Virtual Appliances Going Mainstream In The Data Center

VMware, EMC’s majority-owned virtualization business, has been pushing the software-defined data center for close to two years, but while SDDC still remains more of a concept than a reality, virtual appliances are going mainstream in the data center, according to a new report from Infonetics Research. “Virtual application delivery controller (ADC) revenue is growing fast […]

Your old security model is broken — will SDN save it, or smash it completely?

Sometimes the blindingly obvious is just too big and close to see clearly. The recent report by the BBC that the European Union’s law enforcement agency Europol has warned people not to use public Wi-Fi for online banking and other sensitive data will have instantly sparked from many of us a response along the lines […]

Network Security: The Bad Guys Are (Still) Winning

Now that RSA Conference 2014 and Mobile World Congress 2014 are out of the way, network security can be forgotten about, at least for a week or two until Interop Las Vegas. That’s because when it comes to network security (or security in general), if it isn’t seen to be broken, it tends to be […]

So What Was The Buzz at ONS?

I just attended the 2014 Open Networking Summit (ONS) in Santa Clara, CA.  While there, one observation I made is that there were a lot more exhibiting vendors at the conference this year than there were last year.  The fact that all of those vendors were in attendance raises an obvious question: was there any […]

The SDN Effect — One, Two, or Three?

Two years ago most articles, webinars, and seminars on SDN seemed to focus largely on some of the more technical details, such as the role of OpenFlow.  In the last six months, however, the conversation has changed to where it now often focuses on linking business policy and SDN.  It is difficult to be against […]

Wide Area Networks are the Low Hanging Fruit of SDNs

Software Defined Networks (SDNs) have obviously been a hot topic on this site and many others for the past few years.  Despite the media hype, SDNs remain somewhat of an enigma for many enterprise network mangers.  The concepts of automation, programmability, and centralized control make sense to most network professionals I have talked to.  However, […]

Don’t Let A Data Center Outage Leave You Out In The Cold

Welcome to the winter of my discontent: outside the wind is moaning and shrieking up a storm, snow buries the landscape, temperatures keep plummeting and groundhogs are turning up frozen stiff as boards. So it seemed appropriate to consider disaster recovery and business continuity (DR/BC). Today’s data centers — yours or your service provider’s — […]

SDN: Necessity, Infatuation, Dated, Or Will Never Happen?

Santa Clara in early February will be home to the inaugural OpenDaylight Summit, the conference intended to advance the community-led and industry-supported open source Software-Defined Networking (SDN) and Network Functions Virtualization (NFV) platform. “Getting together to learn from each other and meet face-to-face is an important component of accelerating adoption of SDN and NFV,” said […]

SDN Deployment: Mass-Market Ready Or Still Cutting Edge?

Are you getting ready to deploy SDN this year?  The genesis of that question is the fact that SDN has been one of the hottest topics in IT for the last eighteen months, and hundreds of articles, reports, and blogs have been written about it.  After all that time and all those documents, it seems […]

Networking in the Year of the Horse

Happy New Year to everyone.  The Chinese New Year on 31st January brings in the Year of the Horse — is this analogous with what we can expect to happen in the networking world through the rest of the year? Luckily, the horse world is varied, so we can probably draw enough comparisons to come […]
