Class is in session
As I start to explore more and more information about Software-Defined Networking and Programmability in the Nexus portfolio, I’ve been fortunate that there have been a lot of people helping me learn along the way. I thought I’d share some of these as it gave me a bit more insight into some of the more holistic perspectives that I’ve been trying to get my head wrapped around lately.
I’m still starting off at a rather high level, though I’m spending more and more time getting deeper into the tech. Every once in a while, though, I need to look up and make sure that I’m swimming in the right direction. It’s really easy to get mired in the details and forget the bigger picture. Read More »

Over the past year, we saw the idea of software-defined networking (SDN) become an integral part of IT conversations globally. As this technology evolves, the term “network programmability” can be used to capture the idea of opening up the network.
The Cisco Global Cloud Index predicts that two-thirds of all workloads will be processed in the cloud by 2017, and more than two-thirds of all data center traffic will come from the cloud. Companies building enterprise private clouds, public clouds and hybrid clouds will need qualified talent to optimize their cloud deployments for maximum efficiency.

The industry has been buzzing over the past years around Next Generation of Software Defined and Application Centric networks. If you missed that, it means that you were probably on planet …Zircon (?).
In his recent blog, Colin Lynch @UCSguru and Cisco Champion talks about the skills that network engineers will need in order to design, support and deploy these new networks.
Colin designs and deploys large data centers for a Gold Partner in the UK, and is CCIE#7064 as well as holding certifications in VMware, EMC and NetApp. His Blog is http://ucsguru.com which covers all Datacenter topics but focuses on Cisco UCS. Recently Colin participated to a lively Cisco Champion podcast with Insieme/Cisco Joe Onisick @jonisick on ACI and Nexus 9000.
When recognizing that the traditional networks will not go away overnight , giving ample room for people with the current skill sets, Colin explains what he sees happening, and the course of actions he already took . “I’m certainly no programmer, but I see having basic programming competency as the next skill required to remain in that band of “High Demand” networking professionals.” A reality that many other network engineers start to embrace
A reality that Cisco CTO Padmasree Warrior @padmasree emphasized at a recent NPR broadcast for the Commonwealth Club of California, as she highlighted the importance for the new generation of professionals to learn a programming language . Listen to Padmasree’s speech on “The Business of Innovation : Today and Tomorrow”
Without necessary being amongst those who tend to think “that not being able to code could well be the next definition of literacy” as Colin questions in his blog , more and more network engineers seems to take this steps , including Bill Carter @billyc5022 , who shared also his new skill sets in a recent blog Cisco is bringing together networking and programming .
To better understand Colin’s point of view and discover what are his first steps to be ready for this new breed of networks, read his blog The “Next Gen” Network Engineer” . Tell us what are your first steps , if any.

Most of us have seen the incredible progress and subsequent challenges in the arena of higher education, and there’s no doubt it’s been a big topic of discussion amongst the Cisco Education Team. So, we are excited to announce an upcoming blog series that will highlight some of the key trends, challenges and innovations we are seeing in higher education.
For the next few months, we will host a Thursday blog series focused on the changes in higher education. Starting next Thursday, our own Renee Patton will kick it off by highlighting many of the current trends and challenges. After that, stay tuned each Thursday as we feature blogs covering everything from research universities and online learning models to data sovereignty and analytics. Read More »

One of the great challenges of SDN – that many in my view underplay – is the change in paradigm from having a vendor deliver your network (hardware + software), to having (potentially) an ecosystem deliver your network – and this ecosystem may require you to develop software to perform network tasks or to integrate various SDN components together. This was recognized quite astutely by consultant Jim Metzler, which I discussed in one of my earlier blogs. “Applications can dynamically request services from the network” is what the SDN evangelists will tell you. Jim astutely asked “How exactly do they do that?”. Well ….. the true answer is that either (i) you need to buy [new] apps that do this off the shelf, as it were, or [more likely today] (ii) you need to modify your apps or develop new apps to do this.
Coding – the New Networking?
So are you ready for procuring apps and/or developing software in your network design team now? Don’t worry if you say “no”. Let me first tell you a few customer reactions to this topic, and then let me update you on Cisco Services can help you develop new SDN apps that solve your specific network challenges.
