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-Performance 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 re-quirements on the network infrastructures to deliver guaranteed QoS end-to-end connectivity services:

� Mainly bandwidth, latency, jitter, availability and security/confidentiality.

4


Enterprise users of remote IT infrastructuresInterests 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 Project developments� IT infrastructure operations and maintenances burdensome becomes invisible � Efficient Project Execution and results delivery

� Access to shared “High-Performance 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.

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-VPNs (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

« Telecom Service Provider »beyond Connectivity Services delivery

� Telecom Networks and National Research networks have different SLA requirements and consequently connectivity services delivery is different

� Application – Network Interactions

� Cloud Computing Interfaces vs. Network Service Interfaces

� Which interaction level ? Service operations ? Infra. management ? Control ?

� Associate and compose services with heterogeneous QoS parameters

� Which sort of business alliance can be defined between ASP and Telecom Service Providers

� New/extended Data / Information models

� Uniform service discovery, request, selection and composition

� Policy based Service Management for automated functions

� Network abstraction for Cloud computing specifications

� Networks as Services need to be standardized with security constraints

� Virtualized IT Service access require extensions on standard specifications

� Network as services: T. M. Forum, IETF, ITU-T

� Application as services: OGF (NSI, OCCI), OASIS (SCA)

� Virtualized Management Infrastructure with Power saving capabilities
