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
The CAMS Model
The CALMS Model

Fail fast, fail forward

You are either building a learning organisation…
C A L M S
…or you will be losing to some who is
The learning organisation
C A L M S
is one that has the capacity to integrate people and structures in order to move toward
continuous learning and change
Continuous learning
C A L M S
represents an organisation’s effort to create learning opportunities for ALL of its members
Shift from a technology obsession…
C A L M S
…to a customer obsession.
Delight your customers

Shift from organisational silos…
C A L M S
…to a more collaborative model
Shared Objectives

Speed can be dangerous
C A L M S
Don’t automate what you don’t understand
C A L M S
A bad process automated…
C A L M S
…is still a bad process
Is not just about the tools
C A L M S
Don’t automate what you cannot validate…
C A L M S
…automatically
