In this podcast we have an in-depth conversation about the different types and levels of innovation in the data center and where we see it going. Spiderman aka Rama Darbha and host Brian O’Sullivan are joined by a new guest to the podcast, VP of Marketing Ami Badani. They share that while innovation in the data center doesn’t appear sexy, outside of network engineers, in reality there has been a huge paradigm shift in the way data centers have built and operated last 3 years. So what does that mean? How is automation involved in this conversation? Listen here to find out.

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.

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!

Infrastructure as code

Our consultants are often the first to hear about trends and issues that customers and the industry as a whole are seeing and dealing with. Recently we’ve found that quite a few were unaware of what “infrastructure as code” is so we thought, let’s demystify it for everyone! Host Brian talks to Nick Mitchell and Eric Pulvino, two of our consultants who have first-hand knowledge about the topic and share not only what it is but what the problems infrastructure as code is solving for and why you should care! As you listen beware, there may be a “dad joke” and an attempt at Buzzword Bingo along the way. Apparently, it can’t be helped when you’re talking about “git.”
