Late last week, Cyrus Durgin from Luminus Networks published an article on SDx Central titled “The (R)evolution of Network Operations.” You may notice that my name is mentioned at the bottom of the article as someone who provided feedback. In this post, I’d like to share some thoughts—high-level and conceptual in nature—on network operations and Luminus Networks.

In this post I’ll build on my earlier introduction to Terraform to show a practical example of using Terraform to build a CoreOS-based etcd2 cluster on OpenStack. This information is based upon a demo that I created for a session at the Austin OpenStack Summit in late April, so all the files I reference in this post are available in the GitHub repo for that session.

In this post, I’m going to walk you through the process I used to build a Vagrant box for Cumulus VX that will work with VMware desktop hypervisors (like VMware Fusion or VMware Workstation). Although Cumulus Networks offers several different versions of Cumulus VX to download, they do not (strangely enough) offer a Vagrant box that will work with VMware’s desktop hypervisors.

In this post, I’m going to walk you through the steps to install Ansible 2.x into a Python virtual environment (virtualenv) on OS X. There’s nothing terribly hard or unusual about this process, but I wanted to document it here for folks who might be new to the process (or who might be interested in why using this approach could be beneficial).

A large portion of the OpenStack community is gathered in Austin this week for the Spring 2016 OpenStack Summit. As I’ve done at previous Summits (and other events), I’m offering to gather with other Christian believers for a brief time of prayer in the mornings before the sessions kick off each day.

Welcome to Technology Short Take #65! As usual, I gathered an odd collection of links and articles from around the web on key data center technologies and trends. I hope you find something useful!

Welcome to Technology Short Take #64. Normally, I try to publish Short Takes on Friday, but this past Friday was April Fools’ Day. Given the propensity for “real” information to get lost among all the pranks, I decided to push this article back to today. Unlike most of what is published around April Fools’ Day, hopefully everything here is helpful, informative, and useful!

I wanted to provide readers a quick “heads up” about some unexpected behavior regarding Docker Machine and OpenStack. It’s not a huge deal, but it could catch someone off-guard if they aren’t aware of what’s happening.

Long-time readers know that my wife, Crystal, has been running this thing called Spousetivities for a few (OK, eight) years now. While Spousetivities originally started out as a VMworld thing, it rapidly expanded, and this year Spousetivities will be at a number of events. That includes the spring OpenStack Summit in Austin, TX!
