When it comes to IT projects — be they WAN or any other domain — there’s a general rule of thumb that should be applied but often is not: if the solution is more complicated than the problem, then don’t do it. With many customers I’ve talked to about SD-WAN, the solution has indeed been more complicated than the legacy WAN they were running before. Most agree the network is more agile but operationally more difficult to run.

Software-defined WAN (SD-WAN) continues to pick up momentum as organizations look to evolve their networks to meet the demands of digital transformation, Internet of Things (IoT), and other trends. But how does one know that the business is ready to make this shift? An SD-WAN is significantly different than a legacy network and requires new ways of doing things.

The topic of WAN transformation has been a hot topic over the past couple of years. In fact, earlier this year, Mark Haranas, the fine reporter with CRN, recently authored an article declaring that 2016 would be a breakout year for SD-WAN.

Happy New Year to WANSpeak readers! By now, I’m sure many of us have made a start on our annual resolutions. I’m sure Donald Trump has made a resolution to antagonize even more of the country, Michael Dell has likely resolved to make the Dell/EMC merger smooth, and I’m sure Tom Brady has resolved to make sure all his footballs are at least 12.5 PSI.

2016 should be a significant year of change for networking professionals, as the role of the network has changed. Historically, the network was considered the “plumbing” of the organization and was something few CIOs were concerned with. Today, many of the current IT initiatives such as mobility, cloud computing and Internet of Things are network-centric, meaning the network plays a much more important role. Because of this, the network and network managers need to change. This year, network managers should consider the following resolutions.

The year 2015 is almost in the books. That means it’s time to say, “I can’t believe the year is almost over,” and time for many of us in the industry to make some bold predictions as to what we think the future holds. I had intended to write a post with some standalone thoughts on what the coming year will bring, but then I read the recent piece by David Hughes filled with 2016 networking predictions and thought I would weigh in on his prognostications instead.

One of the quotes that Albert Einstein is credited with is: “The definition of insanity is doing the same thing over and over again and expecting different results.” If that is indeed how insanity is defined then there is no part of IT that is more insane than the corporate WAN. I’ll explain why I say that below.

I moderated a workshop on the topic of software defined WANs (SD-WAN) last month and I’m continually baffled that the focus of software-defined networking remains on the hardware for so many individuals. This is clearly a hangover from the early days of SDN when many of the start ups were hammering home the point that hardware is expensive and businesses should move to a software-defined model and cut capital costs.
