"I have worked in environments where reacting was the "normal" way to approach issues and being proactive was just a waste of time... *facepalm* The seemingly simple idea of changing the workplace culture from reactive to proactive was hard to pitch, let alone implement on my own. 18 months ago, I knew there was a better way of doing things and I was determined to find something. I had been watching developers implement Agile Development processes with great envy and I was starting to see concepts that would have great outcomes if adopted in a traditional operations environment. Finally having something tangible to explore I started looking into Agile Operations, which led me DevOps. Lurking in the shadows for a while, I digested as much as I could of the DevOps movement. I thought it was  time to talk to some of the developers and get them on board. 6 months on and here we are... "

Until recently I was not able to clearly articulate what DevOps is. Then one day, when trying to describe what we are building at Nirmata to an investor, I said something to the effect of, "its all about enabling developers to perform operations, using automation". That made sense to them; and, I've since started using the following definition for DevOps: Developers doing Operations using Automation

We have a variety of tutorial videos all related to DevOps. Our goal is to make the lives of SysAdmins everywhere easier by helping them use the tools that developers have been using for a long time, as well as helping developers realize how to solve some of the issues that Operations has traditionally had to deal with. If you have any comments or suggestions, please let us know!

The DevOps team is "a growing group of people practicing a new way of combining development and system administration for more speed, quality, revenues and fun."

DevOps: A culture where people, regardless of title or background, work together to imagine, develop, deploy and operate a system.

As a developer and sometimes system administrator, one of the scariest things I ever encounter is a server that's been running for ages which has seen multiple upgrades of system and application software. Why? Because an old system inevitably grows warts. They start as one-time hacks during outages. A quick edit to a config file saves the day. "We'll put it back into Chef later," we say, as we finally head off to sleep after a marathon fire fighting session.

Vagrant automates creation and provisioning of virtual machines within VirtualBox via the command line, whilst also allowing for easy distribution and reuse across multiple projects. In this article, I'm going to look at how it can make life considerably easier when dealing with development environments.

Although Puppet Enterprise gives you the wonderful tools to automate your Linux administration, you still cannot deploy a server with a single command. With the following script, you can. Why is this so cool? When, for instance, a new Tomcat server is needed, I create a DNS entry for that server and give a single command and get some coffee. Before it has cooled down enough to drink, the developer has his Tomcat-app deployed and the server is operational. (It takes about 8 minutes to get from scratch to a fully operational server.)

DevOps is een reactie op de onderlinge afhankelijkheid van software development (Dev) en operations (Ops). De spreekwoordelijke muurtjes tussen de Dev en Ops afdeling bestaan niet meer binnen DevOps. De implementatie van DevOps resulteert in een versnelling van de ' time to market' en een verhoging van de kwaliteit van delivery. DevOps gaat een stap verder in de richting die met Agile werken al is ingezet. Waar bij Agile werken frequent werkende software met de meeste toegevoegde waarde wordt opgeleverd, gaat DevOps nog een stap verder door de applicatie delivery te versnellen.

The Shutl engineering team has been operating with a DevOps mentality for over two years. We started by rebuilding our infrastructure under Chef and embedding our operations engineers into our agile product development process. We made great progress and saw a big improvement in delivery and quality as all team members were responsible for getting things live and ensuring their long-term maintainability. But… we still had a silo. Only a few of our team were doing the lion's share of the work when it came to maintaining our infrastructure, and on-call duties were shared by just a small number of people. Over the past six months, we've changed that. So, rather than extol the virtues of this approach - there are plenty of articles doing that! - we thought we'd share some of the steps we took to make every engineer a DevOps engineer.

... created a tool which will allows their customer-facing engineers to programmatically deploy infrastructure for new customers and to update the infrastructure of existing customers through a single, defined interface. This tool uses Consul as the foundation for continuous deployment to these environments. Consul's DNS, Key-Value store, and GUI have given DeltaForce a simple mechanism for reliably delivering software.

Bent je nog druk met Agile implementeren? Wees je er dan van bewust dat de volgende vloedgolf aan veranderingen er al weer aan komt. De golf DevOps maakt af wat Agile begonnen is: technologische en procesmatige integratie tussen ontwikkeling en beheer. Waar Agile zich primair focust op klant en it-vernieuwing, wordt met DevOps definitief de laatste muur geslecht: die voor de beheerafdeling. In deze blog licht ik een tipje van de sluier van DevOps op.
