Background

•  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

Problem


Project Services


Agile North East

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

How

Develop Unit Test Integra>on Test

Acceptance Test

Performance Test

Automated Automated Automated Automated Manual Should Be Automated

Deploy to Live

•  Automate everything


Project Services


Agile North East

How

•  Automate everything •  Version everything •  Automate provisioning (of infrastructure)

and deployment (of software) •  Implement a visible deployment “pipeline”

with regular feedback loops

The pipeline

Version Control System

App + Infrastructure code

Scrum Delivery Team

Con>nuous Delivery

Build + Deploy Tests

Quality Gates

e.g. CAB

Other tests func>onal, performance, pen, etc.

Automate Approval Processes

Move from explicit to implicit approval

Con>nuous Live

Deployment

Live deployment, environment refresh

Impact on Scrum

•  Product Owner understands operations •  Backlog includes ops-related stories •  Ops are represented in “the team” •  Definition of done includes getting into

prod •  Ceremonies includes ops people •  Scrum used to fix production defects


Project Services


Agile North East

Changes needed

•  Ops writing code (“full stack developer”) •  Developers deploying to prod •  Ops + Dev on the same Agile team •  Ops moving into the Agile world •  Versioning of infrastructure (as code) •  NFR’s in story acceptance criteria

Moving forward

•  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


Project Services


Agile North East

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

•  You’ve annihilated the CAB!
