Networking Lee Briggs (formerly of Pulumi, now with Tailscale) shows how to use the Tailscale Operator to create “free” Kubernetes load balancers (“free” as in no additional charge above and beyond what it would normally cost to operate a Kubernetes cluster). Think Linux doesn’t have malware?

Xavier Avrillier walks readers through using Antrea (a Kubernetes CNI built on top of Open vSwitch—a topic I’ve touched on a time or two) to provide on-premise load balancing in Kubernetes. Servers/Hardware. Cabling is hardware, right? Ouch— another Azure vulnerability that allows cross-account access.

Speaking of VPCs and subnets, here’s an example of a Terraform module for a VPC with public, private, and internal subnets (similar to the article in the previous bullet). No worries, Calvin Hendryx-Parker has an example of building AWS VPCs with SaltStack formulas. Servers/Hardware. Prefer SaltStack to Terraform?

Examples of SDN/NFV workloads include wireless BTS, CRAN, MME, DSLAM, BRAS, and core routers. A traditional SRF architecture can be replicated with COTS hardware using multi-queue NICs and multi-core/multi-socket CPUs. Workloads are scheduled across these server/linecards using Valiant Load Balancing (VLB).
