Cisco CEO Chuck Robbins: Get ready for the network’s next act

Cisco’s annual user event, Cisco Live, is being held in Orlando, Florida, this week. While Orlando is home to DisneyWorld, Universal Studios and other places where fantasies come true, the one thing that isn’t make-believe is the turnaround of Cisco since Chuck Robbins took over as CEO. When the baton was passed to Robbins in August of 2015, Cisco’s stock was trading at about $25/share and had been moving sideways for years. Today, it’s trading at about $45/share and at a 17-year high, and the turnaround is well underway.Cisco goes back to the network How did Robbins get Cisco’s mojo’s back in such a short period of time? The answer lies in its roots and a refocus on the network. In fact, when Robbins took over as CEO, I wrote a post outlining some priorities for him as he stepped into the role. My first point was to approach IT through the lens of the network.

What Is Intent-Based Networking?

This blog post was initially sent to the subscribers of my SDN and Network Automation mailing list. Subscribe here.

Whenever someone mentions intent-based networking I try to figure out what exactly they’re talking about. Not surprisingly, I get a different answer every single time. Confused by all that, I tried to find a good definition, but all I could find was vendor marketing along the lines of “Intent-based networking captures and translates business intent so that it can be applied across the network,” or industry press articles regurgitating vendor white papers.

IDG Contributor Network: Is the IT help desk model broken?

There’s no doubt about it – today’s workers have fully embraced the trend toward remote working. In fact, according to last year’s Gallup “State of the American Workplace” survey, roughly 43 percent of employees report they have worked remotely.  It would seem that the genie is out of the bottle, and it’s not likely to go back in without a fight.This mass migration off premises changes the dynamic between users and IT help desk teams. An operator can no longer run down the hall to ask a user “Can you show me what the problem is with your computer?” More importantly, without having total visibility in the cloud, the operator may be completely unable to ‘see’ any problems that users are experiencing as they work remotely.To read this article in full, please click here
