When Snam, an Italian gas company, needed to update its data centers why did it choose Cisco quipment—specifically Nexus switches—to do the job? Because the Nexus switches were the only platform to offer Overlay Transport Virtualization (OTV), which allowed virtual machines to be transferred without interrupting services.

No, I’m not talking about schematics for the Hyperloop (although I’m pretty excited about flying through California in a suction pipe). I’m talking about an even more important network in today’s digitized world: the WAN.
Recent trends such as bring-your-own-device, mobility, and cloud computing have led to a surge in the number and types of devices connecting to the network. With these challenges, how can an enterprise manage demand for WAN bandwidth and fast, secure connectivity with a flat or decreasing operational budget? Read More »

The SD-WAN Bill of Rights talks about your right to never visit a branch office again. Depending on the size of your organization, budget, and operational preference etc there are various ways to exercise this right:
Option 1: Leave it to someone else
Last month, Verizon announced a new SD-WAN service that includes Cisco Intelligent WAN as a managed service offering. For customers, this means you get the best of both worlds.

Yesterday was “Back to the Future Day.” Michael J. Fox had a glimpse into his futuristic world. What if you too had the same capability? Imagine this: you’re an astronaut on a time travel space mission. You come upon a futuristic world years from today, and this is what you see.
A vortex of insurmountable force is sucking you and the surrounding environment into the abyss, yet you’re still attached to the present. You still have control.

Armed with this vision, what would you do if today, October 22, 2015, is your “Back to the Future” day?
This is a continuation of a previous post by Hugo Vliegen, Digital Vortex, Part I: How Not to Be the 40% That Will Fail. (Re-read that post here). In this blog (part II), I will share four key tenets of a digital business network, a.k.a recommendations for the hypothetical NeedToChange company scenario (as referenced in part I).
