SDN for the Cloud

SDN for the Cloud
Cloud computing is a new paradigm, which touches everything from enterprise data centers, to wide area networks, to massive scale data centers, with millions of servers. Coordi- nating such large systems requires a new way to control the network – setting a target state for each component and driving each to the goal state, so that the network meets global objectives, in a sea of growth and change: customers creating and adapting virtual networks at amazing pace, while new features are rolled out, new data centers are built out and older ones decommissioned. Software Defined Network- ing (SDN) is a key enabling technology, built on principles of delivering direct control and network-wide views. At Microsoft Azure, we pioneered these principles, and built them into the fabric of the Cloud.

I will discuss the SDN journey and my personal journey from WAN to Cloud, covering some of the hard problems that gave birth to the SDN design principles, which thanks to the investments of amazing teams, led to high scale, highly reliable, high performance, and flexible networks. As cloud computing evolves, the journey continues, with amazing innovation in hardware and software. I discuss some new directions and challenges we are tackling at Microsoft Azure, that enables and accelerates further innovation, and close with an Azure SmartNIC demo. You will hear about more of these ideas and see the Azure Cloud Switch demo at the conference. 

Biography of Albert Greenberg
Albert Greenberg is Distinguished Engineer and Director of Development for Microsoft Azure Networking, leading software and hardware development and engineering for Microsoft’s networks, for all Microsoft first and third parties, encompassing physical data center, regional and wide area networking, host networking datapath, virtual networking, virtual appliances, network services, edge networks and services. Within Azure, he founded and led the network virtualization, datapath and physical data center network teams in Azure, as well as other teams in networking and monitoring. He worked in the Networking Research Group at Microsoft Research on the data center networking technologies now widely deployed in Microsoft services and products, such as Virtual Layer-2 (VL2), Virtual Networks (VNets), Load Balancing (Ananta), Data Center TCP (DCTCP). Joined Microsoft from Bell Labs and AT&T Labs Research, where he was an AT&T Fellow and Executive Director, and where he helped build the systems and tools for engineering and managing AT&T’s networks. Albert Greenberg is the recipient of the 2015 IEEE Koji Kobayashi Computers and Communications Award, a ACM Fellow, ACM Sigcomm Award winner, and ACM Test of Time Paper Award winner. He serves on the board and the technical advisory council of the Open Networking Foundation. ___________________________________________________________________________________________________

Towards the extinction of mega data centres? To which extent could cloud be distributed at the network edge?
Cloud computing emerged, a decade or so ago, from underused computing and storage ressources in Internet players mega data centres that were thought to be provided "as a service". As a result of this inception, Cloud is often considered as a synonym for massive data center, which somehow fuels a very centralised vision of (cloud) computing and storage provision. However, we might be at a time in which the pendulum begins to swing back. Indeed, several initiatives are emerging around a vision of more geographically distributed clouds where computing and storage resources are made available at the edge of the network, close to users, in complement or replacement of massive remote data centres. This talk will discuss, through some examples, the evolution of cloud architectures towards more distribution, the signs and stakes of these mutations.

Biography of Thierry Coupaye
Thierry Coupaye is head of research on cloud platforms inside Orange Labs, and Orange Expert on Future Networks. Prior to that, after he completed his PhD in Computer Science in 1996, he had several research and teaching positions at Grenoble University, European Molecular Biology Laboratory (Cambridge, U.K.) and Dassault Systems. Within France Telecom and then Orange, he had several research expert, project manager, project and program director positions in the area of distributed software architectures, autonomic and cloud computing. He is the author of more than 60 refereed articles, has participated in multiple program and organisation committees of conferences in these areas, and is a regular expert for French and European research agencies.

Networking in the Big Data Era
The volume of data being produced today is increasing to astronomical levels; such huge volumes of data are currently known as Big Data. Indeed, the recent introduction of smartphones and tablets, together with the widespread use of social networks, has even turned individuals into active sources of data production. Facebook receives approximately 30 billion uploads every month, implying a daily generation of 10 terabytes (TB) of data, while Twitter generates more than 7 TB of data every single day. Equally important is the information generated by the use of 5 billion mobile phones worldwide. These realms of data must also be processed to transform them into useful information and discover hidden inter-data relationships. Today, we are on the verge of a new era, and advancement will depend crucially on our capacity for effective and efficient communication of such enormous quantities of data.  In consonance, in this talk, I will discuss the major challenges for networking technology in the provisioning of communication in the emerging era of Big Data.

Biography of Nelson Luis Saldanha da Fonseca
Nelson Fonseca obtained his Ph.D degree from the University of Southern California in 1994. He is a Full Professor at the Institute of Computing, State University of Campinas, Brazil. He supervised 50+ graduate Thesis and published 300+ refereed papers on different topics such and multimedia service, traffic management and resource allocation in clouds and virtualized networks. He received the ComSoc Joseph Lo Cicero Award for Exemplary Services to Publications, the Medal of the Chancelor of the University of Pisa, the State University of Campinas Zeferino Vaz award for academic productivity in Computer Science and the Elsevier Computer Network Journal Editor of Year 2001 award. His graduate students received several awards in Latin America Thesis contests. Currently, he is the ComSoc Director for Conference Development and he served as ComSoc Vice President Member Relations, Director of Latin America Region and Director of On-line Services. He is past EiC of the IEEE Communications Surveys and Tutorials and a Senior Editor for the IEEE Communications Magazine. He is on the editorial board of Elsevier Computer Network Journal, Peer-to-Peer Network and Applications, Journal of Internet Services and Applications and Journal of the Brazilian Computer Society. He founded the conferences IEEE LATINCOM, IEEE LATINCLOUD and the series of Multimedia Communications Symposium in IEEE ICC and IEEE Globecom. He also chaired over 10 IEEE conferences.
