Networking Kevin Jin’s post on the APNIC blog about network automation tools is a great read. He discusses Netmiko, NAPALM, and Nornir in some detail, and provides some guidance around which network automation tool may be right for you. Anton Kuliashov writes about why Palark uses Cilium for Kubernetes networking.

Networking. Isovalent, the folks behind Cilium, recently unveiled the Network Policy Editor, a graphical way of editing Kubernetes Network Policies. Ivan Pepelnjak, the font of all networking knowledge, has been discussing cloud networking in some detail for a good while now. Want/need to better understand IPv6?

Networking. This article contains some good information on IPv6 for those who are just starting to get more familiar with it, although toward the end it turns into a bit of an advertisement. Want to understand kube-proxy , a key part of Kubernetes networking, a bit better? Operating Systems/Applications.

Networking. Vincent Bernat has a really in-depth article on IPv4 route lookup on Linux (and one on IPv6 route lookup as well). Ivan Pepelnjak has a great article that tries to get to the kernel of truth in the middle of the intent-based networking hype. The company is VirTool Networks (catchy, eh?), RIP Solaris.

Networking. Michael Kashin has a great article on how Open Virtual Network (OVN, part of the Open vSwitch project) implements virtual networks in OpenStack. In a bit of an older post from late summer 2016, Matt Oswalt outlines why network engineers should care about the network software supply chain. Good advice.

Networking. Michael Ryom has a nice (but short) article on using Log Insight along with a NetFlow proxy to help provide more detailed visibility into traffic flows between VMs on NSX logical networks. BGP seems to be emerging as an early front-runner for a standards-based control plane for software networking. Servers/Hardware.

It is the ultimate incrementally scalable system; simply by adding resources it can handle scaling needs in storage and performance dimensions. It also needs to handle every possible failure of storage devices, of servers, networks and operating systems, all while continuing to serve hundreds of thousands of customers.
