Hedge 172: Roundtable! SONiC, Open Source, and Complexity

It’s roundtable time at the Hedge! Eyvonne Sharp, Tom Ammon, and I start the conversation talking about the SONiC open source NOS, and then wander into using open source, build versus buy, and finally complexity in design and deployment.

Thanks for listening–if you have an idea for a Hedge episode, would like to be a guest, or know someone you think would be a good guest, let one us know!
