Improving your services, the DevOps way

devops-italiaOn March 10th I was in Bologna for Incontro DevOps Italia 2017, the Italian DevOps meeting organized by the great people at BioDec. The three tracks featured several talks in both Italian and English, and first-class international speakers. And, being a conference in Bologna, it also featured first-class local food that no other conference around the world will ever be able to match.

Report from Config Management Camp 2015

cfgmgmtcamp-logoThe Config Management Camp 2015 is gone leaving its trail of inspiring presentations, interesting discussions, pleasant meetings with great people and, hopefully, satisfaction for how each of us has played his/her part to make this edition a success.

A big thank for the brave people that attended my seminar and to those who asked questions. The questions gave me a couple of ideas to further expand the seminar, and more may come if you’re so kind to let me know your opinion on the talk: what you liked, what you didn’t, what could be improved in both the talk and the speaker’s style. Thanks in advance. As for the code of the tools, I promise to publish it on GitHub as soon as I get “clearance” (this week, possibly!).

For those who weren’t at the seminar, I presented how we evolved our git repository structure to support more than one project, each one with its own needs, but at the same time being able to share the relevant common libraries and tools and to make the deployment of the policies easy, manageable and maintainable, whatever the number of hubs and projects involved. The questions dove nose down to how we manage access to the hubs so that a person working on project A can’t accidentally deploy his policies on the hubs supporting project B, how we manage access rights to files in separate projects and to branches, and how easy or hard is to extend the deployment tool with new functionality.

The slides of the presentation are on SpeakerDeck (or further down the post if you don’t bother go to SpeakerDeck 😉 The good guys at Normation also filmed the seminar, so it’s just a matter of time that a video of the seminar will be available. Then you’ll also be able to hear my appeal to support cancer research, talking of which you can check another blog post of mine.

Regarding the talks I attended and the “hallway track”, Jez Humble’s keynote was definitely a mind blowing experience. Leaving aside the things that I am doing wrong, that we are doing wrong in my work environment, and that a broad set of people in our profession is f***ing up completely, I understood that there is a category that definitely needs to be more present at events like this: bosses. Because we can do a good job as professionals, follow the best practices, use the brightest and shiniest tools of today and some of the tools of tomorrow, but that’s definitely not enough to establish a culture of cross-area collaboration. That’s not going to happen without the direct involvement of the bosses and their mandate.

My round of conferences in February

cfgmgmtcamp-logoThe first half of February is going to be quite busy to me with two conferences just a few weeks away now.

On February 2nd and 3rd I’ll be at the Configuration Management Camp in Ghent, Belgium, where I’ll hold the seminar “Many projects, one code” on the 3rd. A little more than a week later, the 12th of February, I’ll then be at Software 2015 in Oslo, where I’ll hold the seminar “The classification problem: challenges and solutions” in the Continuous delivery and DevOps track. And yes, the slides will be available on my SpeakerDeck account as soon as a seminar is done.

The classification problem: challenges and solutions

Update March 1st, 2015: the latest version of the code for hENC is now on github

It’s been about a month since I came back from FOSDEM and cfgmgmtcamp, a month where I gradually recovered from the the backlog both in the office and at home. It’s been a wonderful experience, especially at cfgmgmtcamp, and I really want to thank all those that helped make it special — more details at the end of this article.

But promise is debt (no pun intended with promise theory here), and I promised to write a long blog post with some (or all) the details from my talks. It’s time to keep that promise. So, without any further ado…

My talks at FOSDEM and cfgmgmtcamp

FOSDEM'14 logoThanks to all those who attended my talks at FOSDEM and cfgmgmtcamp, and double thanks to all those who also showed their appreciation: you made that experience a memorable one!!!

I have uploaded my slides on SpeakerDeck soon after my talks were over. Here you are the FOSDEM deck:

A video of the talk has also been released, but it’s unfortunately mute 😦 I hope that it will be fixed soon.

cfgmanagementcampAt FOSDEM I had only 20 minutes (that is: 20 plus questions, up to 25). However, the subject deserved to be dealt with with more attention. At cfgmgmtcamp I had 40 minutes — well, in the end they were only 35, but that’s Jonathan Clark’s fault ;-) so both the talk and the slide deck were more detailed than the ones from FOSDEM:

The plan is now to “unroll” the cfgmgmtcamp’s talk, and write an article from the transcript of the talk. It will take some more days however, but it will definitely come. Stay tuned!

I’ll be presenting at FOSDEM and cfgmgmtcamp

I’ll be presenting at two conferences in two weeks.

fosdem-logoOn February 1st and 2nd I’ll be at FOSDEM in Brussels, where I’ll present the seminar “The classification problem: challenges and solutions“. In 20 minutes I’ll try to give you an idea of why classification in configuration management is critical, why it is difficult, and how you can make it sane.

cfgmanagementcampSince 20 minutes may not be enough to treat the subject in detail, I got the opportunity to explain things in full at the Configuration management camp in Gent/Ghent/Gand, that will take place on February 3rd and 4th. I’ll be in the CFEngine / Rudder Community Room and will have 40 minutes to present “External node classification, the CFEngine way”. It’s the same seminar as FOSDEM; however, I’ll be able to show some examples of what makes classification difficult when you try to do it only “internally” with your CM tool of choice, and I’ll be able to show analogies and differences between Puppet and CFEngine when it comes to external node classification.

I hope to see some friends from the community there. If you’re going to any of these conference and want to say hello, just reach out 😉
