Stubborn guys from operations




Thursday 25 March 2010
Typical
                         chain of command




                         http://www.flickr.com/photos/keepwaddling1/3...
Ops and Sysadmins usually get along




                                          http://www.flickr.com/photos/anjibarton/3...
But devs
       and
    sysadmins

         often
        debate
        about

       ‘quality’




                     ...
Devs:“You
       should
     be able to
    make changes
      faster in
    production”


                         http:/...
Sysadmins:
                                         “You should
                                         Test More”




  ...
Usually results in ....




                                             Fight!




                                      ...
Then the managers created silos

But over time
     developers evolved




Thursday 25 March 2010
They looked on the internet




                                             http://www.flickr.com/photos/gigijin/240099929...
Found
                          new ways
                         to automate
                           the tests
       ...
New ways of

Thursday 25 March 2010
Kept operations
              on a leash




                              http://www.flickr.com/photos/squeakywheel/264379...
And what about the sysadmins?




                                   http://www.flickr.com/photos/24443965@N08/2893354732/s...

                                  http://www.flickr.com/photos/31525296@N06/...
They would go off
    and do their manual
          installs




                          http://www.flickr.com/photos/mai...
Even in terrible conditions




                                              http://www.flickr.com/photos/brianatwebbmoto/...
Just like their role models

Then they started
                          to use kickstarts




                         http://www.flickr.com/photos/ala...
Automated
                         it with ‘ugly’ custom scripting




                               http://www.flickr.com...

                                            =
                                     Lcfg, CFEngine
