Continuous Integration for the World

In 2008 at Agile Toronto, I did a session on Agile Infrastructure. This is where I met Andrew Shafer (working at Reductive Labs). There wasn't that much attention for it back then, we were still figuring out the impact and ideas. Now 3 years later, I was keen on doing a follow-up at the big Agile2011 conference in Utah.

I had the pleasure to co-present with the illustrious Julian Simpson (aka Build Doctor).

The talk was based on showing off a few of the tools that are currently used in the devops space and pointing out the similarities between the release process of code and the release process of servers:

Thanks to the concept of infrastructure as code and virtualization, we can define and build our infrastructure based on textfiles. Those files can be version-controlled and tested like regular code. The artefact (ami, image), can then be deployed on an infrastructure. The following image gives you an overview on the similarities.

Some people have asked for an overview on how all these tools relate to each-other. Therefore I started with the following overview to make understandable. I'd love to hear your comments on it.

I love the diagrams. They do a good job showing how "infrastructure as code" is very analogous to "code as code". It's been an eye opener coming from Ops to see how much of a software developer an Ops person needs to become to be successful with "infrastructure as code". As I was processing your code diagram I made column headers (source, compile, package, integration, deploy) and found for the integration header you could put "runlist" as the analogy for Chef as it is a grouping of recipes (and more) for a larger purpose (an integration). I think a role would be a package, because in itself it is not a complete thing, but it is a grouping of other things.
