Technology Short Take #63

Welcome to Technology Short Take #63. I’ve managed to (mostly) get back to my Friday publishing schedule, though I’m running much later in the day this time around than usual. I’ll try to correct that for the next one. In any case, here’s another collection of links and articles from around the Net on the major data center technology areas. Have fun reading!

On the Topic of Lock-In

While talking with customers over the past couple of weeks during a multi-country/multi-continent trip, one phrase that kept coming up is “lock-in”, as in “we’re trying to avoid lock-in” or “this approach doesn’t have any lock-in”. While I’m not a huge fan of memes, this phrase always brings to mind The Princess Bride, Vizzini’s use of the word “inconceivable,” and Inigo Montoya’s famous response. C’mon, you know you want to say it: “You keep using that word. I do not think it means what you think it means.” I feel the same way about lock-in, and here’s why.

Technology Short Take #62

Welcome to Technology Short Take #62. Sorry for the long delay since the last TST; some global travel has really thrown my schedule off. In any case, I didn’t want to wait until Friday (the day I normally publish these) so I’m putting this out there sooner. Enjoy!

Full Stack Journey Episode #3: Jonathan Frappier

In Episode #3 of the Full Stack Journey podcast, I have the pleasure of speaking with none other than Jonathan Frappier. Jonathan blogs at VirtXpert, and is probably quite well-known for his role in wrangling speakers for the vBrownBag podcasts. Jonathan is @jfrappier on Twitter, and uses the same username on GitHub as well. Jonathan’s been in the IT industry for, as he puts it, “somewhere between 16 and 20 years.” Today, Jonathan and I talk about PowerCLI and leveraging the rest of your team at work to help with your success in making the journey to being a full-stack engineer.

Talking Containers, Virtualization, and Interop

Last year, I had the pleasure of attending and speaking at Interop for the very first time. (I did some liveblogging while I was there; here’s a list of the liveblogs published from last year’s Interop.) Fortunately, I was invited back again this year (very excited about that!), and as a returning speaker I recently had the opportunity to do a podcast with Technology Advice about SDN, virtualization, containers, and Interop.

Using KVM with Libvirt and macvtap Interfaces

In this post, I’m going to show you how to use KVM with Libvirt and macvtap interfaces for networking (as opposed to a Linux bridge or Open vSwitch). Along the way, I’ll provide some context around why this sort of approach might be interesting/useful to you.

Brief Site Update

As many of you may already know, GitHub recently upgraded GitHub Pages to use Jekyll 3.0, and along with that upgrade comes a few (relatively) minor changes to the site as a result. Here are the details of what’s changed here.

Full Stack Journey Episode #2: Matt Oswalt

In Episode #2 of the Full Stack Journey podcast, my guest is none other than Matt Oswalt. You may know Matt as the primary author at Keeping It Classless, or as @mierdin on Twitter or GitHub (he also has a YouTube channel and a podcast of his own). Matt is primarily focused on network infrastructure, but is really interested in the intersection of network infrastructure and software development. Matt, along with Jason Edelman and yours truly, is one of the co-authors of a new book on network automation and programmability, and as such is a perfect guest for the Full Stack Journey.
