Dev to DevOps

Law of the Instrument

"If all you have is a hammer, everything looks like a nail."

Abraham Kaplan, 1918-1993 in 1964

Nails are ok.

I can deal with this...

Guitars are awesome!

I like this problem.

How about now?

Now?

More than one tool...

A tool for a big job...

A tool for a complicated job...

A tool to make our job cool and fun...

#devops

No such thing as a DevOps team

Jez Humble, Co-author of Continuous Delivery

[...] the Devops movement addresses the dysfunction that results from organizations composed of functional silos.
Thus, creating another functional silo that sits between dev and ops is clearly a poor (and ironic) way to try and solve these problems.

So what, exactly...

... is the problem??

Danger Zone!

"You need a culture that keeps pushing into the danger zone, and has the habits that enable you to survive in the danger zone."

What does this look like?

Fail.

Puppet Manifest

            
              def github(name, version, options = nil)
                options ||= {}
                options[:repo] ||= "boxen/puppet-#{name}"
                mod name, version, :github_tarball => options[:repo]
              end

              github "gcc",        "1.0.0"
              github "git",        "1.2.2"
              github "homebrew",   "1.1.2"
              github "nginx",      "1.4.0"
              github "nodejs",     "2.2.0"
              github "ruby",       "4.1.0"
              github "stdlib",     "4.0.2", :repo => "puppetlabs/puppetlabs-stdlib"
              github "sudo",       "1.0.0"

Complete fail.

Boxen Project Manifest

            
              class projects::trollin {
                include icu4c
                include phantomjs

                boxen::project { 'trollin':
