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

What about tools?

THEY WANTED MORE AGILITY,SO WE SOLD THEM $2M IN DEVOPS TOOLS

Continuous Delivery PrinciplesEach 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 components

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 ANDREPLACED THEM WITH A DEVOPS

TOOL?

THAT MUST BE GOING WELL

Organisation and Culture

Align to business priorities

Quality is everybody’s responsibilityDefine your own DevOps Culture

People over processes and tools
