MUST READ: Lessons from load balancers and multicast

Justin Pietsch published another must-read article, this time dealing with operational complexity of load balancers and IP multicast. Here are just a few choice quotes to get you started:

  • A critical lesson I learned is that running out of capacity is the worst thing you can do in networking
  • You can prevent a lot of problems if you can deep dive into an architecture and understand it’s tradeoffs and limitations
  • Magic infrastructure is often extremely hard to troubleshoot and debug

You might find what he learned useful the next time you’re facing a unicorn-colored slide deck from your favorite software-defined or intent-based vendor ;))
