Networking. Via Kirk Byers (who is himself a fantastic resource), I read a couple of articles on network automation that I think readers may find helpful. First up is a treatise from Mircea Ulinic on whether network automation is needed. I first ran into Forward Networks a few years ago at Fall ONUG in New York.

Networking. At DevOps Networking Forum 2016, I had the opportunity to share a presentation on some Linux networking options. Here’s another topic that came up at the recent DevOps Networking Forum: Spotify’s SDN Internet Router (SIR). Here’s some information on Nuage Networks’ experimental Docker Network plugin.

Networking. Lindsay Hill walks through using Telegraf, InfluxDB, and Grafana to monitor network statistics. Via Ivan Pepelnjak, I found this article by Diane Patton at Cumulus Networks talking about container network designs. When you’re operating at the scale at which Netflix operates, this is no trivial feat.

It’s time to evolve beyond the UNIX operating system. So while I was editing this podcast on self-healing operating systems, I was reminded of an article that I never finished for Fobes.com. It’s a radical rethinking of how we even view our current choices of UNIX-derived operating systems.

Networking. I enjoyed Dave McCrory’s series on the future of the network (see part 1 , part 2 , part 3 , and part 4 —part 5 hadn’t gone live yet when I published this). Michael Kashin has a handy little tool that functions like ssh-copy-id on servers, but for network devices (leveraging Netmiko).

Networking. Netmiko, if you haven’t heard, is a fantastic Python library that’s really useful when writing Python-based network automation scripts. First up, there’s a great article on using IPVLAN with Docker and Cumulus Linux (with a tie back to sFlow, naturally!). Operating Systems/Applications.
