A while ago (eons before AWS introduced Gateway Load Balancer) I discussed the intricacies of AWS and Azure networking with a very smart engineer working for a security appliance vendor, and he said something along the lines of “it shows these things were designed by software developers – they have no idea how networks should work.”
In reality, at least some aspects of public cloud networking come closer to the original ideas of how IP and data-link layers should fit together than today’s flat earth theories, so he probably wanted to say “they make it so hard for me to insert my virtual appliance into their network.”

Tom Hollingsworth wrote another must-read blog post in which he explained what one should do before asking for help:
If someone comes to me and says, “I tried this and it failed and I got this message. I looked it up and the response didn’t make sense. Can you tell me why that is?” I rejoice. That person has done the legwork and narrowed the question down to the key piece they need to know.
In other words (again his), do your homework first and then ask relevant questions.

SONiC is a network OS that can run on a variety of whitebox switches. Originally developed by Microsoft, SONiC is now an open-source project with distributions that target hyperscale and enterprise environments. Today's Heavy Networking is a deep dive into SONiC with Dave Maltz, a Technical Fellow at Microsoft who has been closely involved with SONiC's development. While Microsoft is a SONiC backer, this is an unsponsored episode.

Benchmark tests measure a repeatable set of quantifiable results that serve as a point of reference against which products and services can be compared. Since 2018, Alexis Ducastel, a Kubernetes CKA/CKAD and the founder of InfraBuilder, has been running independent benchmark tests of Kubernetes network plugins (CNI) over a 10Gbit/s network.
The latest benchmark in this periodic series of tests was published in September, and was based on CNI versions that were up-to-date as of August 2020. Only CNIs that can be set up with a single yaml file were tested and compared, and included the following:
We are thrilled to report that among all of the CNI’s tested, Calico was the clear winner, excelling in nearly every category and delivering superlative results which are summarized in the chart below. In fact, Calico is the CNI of choice in the primary use cases presented by the author in the report’s summary.

The exceptional performance of Calico encryption was described as having the “real wow effect” among all of Continue reading
Today's Tech Bytes dives into Pluribus Networks’ Linux-based Netvisor ONE OS for white box switches. We also discuss Pluribus’ Adaptive Cloud Fabric, a distributed, controllerless SDN solution for deploying and automating data center fabrics that promises simpler operations and a lower TCO. Our guest is Alessandro Barbieri, VP of Product Management.
