A little bit of history…

How did DevOps get its’ name?

Agile Systems Administration Group

#DevOps

What’s in a name?

DevOps

devops

Devops

“I picked ‘DevOpsDays’ as Dev and Ops working together because ‘Agile System

Administration’ was too long,” Patrick Debois

Why Development and Operations?

Value stream

Requirements are defined Value is delivered

What else has led to DevOps?

The Lean Movement •  Started in the early 1980’s as an attempt to codify the

Toyota Production System •  Focusses on how to create value for the customer •  Thinking systemically •  Creating constancy of purpose •  Creating flow and pull (versus push) •  Embracing scientific thinking •  Assuring quality at the source •  Leading with humility and respecting every individual

The Agile Movement •  Started in 2001 by 11 of the leading thinkers in software

development •  Some of the key principles are -

•  develop working software frequently, from a couple of weeks to a couple of months, with a preference to the shorter timescale

•  business people and developers must work together daily throughout the project

•  build projects around motivated individuals. Give them the environment and support they need, and trust them to get the job done

The Continuous Delivery Movement

•  Started by Jez Humble •  Defined a deployment pipeline that ensures code and

infrastructure are always in a deployable state •  That all code checked into trunk is deployed into production

The Lean Startup Movement

•  Started by Eric Ries •  Codified the practices and terms such as

•  Minimal Viable Product (MVP) •  Build / Measure / Learn cycle

•  Technical patterns around Continuous Deployment

Cloud and Platform as a Service (PaaS)

•  Amazon Web Services (AWS) •  Microsoft Azure •  IBM SmartCloud •  Red Hat OpenShift •  VmWare Cloud Foundry

“But what is DevOps, you ask?”

“What is not DevOps?”

DevOps is not Dev doing Ops

DevOps is not Ops doing Dev

DevOps is not NoOps

DevOps is not one person doing everything

DevOps is not a process

DevOps is not a policy

DevOps is not a procedure

DevOps is… …not really anything new

However, it may be a new way of working

DevOps is a cultural change

DevOps is automation

DevOps is Lean

DevOps is measurement

DevOps is sharing

You are either building a learning organisation…

…is still a bad process

Is not just about the tools
