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 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. MySQLChef cookbook

e.g. RabbitMQBosh release

Treat you Platform as an Application and engineer it accordingly

@markosrendell 18

Impedance: Software Products

Tame the COTS products – it IS possible!

Build Static Code Analysis

Deploy Code

Load Test Data

Run Test Harness

SCM Repo

Impedance: Complexity

What versions were

tested together?

What should

we release?

How do we control flow?

Have a strategy for tracking component integration

@markosrendell 22

Integrated Pipelines

CI pipelines

Integrated pipelines work really well
