CI – what good looks like…
Changes constantly pushed to version control
Fixing a broken build is always the priority
Nobody goes home on a broken build

Stop the assembly line!
What about tools?
THEY WANTED MORE AGILITY,
SO WE SOLD THEM $2M IN DEVOPS TOOLS
Continuous Delivery Principles
Each check-in is a candidate production release
The same processes and tools in ALL environments
A failure at any stage stops the production line
It’s not about the tools!

I CAN HAZ CONTINUOUS DELIVERY?
Fail-fast
Microservices
Metrics and
Logs
Independently deployable and scalable

Failure is unavoidable. Deal with it.

WORKED FINE IN DEV
OPS PROBLEM NOW
Smooth Collaboration Fully Embedded Infrastructure-as-a-Service
DevOps as a Service Separate DevOps Team
DevOps Culture: Which one is right
for you?

FIRED YOUR EXISTING TEAM AND
REPLACED THEM WITH A DEVOPS TOOL?
THAT MUST BE GOING WELL
Organisation and Culture
Align to business priorities
Quality is everybody’s responsibility
Define your own DevOps Culture
People over processes and tools
