In this post, I’m going to provide a brief introduction to working with Linux containers via LXC. Both full machine virtualization and containers have their advantages and disadvantages. I’m using Ubuntu 12.04.3 The default is “veth”; this uses virtual Ethernet pairs. (If

Redpill Linpro talks to readers about their new routers running Cumulus Linux. I’m pretty sure I’d heard of this utility before, but somehow it fell off my radar/map. I recently found this page , and thought it was a great idea—trying to bring improved security to the masses. That’s cool.

Russell Bryant has a post on Open Virtual Network (OVN) , a project within the Open vSwitch (OVS) community. I like this article on using Couchbase on AWS from Kubernetes because it addresses an often-overlooked (in my opinion) aspect of containerized/microservices architectures: they still need to communicate to external services.

In this post, I’m going to build on my earlier introduction to CoreOS by taking a slightly more detailed look at etcd. etcd is a distributed key-value store (more on that in a moment) and is one of the key technologies that I feel distinguishes CoreOS from other Linux distributions.

Craig Matsumoto of SDN Central helps highlight a recent (and fairly significant) development in networking protocols—the submission of the Generic Network Virtualization Encapsulation (Geneve) proposal to the IETF. This next round of hardware offloads seems targeted at network virtualization and related technologies.

Given my previous role at EMC (involved in storage) and my current role at VMware focused on network virtualization (which encompasses SDN), I was quite curious. Even so, I’m going to keep an eye on Jeda to see how things progress. Jeda Networks describes themselves as a “software-defined storage networking” company.

I’m a CLI fan, so I like this sort of stuff. I think that’s the point Ivan tried to make as well—it’s the architecture and how OpenFlow is used that makes a difference. (Is If I can ever get my home lab into the right shape, I’m going to do some testing with this. Virtualization.
