In this episode we continue the conversation about “infrastructure as code.” Last time we chatted about it we talked to Nick Mitchell and Eric Pulvino, two of our consultants, and shared not only what it is but what the problems infrastructure as code is solving for and why you should care. In this latest episode we go a step further. Kernel of Truth hosts Brian O’Sullivan and Pete Lumbis are joined by Anton Karneliuk who talk more about what it is and also discuss how to evolve it, what the challenges are and Anton shares his real-life experiences implemented it at The Hut Group.

Roopa Prabhu and Roopa’s hype man Pete Lumbis join Kernel of Truth host Brian O’Sullivan to discuss why open networking is not just whitebox, it’s so much more. Between the general advantages of this kind of architecture to the benefits of being backed by the Linux kernel and Linux community— open networking is a great option to have not just now but going forward. Learn how this open development community works together to the advantage of everyone, not just networking, and with companies of all sizes, including hyper-scale ones, improving things like the sanitation of code and so much more. As a special bonus you’ll also learn what to eat in the data center. Spoiler: the answer is nothing but Brian might have an opinion otherwise.

But wait, there’s more! If you keep up with our podcast you may have noticed the previous episode where we talk about what open networking was, so why are we chatting about it again? Last time we talked about having open API’s and having the demarcation point between components but in this podcast, we’re extending the conversation out to show how everyone can take advantage of open networking in a wider, practical sense. Guests Rama Darbha and Roopa Prabhu join host Brian to share their thoughts, experiences and expertise on the subject. Listen, enjoy, and feel free to comment away here or on our social media channels if you have any questions or thoughts to add.

Click here for our previous episode.

We had a couple of weeks off but we’re back in action, bringing to you a podcast about what makes up open networking in 2019. We took a different approach than normal this time and have guests both from sales & engineering here to discuss the different things they’re seeing from their respective “worlds” with the hopes of bridging the gap between the two of them for you. Joining host Brian is Andreas la Quiante, calling in from Germany no less, and representing the “sales” side of the conversation. On the engineering side, we have some folks you might recognize from previous podcasts: Roopa Prabhu and David Ahern. With that intro out of the way, now is the time to sit down, relax and listen to their conversation here. We hope you enjoy it!

Host Brian talks again to Nick Mitchell and Eric Pulvino, two of our consultants who’ve not only taken certifications throughout their career but worked on and helped to create our open networking certification. Listen as they discuss the value of them, if any, what works for certifications and what doesn’t, who should be taking certifications and more!

As Brian mentions in the podcast, we have a social game going on for 2019 where you can win some fun prizes. Part of the game includes some flash give-aways of free CCONP certification exam registration and more!  Head over to our EPIC Year Game page to learn more or follow us on Twitter, LinkedIn, and Facebook.
