This is the story of how one group inside HP built a culture of continuous delivery using GitHub Enterprise, Chef, and ChatOps. We will talk through how we wired up our continuous delivery pipeline, the challenges we faced, and how HP is using the lessons we learned to help our customers with their own transformations. https://youtu.be/Dge_w0bjGew

4. You’re waiting for a train. A train that will take you far
away. You know where you hope this train will take
you, but you don’t know for sure. But it doesn’t matter,
because we’ll be together.
This is the story of our journey to Continuous Delivery

5. HP is huge

6. Let’s zoom in to…

7. Just our lab

8. About 220 engineers
working on about a
dozen projects

9. A year ago

10. What we did about it
GitHub
Enterprise
Continuous
Delivery

11. How We Built It Out

12. Strategy
• Find champions within organization
• Small de-risking experiments
• Roll out change incrementally
• Continually demonstrate value
• Listen to teams
• Pick appropriate battles

13. GitHub Pull
Request Builder
Plug-in
1. Let’s Collaborate!

14. 2. Jenkins: Not just for PRs anymore
Sinatra App
Centralized
logic of what
to call when
we receive an
event
GitHub API

15. 2. Jenkins: Not just for PRs anymore
Chef Server
Sinatra App
Centralized
logic of what
to call when
we receive an
event
GitHub API
System
sudo chef-client

16. 3. Deployments API
Chef Server

17. What’s Awesome: Automation stays out
of developers’ way
Projects can pick-and-choose what to
adopt

18. What a Chef recipe pull request looks like to a
developer

19. What a Deployment looks like to a developer

20. Started with low-risk, low-visibility projects
Demonstrated value:
• Iterate faster with better visibility
• Better team collaboration with less time wasted
• Able to fix problems faster
• Systems and deployments are consistent
Now using these methods to develop HP Support Automation 2.0
– Large, high-visibility project
Pattern used for a bunch of different
projects

21. Add system provisioning to pipeline
Move more teams on board
Improving existing automation
Still more to do internally in my lab

22. Our lab now

23. Exciting times in my lab,
but zooming out…

24. Challenges in the neighborhood:
Isolated GitHub Enterprise instance

25. Exciting times at HP: Continuous Delivery Pilot
New policies emphasize enabling dev teams using whatever delivery
pipeline works for them. Focus on API for shared
reporting/compliance.

26. The situation before my lab’s transformation isn’t atypical of large
customers. A lot of large companies are facing the same need to
migrate to a culture of continuous delivery
New HP Datacenter Infrastructure Automation COE team formed to
help HP Datacenter Care customers through their own Continuous
Delivery journeys
Jared and Andy are just some of the team members “on the ground”
helping HP customers deliver value faster all day, every day.
Exciting time to be an HP customer
