    Ivy Insights

    The Packet Pushers - Fat Pipe podcast is my favorite and main podcast at the moment. It covers a wide range of topics in Networking, allowing me to stay up to date with all the latest innovations and developments. I have been listening since 2011 and have witnessed the show not only maintain its high standard but also improve over time. Greg and Ethan have done an amazing job in maintaining their independence and providing valuable insights in their own unique way.

    One of the best aspects of this podcast is that it provides a wealth of technical knowledge without getting bogged down by sales and marketing hype. The hosts keep the discussions focused on the details that most network content tends to gloss over. This makes it an excellent resource for networking professionals who are looking for in-depth technical information.

    Another great aspect of this podcast is the variety of topics covered. From traditional route/switch and wireless to data center technologies, there is something for everyone in the networking field. The hosts bring on experts from various backgrounds, providing different perspectives and insights into these topics. This diversity keeps the content fresh and interesting.

    As for drawbacks, one could argue that the technical nature of this podcast may not be suitable for beginners or those with limited networking knowledge. However, I believe that even for less experienced individuals, listening to this podcast can be a valuable learning experience as long as they are willing to put in some effort to understand the technical concepts being discussed.

    In conclusion, The Packet Pushers - Fat Pipe podcast is an excellent resource for anyone working in networking or interested in staying up to date with the latest developments in this field. With its technical depth, independence, and variety of topics covered, it offers a unique listening experience that is hard to find elsewhere. Bravo to Ethan, Greg, and Tony for creating such an invaluable wealth of knowledge!
