One of my readers sent me a lengthy email describing his NSX-versus-ACI views. He started with [slightly reworded]:

What I want to do is to create customer templates to speed up deployment of application environments, as it takes too long at the moment to set up a new application environment.

That’s what we all want. How you get there is the interesting part.

Here’s an interesting blog post (particularly as it’s coming from a well-known cloud evangelist): at the infrastructure level stability matters more than agility or speed-of-deployment. Welcome to real world ;)

Remember the All You Need Are Two Switches saga? Several readers told me they’d like to have in text (article) format, so I found a transcription service, and started editing what they produced and publishing it. The first two installments are already online.

On a related topic: we’ll discuss the viability of this approach in April DIGS event in Zurich, Switzerland.

It’s uncommon to find an organization that succeeds in building a private OpenStack-based cloud. It’s extremely rare to find one that documented and published the whole process like Paddy Power Betfair did with their OpenStack Reference Architecture whitepaper.

I was delighted to see they decided to do a lot of things I was preaching for ages in blog posts, webinars, and lately in my Next Generation Data Center online course.

Highlights include:

Does it make sense to run OpenStack on top of VMware infrastructure? How well does NSX work as a Neutron plug-in? Marcos Hernandez answered these questions (and a lot of others) in the Episode 61 of Software Gone Wild (admittedly after a short marketing pitch in the first 10 minutes).

One of my readers sent me this question:

Have you written something about assessment and planning for migration of traditional in-premise data center network to private or public cloud? There would be hundreds of things to check during assessment and then plan accordingly.

Academically, that’s a wrong way of approaching the problem.

Let’s continue our journey toward two-switch data center. What can we do after virtualizing the workload, getting rid of legacy technologies, and reducing the number of server uplinks to two?

How about replacing dedicated storage boxes with distributed file system?

In late September, Howard Marks will talk about software-defined storage in my Building Next Generation Data Center course. The course is sold out, but if you register for the spring 2017 session, you’ll get access to recording of Howard’s talk.

One of my ExpertExpress engagements focused on networking in a future private cloud that might be built using OpenStack. The customer planned to deploy multiple data centers, and I recommended that they do everything they can to make sure they don’t make them a single failure domain.

Next step: translate that requirement into OpenStack terms.

A month ago I published the video where I described the idea that “two switches is all you need in a medium-sized data center”. Now let’s dig into the details: the first step you have to take to optimize your data center infrastructure is to virtualize all servers.

For even more details, watch the Designing Private Cloud Infrastructure webinar, or register for the Building Next-Generation Data Center course.

After I told you that I’m not going to Interop, I got numerous emails along the lines of “but I was really looking forward to attending your workshop” so I started looking for a solution that would combine the best of online and classroom worlds.

Here’s my first attempt: an interactive online course combining topics from two of my Interop workshops. I’m still working on the detailed agenda and plan to have it ready around May 1st. In the meantime, I’d really appreciate your feedback – leave a comment or send me an email.
