cloud definition

Main Cloud Layers and functions Access layer:
Endpoint : controls cloud traffic and improves cloud service delivery
Inter Cloud: addresses delivering any cloud service across two or more CSPs
Services layer:
Service Orchestration: is the process of deploying and managing “Cloud Services“
Cloud ecosystem: definitions, taxonomies, use cases & high level requirements
1. Cloud Computing related definitions & taxonomies: 5 Cloud service categories (SaaS, CaaS, PaaS, IaaS, NaaS) with 2 new categories for Communication (real time) and network (transport & inter-cloud)
2. Cloud ecosystem actors (provider, partner & user) and roles
3. Inter-cloud Scenarios : Peering, Federation & Service Broker
4. Telecommunication centric use cases: Service Delivery Platform, Desktop as a Service, Call center, Cloud migration and portability, Inter-cloud (SLA, performance, availability...)
5. High level requirements:
For cloud infrastructure accessibility, massive data processing, portability, responsiveness…
For cloud services: SLA support, management, Inter-cloud
