Networking. Here’s a quick look at using Envoy as a load balancer in Kubernetes. Back in April of this year, Patrick Ogenstad announced Netrasp , a Go package for writing network automation tooling in Go. This is a thorny topic full of design considerations, and this AWS article discusses a few of them.

Networking. I never found the root cause, but we did find a workaround; however, along the way, someone shared this article with me. This is an interesting deep dive into Intel’s “Ice Lake” Xeon SP architecture. A bunch of home Wi-Fi routers are suspectible to attack; see this article for more details.
