  If you are following the industry debates around Software Defined Networking (SDN), and are wondering “What really is SDN?”, “How the concepts of network virtualization and network programmability relate...

While I’ve been writing about Cisco Domain TenSM, I’ve been watching the SDN debate evolve in our industry, and I have to say, I’ve had my concerns.  Don’t get me wrong – I personally see SDN as an important and very much required evolution (and note: ‘evolution’ – not ‘revolution’) of the networking industry.  Being […]

Here are some highlights.   Rusty Buzhardt (Cisco), Jason Nash (Varrow), Elijah Stukenborg (Chiquita) Really enjoyed an inspirational keynote by VCE President Frank Hauck and the opportunity to […]

Last week at the RSA Conference in San Francisco, I had the pleasure of speaking to thousands of security professionals about the opportunities and risks associated with using Software Defined Networking (SDN) for security, which will be the underlying fabric of our next generation data centers and networks. SDN-enabled security will provide a better way […]

In this week’s episode of Engineers Unplugged, Brian Gracely (@bgracely) of Virtustream takes on the challenge of explaining the industry’s top buzzword, Software Defined Networking, using doughnuts. Seeing is believing: Welcome to Engineers Unplugged, where technologists talk to each other the way they know best, with a whiteboard. The rules are simple: Episodes will publish […]
