Cloud: the IT Revolution• Applications

• Development environments

• Infrastructures

• are moving to the Cloud and are delivered as a service


Forecast: from about $41 billion in 2011 to $241 billion in 2020

– Develop techniques to move from today’sto future networks

• Technical objectives– Network of Information (NetInf): application

support via an information-centric paradigm– Open Connectivity Services (OConS): signalling and control interfaces for

heterogeneous media technologies– Cloud Networking (CloNe): integration of networking with cloud computing via

NW virtualization and self-management– Plus socio-economics, standardisation, network migration, business models, ...

Where there is consensus

� Complexity slows down the adoption and generalizationof Cloud approach.

� Hetereogenity limits portability, reliability of Cloudapplications and interoperability of Cloud services.

Where there is NO consensus


� Hardware, Hypervisors, Virtual Network technologies, Cloud software, Cloud Infrastructures APIs & services

Where there is NO consensus

Need for consensus at the right abstraction level

Model-based approach for Virtual Infrastructure

� Separate the specification of

� Functionality and Capacity

� from the specification of

� the implementation of that functionality

� the provisioning of that capacity� the provisioning of that capacity

� on a particular technology plateform

� “Design once, provision and run it on any platform”
