    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.
