2 Business models towards «Cloud Computing Services delivery» Enterprises want to lower their IT infrastructure costs and focus on their business projects IT resources externalization/outsourcing ~ 40 % annual growth of Internet traffic generated by datacenters. Visualization and image/video post-production High-erformance Computing access for R&D Industrial Applications: e.g. simulated design, pharmacy Data storage management: streaming, back-up Remote access to Datacenters services delivery imposes strong requirements on the network infrastructures to deliver guaranteed QoS end-to-end connectivity services: Mainly bandwidth, latency, jitter, availability and security/confidentiality. 3 Enterprise users of remote IT infrastructures Interests of accessing IT services from the Cloud Catalyst for Virtualized IT Services from Telecom Service providers is: Maximize usages of IT infrastructures for the Business Users IT infrastructure fixed costs (TCO) can be significantly reduced Virtual Organization practices and service on-demand Virtual Labs / Virtual Enterprises based on the «pay-as-you-use» The infrastructure is scaled dynamically according to organization needs Collaboration under short time constraints for Research/Business roject developments IT infrastructure operations and maintenances burdensome becomes invisible Efficient roject Execution and results delivery Access to shared High-erformance Computing" services Based on Service oriented Architecture: e.g. OGSA/OGF, SCA/OASIS. Response to new regulations: Network management/control solutions supporting IT Service requests are needed for emerging virtualized infrastructure as services market. 4 2

3 Requirements on Network Infrastructures for «Cloud Computing Services delivery» Automated infrastructure management and operations supporting external network service interface to provision connectivity services Services are specified from SLA (QoS, SEC) Connectivity requests are derived Network Services are automatically selected Lx-VNs (x = 1,2,3) Service and Network management interactions with Explicit Resource Selection Network Services can be provisioned with Instant or Scheduled resource reservation SRV = Scheduling and Reconfiguration of connectivity for Virtualized services delivery 5 Towards Virtualized Infrastructures and «Generalized Service roviders» High Energy hysic ers Bio-informatics Scientists Client SLA Service Cliquez pour resentation Integration & modifier le style du titre Service Storefront Generalized Service rovider (GS) Software Application Services Services I.T.
