• Agile = why we are here tonight!
• DevOps = Development + Operations
– Its not a role or team
– Its about breaking down organizational silos
– Its about an unhindered flow to “live”
– It includes deployment automation and
“infrastructure as code” (e.g. Puppet/Chef)
– It involves massive culture change

Agile DevOps nirvana
• Fully Done Done (i.e. released into prod)
• Short, value adding, iterations into live
• “Potentially releasable software” is a goal
of Scrum but “continuous software
delivery” is the goal of Agile DevOps
• Real user feedback on real applications

• Are you doing true Agile?
• Testing, testing, testing, TDD, testing
• DevOps is not Super-Ops – its not about
the technology or employing “super
admins”
• Understand where you are, map out a
path towards maturity and take one step at
a time

Knowing you are there
• Volume of production releases increasing
• Time taken for feature releases to
production decreasing (“cycle time”)
• Reducing overall M-T-T-R
