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.
