my immutable infrastructure ignite – the references
DevOpsDays Tel-Aviv happened a couple of weeks ago. This was my first ever attempt at doing an ignite talk. Preparing and delivering it was both challenging and a lot of fun. The subject of the talk was Immutable Infrastructure and while there’s no point in posting the slides on their own (the main point in ignite is saying things and not showing slides) – there are a few links that I used when preparing for this talk and would now like to share with you. This is also important as there was no time for the references slide at the talk itself – so here are the references: Chad Fowler of course: http://chadfowler.com/blog/2013/06/23/immutable-deployments/ Florian Motlik of Codeship: https://blog.codeship.com/immutable-infrastructure/ Boxfuse blog: https://boxfuse.com/blog/no-ssh.html This O’reilly article by Josh Stella: http://radar.oreilly.com/2015/06/an-introduction-to-immutable-infrastructure.html And this interview with 6 experts from HighOps: https://highops.com/insights/immutable-infrastructure-6-questions-6-experts/
DevOps Days TLV
I’m excited to be giving an ignite talk at DevOps Days Tel-Aviv 2015. The talk will be my observations regarding pros and cons of immutable infrastructure – here’s the description: http://www.devopsdays.org/events/2015-telaviv/program/ignite_anton_weiss.html If you haven’t heard about the ignite format – here’s a short description: “These are 5 minute talks with 20 slides which auto-advance. If you aren’t familiar with the format, good examples can be found at http://igniteshow.com/” It’s one agile presentation 🙂 Hope to see you there!
The First Date with Silicon Valley.
I’m writing this on the plane on my way to San Francisco. Am I excited? Sure I am – this is my first visit to the US! It may seem pretty strange – I’ve been working in software for the last 15 years – most of the time on projects involving the American market. And still I never traveled for work. I even had a planned trip once, got a visa issued, but the project then fell through… On the other hand – this makes enough sense as I’ve spent most of my career working on infrastructure. And in this field (as in many others) there’s increasingly less need to be in a specifi place to do your work. As an example – I just spent 4 very productive hours in Frankfurt airport – sending mails, fixing bugs, talking to a customer and preparing a talk proposal for the upcoming…
On change and jellyfish.
I’m on vacation with my family at the Curonian Spit in Lithuania. This is a breathtakingly beautiful place – a thin stripe of sand dunes and pine woods washed by the Baltic Sea on one side and the Curonian Bay on the other. There are bike routes running through the whole length of the spit, an endless sandy beach, and plenty of wild birds and animals. The food is cheap and the Lihuanians are friendly. We all had a lot of fun biking, walking and bathing in the cold waters of the Baltic. For me this is also a nostalgic experience – I’ve spent most of my childhood summers on the Baltic Sea. But it’s been more than 20 years since I last tasted its lightly-salted waters (compared to the intense saltiness of the Mediterranean). So the first plunge really brought back memories.The taste didn’t change. But other things did.…
How I get inspired by my kid.
My kids are my source of inspiration. Children in general are bursting fountains of innovative ideas. Some of them make us laugh, yet others annoy the heck out of us, but most of them are exciting. Especially when it’s your own kid who comes up with an idea 🙂 But this time it wasn’t an innovative idea that got me inspired. It was the entrepreneurial spirit and execution of my elder son, Eran. The kid is hooked on a computer game. Which in itself is nothing special. Though the game is quite interesting. He and his friends play Minecraft. Now, I’m always very curious about what excites my children. And I’m the ops guy at home, helping everyone with their tech needs. So I started looking at the game, helping Eran with installing game mods and reading up on the game history and ecosystem. I loved the whole story of the game starting…
How To Hire for DevOps
About the image – I originally thought naming this post “How to Hire Ninjas” but then realised I don’t honestly like the analogy. DevOps people are not ninjas – they don’t work in disguise and aren’t trained from the very childhood. Moreover – this heroical ninja image is actually harmful. It only contributes to the DevOps identity crisis as outlined by Baron Schwartz and lies at the very heart of the problem that I’m trying to suggest a solution for here. It’s no secret that the tech workforce market is starving for DevOps. (I know, I know – DevOps is not a job title, it’s a mindset.) The cloud, BigData and modern software delivery standards all produce the need for professionals who know how to get those complicated systems built, deployed and running. The demand keeps growing and the supply just doesn’t seem to catch up. More and more organisations…
Learning Ansible by Packt Publishing: the review
I got the offer to review this book on Ansible user group in LinkedIn. My previous experience with Ansible dated back about 1.5 years ago and the documentation on Ansible site was quite sufficient to get me up and running. So I was curious to see if the book would offer any substantial added value. I feel like the book’s title is misleading. If you’re looking just to learn Ansible – you’ll probably be better off using the official Ansible docs and walk-throughs. But – this book covers much, much more – e.g: using ServerSpec to test your configuration, building Docker containers, monitoring playbook execution with Nagios, etc. Thus – it provides you with a much bigger picture regarding where Ansible fits into your DevOps ecosystem. And – it can be a reference for all kind of things you might want to do with Ansible in the future – after…
It’s all about trust: from Continuous Integration to Continuous Integrity.
The introduction of Continuous Delivery systems and processes (when implemented correctly) brings four basic values to software development lifecycle: Structure Transparency Efficiency Quality While all of those are very important, today I’d like to put some more focus on just one of them which is sometimes overlooked or not understood correctly – that is Transparency . In fact there’s another ‘T’ word which results from transparency –Trust, and I tend to think it’s the most important quality of a CD process. Automated software delivery systems come to replace and improve the execution of multiple manual tasks involved in releasing quality software to end users. The benefits of automation are clear: create a repeatable process, eliminate human errors, replace expensive human time with cheaper machine time, streamline the tasks and there’s more… But what we must never forget is that there are some perils too. Perils related to putting all the processes under the hood of…
