FIA Athens Cloud Federations and SDN/NFV: the highways towards improved QoE, Cost and Energy Efficiency Working Session of FIA Athens 2014 Athens, March 19,

FIA Athens Organizers George D. Stamoulis Athens University of Economics and Business (AUEB) FP7 SmartenIT  Professor, Network Economics and Services Group Roman Łapacz Poznan Supercomputing and Networking Center (PSNC) FELIX, FP7 SmartenIT, GN3Plus  Network Specialist Alexander Willner Technische Universität Berlin (TUB) FP7 Fed4FIRE, FI-PPP XIFI  Future Internet Testbed Group Lead

FIA Athens Objectives  This session aims at setting the stage for Cloud Federation and for Software Defined Networking (SDN) and Network Function Virtualization (NFV) paradigms as its enablers

FIA Athens Cloud Federations  Addressed by several projects:  …  CONTRAIL  OPTIMIS  RESERVOIR  …  FED4FIRE  FELIX  FI-PPP XIFI  SmartenIT  …

FIA Athens Some important topics  What are the expected benefits of cloud federation for cloud operators, OTTs and users?  What is their impact on energy efficiency?  To what extent and how can SDN/NFV bring such benefits?  How can SDN enable or facilitate the interactions among the clouds participating in a cloud federation?  How does SDN/NFV deal with inter-domain service provision? What issues arise with respect to distribution of information among the players, trust etc.  What is the status and role of relevant standardization activities?

FIA Athens Questions

FIA Athens Question 1 What are the benefits of cloud federation for cloud operators, OTTs, ISPs and users? Do they outweigh the associated technical and other overheads?

FIA Athens Question 2 To what extent and how can SDN/NFV bring these benefits?

FIA Athens Question 3 Does SDN/NFV enable the provision of services seamlessly over a cloud federation incorporating heterogeneous services from different operators? What inter-domain issues arise?

FIA Athens Question 4 What is the impact of SDN/NFV-enabled cloud federations to ISPs? How will their traffic management be affected? What opportunities arise?

FIA Athens Question 5 What standardization activities are currently in progress, and what are their topics of highest interest?

FIA Athens Question 7 Which solutions and standards are already in place that can be used to build and support cloud federations? What is missing in terms of protocols, mechanisms, business rules and SLAs etc. to deploy cloud federations?

FIA Athens Question 8 What are the possible technological alternatives to develop and support cost- and energy-efficient and QoE-aware cloud federations except SDN and NFV?

FIA Athens Question 9 Which are some promising use cases for cloud federations? Which are key factors for success?
