Each week, SearchSDN takes to Twitter to see what users, experts, analysts and editors are saying about SDN. By using Storify and searching hashtags, keywords and tweetups, we scour the social media site to see what users have to say about SDN, OpenFlow, network virtualization and more. This week, we looked to Twitter and got an earful from tweeters about the impact of SDN on hardware, the state of SDN and network virtualization.
SDN, the cloud and hardware
As the Cloud Expo continues, we continue to see SDN discussion on Twitter on how SDN is impacting hardware. In his recaps of the event, Tweeter Faisal Hanif documents what he heard regarding cloud and SDN, and how the two technologies are altering the networking industry.
SDN a disruptive technology?
In his tweet, user Paul Gainham predicts SDN will be a major disruptive force in both service provider and enterprise networks, tearing down the siloes in IT.
#SDN will be a major organisational disruptor for SP and ENT IT alike. The days of clear app/storage/network boundaries are nearing an end.— Paul Gainham (@PaulGainham) July 17, 2013
Is SDN equal to network virtualization? Industry heavyweights still say, 'No'
Brent Salisbury, @networkstatic, said on Twitter that equating network virtualization with SDN is a "broke statement." VMWare's Martin Casado, who has openly commented on this issue before, chimed in on the conversation, as did Joe Onisick.
network-virt != SDN is a broke statement.— Brent Salisbury (@networkstatic) July 16, 2013
@networkstatic net-virt == SDN makes as much sense as server-virt == functional programming. It equates a solution to an approach.— martin_casado (@martin_casado) July 16, 2013
@networkstatic or put another way, it's a broken statement because there isn't an equivalency class between the two ;)— martin_casado (@martin_casado) July 16, 2013
The future of network virtualization
This week, the 2013 VMware Academic Research Symposium took place, and William Lam, staff product integration architect at VMWare, took to Twitter to offer insight into the symposium's discussions, especially related to the use of network virtualization. Included in his tweets are interesting tidbits about the role of the virtual switch and the controller cluster as the "heart" of a network virtualization platform.
Network Virtualization extends the benefits of Server Virtualization to the whole DC. Biggest shift in Net in a generation #vmwSymp2013— William Lam (@lamw) July 17, 2013
What's next for Network Virtualization? Federation/Multi-DC, Physical/Virtual Integration, Adv L4-L7 services, SW Forward Perf #vmwSymp2013— William Lam (@lamw) July 17, 2013
The heart of the Network Virtualization Platform is the Controller Cluster which is the brain of the entire system. #vmwSymp2013— William Lam (@lamw) July 17, 2013
Nicira Network Virtualization Platform uses Open vSwitch that can run on multiple Hypervisors #vmwSymp2013— William Lam (@lamw) July 17, 2013
starting point for Network Virtualization is the Virtual Switch. Cool fact, half of all Server Access Ports are already virtual #vmwSymp2013— William Lam (@lamw) July 17, 2013
The solution - Transform the Network with Virtualization through programmatic provisioning & place workload anywhere #vmwSymp2013— William Lam (@lamw) July 17, 2013
