Agenda
• What is Continuous Delivery?
• Why would you want it?
• What do we have to get right?
• Impedance: People
• Impedance: Infrastructure
• Impedance: Software Products
• Impedance: Complexity
@markosrendell 3
What is Continuous Delivery?
An approach to industrialising your delivery
@markosrendell 4
What is Continuous Delivery?
http://markosrendell.wordpress.com
A focus on Flow
@markosrendell 5
Why would you want continuous delivery?
Happiness through a happy organisation

Impedance: People
Ignorance? Ambivalence?
@markosrendell 12
Impedance: People
Obedience? Disobedience?
@markosrendell 13
Impedance: People and Governance
Who “owns” these lovely things?
@markosrendell 14
Dev Ops
UI
agency
Cloud
“Ops”
(possibly
shadow!)
Traditional
operations
“Heritage
System”
owner Mobile
partners
ERP owner CMS
vendor
CRM
owner
SaaS
(possibly
shadow!)
“Operations”
Impedance: People and Organisational Complexity
Get a DevOps team if that helps you
@markosrendell 15
Impedance: Infrastructure
Best infrastructure team quarter ever – no new servers given out?
@markosrendell 16
Impedance: Infrastructure
Demand “public cloud” equivalent levels of capability and service (or use public cloud!)
@markosrendell 17
Impedance: Infrastructure Code quality
Infra-as-code == Infra-is-code {
Give it the Jenkins treatment!
}
e.g. MySQL
Chef cookbook
e.g. RabbitMQ
Bosh release
Treat you Platform as an Application and engineer it accordingly

Impedance: Complexity
Have a strategy for tracking component integration
