For this new episode of the podcast with Cisco Champion, we are fortunate to have a great technical (and casual) dialog between two active members of the data center and cloud social media sphere.
Colin Lynch (@UCSguru) based in London is a subject matter expert for Cisco UCS, Integrated Systems, Converged Infrastructure and writes also on SDN . Colin has an independant blog at UCSguru.com He was nominated ComputaCenter Consultant of the Year in 2013 .
Colin talked with Joe Onisick (@jonisick) who works for Insieme Networks, now part of Cisco. Joe writes an independant blog at DefineTheCloud.com. He talked about ACI in multiple videos and podcasts.
After attending Cisco Live Europe in Milan, Colin was at VMware PEX to have an in-depth analysis of NSX , and wanted to “challenge ” Joe on several points, which makes this conversation even more lively !
I found this dialog extremely rich, as both participants were willing to address difficult and controversial aspects of the Data Center architecture today and tomorrow, for instance around layer 2 and layer 3, network programmability and management, or the future of networking certification ! You will also better understand, why Cisco is heavily investing in ACI solutions, when at the same type keeps developing other paths .
A very exciting 40 mn conversation between two great subject matter experts, really passionate by this topic, spiced with additional questions from other Cisco Champions and…humor.
Listen now to our guests and enjoy the show hosted by @commsninja.
I also encourage you to read this very didactic explanation from Tom Edsall, Cisco Fellow and CTO of Insieme Networks, in this new blog from Shashi Kiran
ACI Design Principles : The Role of SDN Overlays in Application Centric Deployement . Shashi will publish the second part tomorrow .
As a reminder, Cisco Champion is a community of technical professionals who are passionate about sharing their knowledge and expertise. They are ready to offer their time to help others to learn about Cisco and connect with Cisco in unique way
For Data Center and Cloud , we have now more than 40 members, who have been nominated by peers for one year . We invite them to give their opinion on market trends, Cisco solutions and products . We encourage also them to participate to our Cisco Live events , webcasts, podcasts , Google + HOA , blogs and tweet to share their experience and wisdom.

ONS summit 2014 starts Monday March 3, and for me it is my first time here. It hardly feels that way. For us in Cisco ACI (Application Centric Infrastructure) team, it is busy last few days as we are putting final touches to showcase our exciting ACI solutions, demos and presentations to customers at this premier SDN event. Early in 2014, Cisco ACI expert Mike Cohen has made insightful predictions on what awaits SDN in 2014 – Read his Blog
Mike zeroes in on key Data Center use cases for SDN, starting with Application Deployment Acceleration securely and at scale. No one can disagree with this. L4-L7 services chaining for physical and virtual devices is another killer use-case Mike enlightens the reader with, and at the ONS Solutions Expo this year, we are showing exciting demos to illustrate service automation using dynamic L4-L7 service chaining. Do not miss out our demos at Cisco Booth 302. We are also showing demos focused on Open Stack integration with ACI, another area of growing interest.
I strongly recommend you to attend Mike’s Theater presentation titled, “Role of Policy in SDN” on March 5, 12.40 PM. Learn all the benefits and value-props that a declarative policy based ACI approach brings to network operations that is today crippled by imperative management, lack of scalability and flexibility. You will be excited to discover how our Cisco ACI team is working with Open Stack, Open Daylight initiatives and driving an open eco-system. Mike will also touch on how ACI helps bring visibility across both physical and virtual infrastructures, and how today’s SDN network overlay problems can be overcome. Shashi Kiran posted a fantastic blog on SDN overlays in ACI deployments, last week, and it makes compelling read in the context of Mike’s session.
We wish you a great ONS summit this year and look forward to seeing you at Cisco Booth 302

The proliferation of different types of device interfaces places a significant burden on application developers and equipment providers alike. One of the reasons for the rise of Software Defined Networking (SDN) is its promise to simplify management by providing a single point through which the entire network can be managed and administered. This raises the question whether this promise extends towards dramatic simplification of the device interface landscape as well, specifically, whether SDN can put an end to device interface proliferation and in the future a single management and control interface may be all that is required. Unfortunately, it turns out that this particular hope is unsubstantiated. Here is why.
The Promised SDN Land of Interface Simplification
Much has been made of the need to align the various interfaces through which networking devices can be managed and controlled. It has been difficult enough to just keep SNMP implementations consistent. Throw CLI, syslog, and Web Services into the mix, and the task becomes daunting indeed. One reason why different interfaces have to be supported has to do with customer preferences, of course. Chef is the new paradigm to support? Sure, we’ll add that. ReST is becoming en-vogue? We’ll support that too.
In the middle of all this, along comes SDN. “Don’t bother with individual devices and their legacy interfaces” is the siren call. “Use a controller to orchestrate the network instead” – a single point of control through which the network can be operated and maintained, an enticing value proposition indeed. Early SDN technology such as OpenFlow made a big splash and gained a lot of mind share this way. Rather than messing with the hodgepodge of existing interfaces, a single interface was introduced to control OpenFlow switches. Just support this one interface, or so the message went, and your equipment can join the New World of Software-Defined Networking, leaving the Old World of fragmented interfaces behind, much like early European settlers coming to America hoped for freedom and a better life, leaving behind constantly quarreling fiefdoms and many centuries of historical baggage.

On February 18, Cisco announced the evolution of service provider (SP) networks. It is probably a good idea to step back, just a little, and explain how Cisco sees the challenges ahead and how we intend to continue to provide our mobile service provider customers with the strongest portfolio of solutions in the industry. That’s the reason I am writing this blog post. In it, I hope to share with you some of our learnings from the past year and also, explain a little bit about the rationale for our announcement.
We are virtualizing our entire SP portfolio. The year 2013 is one where the concept of “Network Function Virtualization” (NfV) caught the industry by storm. In NfV, virtualized network functions are software appliances executing on virtual machines delivered in a telco cloud environment. In a nutshell, NfV is attractive to our customers because it allows them to clearly delineate the respective values of software, hardware and professional services for total solution integration. Practices based on data center techniques promise to reduce the cost of operating the network and simplify work processes through the agility we are seeing today in the cloud environment. And none of this evolution will compromise the ability of service providers to deploy multi-vendor solutions though it is fair to state, procurement practices will need to re-align to this brave new world. For example, rather than procure integrated network functions to be assembled into a network, service providers may have to separate out layers Read More »

As I was thinking about how best to advise you on how to “experiment” with SDN technologies, and more specifically why you should run a formal pilot to evaluate SDN technology options (a topic I covered in my previous blog), I was reminded of this “wipeout” picture I took last year at a “freeride” competition – the “Coe Cup“ -- at my local ski mountain, Glencoe Moutain Resort, here in the UK. Let me tell you why!
Why you may want to “pilot” new technology adoption!
