For now, though, I have a small collection of articles and links for your reading pleasure—not as many as I usually include in a Technology Short Take, but better than nothing at all (I hope!). Baptiste Collard has a post on Kubernetes controllers for AWS load balancers. Welcome to Technology Short Take #149! Networking.

I recently came across something that wasn’t immediately intuitive with regard to terminating HTTPS traffic on an AWS Elastic Load Balancer (ELB) when using Kubernetes on AWS. Consider the following YAML, taken directly from the previously-referenced AWS Premium Support article: apiVersion : v1. kind : Service. port : 443.

The real problem is the configuration and management of network policy: stuff like QoS, VLANs, ACLs, NAT, VRFs, firewalls, load balancing, etc. This article was originally posted on blog.scottlowe.org. However, it seems to me that this isn’t the real problem. Please be sure to add vendor affiliations, where applicable.

There should also be built-in flexibility for fluctuations in traffic volumes; this could be done through load balancing to ensure that both standard and peak traffic volumes are adequately supported at all times. This appraisal should pinpoint any enhancements that are necessary to improve the network. Resultant issues.

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). Thanks for reading! This is a handy trick.

Mirantis published an article discussing a framework they built for bare-metal provisioning with OpenStack that allows OpenStack to place workloads onto bare-metal nodes instead of onto a hypervisor.

What about virtualized load balancers? This article was originally posted on blog.scottlowe.org. Think about it: existing protocols like OSPF and BGP (which run in software ) manipulate the forwarding rules in the data plane—does that make them SDN, too? What about NX-OS, JUNOS, or EOS? What about having APIs on switches?
