OpenStack Architecture and Design Book Sprint

In just a few weeks, I’ll be participating in a book sprint to create a book that provides architecture and design guidance for building OpenStack-based clouds. For those of you who aren’t familiar with the idea of a book sprint, it’s been described to me like this:

Docker Making Its Move

Today marked the start of Dockercon, and Docker, Inc., the commercial entity behind the incredibly popular open source Docker project, is taking this opportunity to make its move. Already the focus of quite a bit of attention (some might say a disproportionate amount of attention), Docker is making several announcements today that indicate an intent to broaden its reach:

Thinking Out Loud: Handling Career Evolution

As IT pros at the “cutting edge” of technology and industry change, I think sometimes we forget that not everyone has the same mindset toward learning, growth, and career evolution. That’s especially true, I think, for those of us who are bloggers, because it’s our passion for the technology that not only drives us to write about it but also drives us to constantly explore new trends, new areas, and new concepts. It is that passion that drives us to seek out new ways the technology could be applied to our jobs. That passion sustained us over the years, as we progressed from Windows admins to VMware admins and now to virtualization and cloud architects. That passion led us to “bring our work home” and build home labs. We’ve had years of actively seeking out new layers of knowledge to build on top of what we already knew.

Some Useful Markdown Tools for OS X

I don’t think that it is any secret that I’ve become a big fan of Markdown (MultiMarkdown to be precise; more on that in a moment) over the last couple of years. Likewise, it’s not really a secret that I’m an OS X user, although my “fanboi” status for OS X has waned a bit since the introduction of Lion and Mountain Lion (neither of which are as good, in my opinion, as Snow Leopard, but that’s an entirely different discussion—the jury is still out on Mavericks). In this post, I want to share with you a few Markdown tools for OS X that I’ve been using and that (hopefully) you’ll find helpful as well.

Another Look at an OpenStack Heat Template

In an earlier post, I provided an introduction to OpenStack Heat, and provided an example Heat template that launched two instances with a logical network and a logical router. Here I am going to provide another view of a Heat template that does the same thing, but uses YAML and the HOT format instead of JSON and the CFN format.

An Introduction to OpenStack Heat

In this post, I’m going to provide a quick introduction to OpenStack Heat, the orchestration service that allows you to spin up multiple instances, logical networks, and other cloud services in an automated fashion. Note that this is only an introductory post—I’m not an expert on Heat, but I did want to share at least some basic information to help others get started as well.

vSphere Network Health Check and Cisco UCS

Reader Brian Markussen—with whom I had the pleasure to speak at the Danish VMUG in Copenhagen earlier this month—brought to my attention an issue between VMware vSphere’s health check feature and Cisco UCS when using Cisco’s VIC cards. His findings, confirmed by VMware support and documented in this KB article, show that the health check feature doesn’t work properly with Cisco UCS and the VIC cards.

Learning NSX, Part 13: Revisiting Logical Networking

Welcome to part 13 of the Learning NSX blog series, in which I revisit the idea of logical networking with VMware NSX. This is a topic I first discussed in part 5 of this series, but I want to go back and look at it again, this time from a more practical perspective of what it looks like to use VMware NSX for logical networking in an OpenStack environment.
