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

configurable computing resources (e.g., networks, servers,

storage, applications, and services), that can be rapidly

provisioned and released with minimal management effort or

service-provider interaction. Cloud computing enables cloud

services. * Partially based on NIST cloud definition

Cloud interoperability 1. Service cooperation between Cloud providers

2. Cloud interoperability between private & public clouds

3. Cloud Service portability between cloud providers

4. Mutual backup and recovery from a disaster

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 Services: provides instances (and composition) of CaaS, SaaS, PaaS, IaaS & NaaS

Resources & Network Layer:

Resource orchestration

Pooling Virtualization: compute, storage, network, software & platform assets

Physical resources

5 Cloud Security & Privacy

17



Cloud Security & data Privacy Threats for cloud users:

Lack of security Information (data location, backup system, disaster recovery…)

Data loss and leakage (encryption, authentication key…)

Loss of Account/Service management ID (Attack phishing, fraud..)

Requirements For cloud Services provider

Method to trust cloud providers' security level shall be provided

Confidentiality/integrity of data against loss or leakage shall be required

Proper account/identity management against account/service hijacking shall be provided.

Data Portability, The capability to change Cloud Service Provider shall be provided

Thank You



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
