Focus Group Cloud Computing(June 2010-Dec 2011) Focus Group on Cloud Computing has completed itsstudy into cloud computing’s and has released its TechnicalReport in Seven Parts:1) Introduction to the cloud ecosystem: definitions,taxonomies, use cases and high-level requirements2) Functional requirements and reference architecture3) Requirements and framework architecture of cloudinfrastructure4) Cloud resource management gap analysis5) Cloud security6) Overview of SDOs involved in cloud computing7) Cloud computing benefits from telecommunication andICT is, June 2012,Jamil CHAWKI
Cloud Definitions, Ecosystemand Interoperability10Tunis June 2012,Jamil CHAWKI
ITU-T FG Cloud Definition ITU-T FG Cloud Computing (2011) Cloud Services: Products and solutions that are delivered andconsumed on demand (utilizing IT Resources & capabilities ofPlatform) at any time, through any access network (fixed &mobile) using any connected devices and cloud computingtechnologies. 5 Cloud service categories (SaaS, CaaS, PaaS, IaaS, NaaS) Cloud Computing*: an emerging IT development, deploymentand delivery model, enabling service users to have ubiquitous,convenient and on-demand network access to a shared pool ofconfigurable computing resources (e.g., networks, servers,storage, applications, and services), that can be rapidlyprovisioned and released with minimal management effort orservice-provider interaction. Cloud computing enables cloudservices.* Partially based on NIST cloud definition11Tunis June 2012,Jamil CHAWKI
Cloud EcosystemThree actors playing different roles:1. Cloud Service Provider CSP: XaaS Provider, Inter-Cloud 2. Cloud Service User CSU: Consumer, Enterprise 3. Cloud Service Partner CSN: Application Developer, Integrator Cloud Service PartnerCloud Service PartnerCloud ServicePartnerCloud Service ProviderInter-cloudSaaS CaaS PaaS IaaS NaaSCloud Service UserCloud Service ProviderInter-cloudCloud Service ProviderInter-cloudSaaS CaaS PaaS IaaS NaaSCloud Service UserInternationalTelecommunicationUnionTunis June 2012,Jamil CHAWKI
Cloud interoperability: use cases1. Service cooperation between Cloud providers2. Cloud interoperability between private & public clouds3.

Main Cloud Layers and functions Access layer: Endpoint : controls cloud traffic and improves cloudservice delivery Inter Cloud: addresses delivering any cloud serviceacross two or more CSPs Services layer: Service Orchestration: is the process of deploying andmanaging “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 resources16Tunis June 2012,Jamil CHAWKI
Cloud Security & Privacy17Tunis, June 2012,Jamil CHAWKI
Cloud Security & data Privacy Threats for cloud users: Lack of security Information (data location, backupsystem, disaster recovery ) Data loss and leakage (encryption, authenticationkey ) Loss of Account/Service management ID (Attackphishing, fraud.) Requirements For cloud Services provider Method to trust cloud providers' security level shall beprovided Confidentiality/integrity of data against loss orleakage shall be required Proper account/identity management againstaccount/service hijacking shall be provided. Data Portability, The capability to change Cloud ServiceProvider shall be providedTunis, June 2012,Jamil CHAWKI
